In 2007 I graduated from Central Methodist University with my B.S. in Business and Accounting. After my first year as an accountant at Williams Keepers, LLC I knew I couldn’t sit at a desk for the rest of my life. Taking a leap of faith, I decided to follow my passion and became a personal trainer in 2008. 

I grew from working at a corporate gym, to being contracted at a private studio and finally opened up a studio with my wife. 

The industry continues to change; continuing education has been a main objective of mine. I see a lot of individuals pushing themselves to extremes in order to get the results “no matter” the cost. These results are short lived and usually end with an individual being overtrained and finally injured. 

My approach is different and is based in science. I believe in building a program that will get my clients functioning in a pain-free environment. I do this by taking my clients through a comprehensive movement screening that allows me to assess which muscles need to be strengthened and which need to be lengthened. People either become tight through repetitive moment or through staying in an unnatural posture (such as sitting at a computer) for long periods of time. 

Through a corrective exercise program, I get my clients moving and feeling better while they gain experience with resistance training. I progress them through their program as their goals change and their bodies adapt. By periodizing a client’s program, we prevent injury and avoid plateaus and boredom. 

I am also a firm believer in you are what you eat. No matter what your goal is, without proper nutrition it will not be reached.

What would YOU attempt to do, if you knew you could not fail? If you just want to know what I can do for you, skip ahead to the about you section!


I graduated from Lindenwood University with my B.S. in Developmental Psychology. My Personal Training career began in 2005 at 24 Hour Fitness. I earned a plethora of nationally recognized certifications (NASM CPT, ACE CPT, AFAA CPT, NASM CES, NASM PES), acquired the highest rank of Master Trainer and eventually worked not only as a full time Personal Trainer but also as an Assistant Fitness Manager. I spent time coordinating special incentive weight loss challenges, educating other trainers within our district about how to properly assess movement and offer corrective exercise strategies.

By August of 2010, I began working as an independent contractor within an elite private training studio. During this time, I continued to specialize in weight loss and corrective exercise but also began to grow my natural bodybuilding clientele exponentially by offering full service competition prep services: nutrition, weight training, cardio, sleep, hydration, supplementation, peak week, posing suit selection, comparison posing, individual posing routine and in person coaching on the day of show. 93% of my first time competitors have placed top 5 in pro-qualifying events and I was the first and only person in the midwest to offer a free posing clinic weekly for 3 years in a row. Besides coaching individual presentation walks, I’ve also choreographed elaborate posing routines for physique and bodybuilding competitors. Ive also had the pleasure of becoming an NANBF Judge and sitting on the judging panel.

I personally competed from 2005-2013, almost always placing top 3 in my categories. I never quite had what it took to earn my Professional Figure competition credentials though I’ve trained beginner competitors through the novice rankings to the professional circuit. In 2013 I competed for the (tentatively) last time, hanging up my competitor heels for business ownership as my husband and I opened Dudas Fitness. Since opening, I’ve continued to pursue my education so that I can continue to offer the BEST services to my clients. I’ve since earned my Precision Nutrition L1, NASM Golf Specialist and 500 Hour Yoga Teacher credentials.


I specialize in corrective exercise (assessing movement and posture and developing exercise routines to avoid potential injuries or to correct alignment and posture to work around existing ones) and physique changes (weight loss and muscle gaining through nutrition and exercise). This is still a primary service I offer through Personal Training, but I am projected to complete my Professional Yoga Therapist training in 2019 and will begin to offer Yoga Therapy as a service.

After many years of training, I have found that individuals with special considerations always find their way to my door through referrals. I have experience working with and supporting clients who have had joint replacements, back “problems” (herniations, bulges), cancer, auto-immune diseases (such as arthritis, Type-1 diabetes, Hashimoto’s, celiac, ulcerative colitis), neurological disorders/diseases (such as Parkinsons, ALS, Guillain-Barré Syndrome), digestive diseases (Crohn’s, Irritable Bowel Disorder) and much more. My job as their personal trainer has been to customize fitness routines and lifestyle changes to make them as strong and healthy as possible. As a yoga therapist, my scope broadens beyond what i’m capable of addressing as a personal trainer. It is not within my scope of practice to diagnose or treat but rather my role is to assess the whole individual (body, mind, spirit) and offer support through yoga movement (asana), stretches, strengthening exercises, breathing (pranayama), meditation, and a disciplined lifestyle (nutrition, social support, work life, sleep, etc). The role of a Yoga Therapist is to assess the whole individual and to work alongside the specialized care of a medical professional. While I still specialize in corrective exercise and physique changes such as weight loss and muscle gain, I have ultimately found that most people are searching for wellness and optimal living and through Yoga Therapy I am better suited to address those with special medical considerations.


I have learned that people have gotten accustomed to feeling bad. They forget the healing power of functional breathing, optimal mobility and stability, nutrition appropriate to their unique makeup, adequate sleep, working with the natural rhythms of the body and healthy body composition. Instead of merely treating the symptoms of poor health management, begin to thrive and live life more fully.

Success lies in you. My clients are known to lose more weight than they originally thought they were capable of, accomplish physical feats they thought were reserved for those with “youth” on their side, and feel the best they have in their entire lives. While my personal experience and extensive education means that you and your goals are in good hands, it is my positive attitude, encouragement, and patience that will lead you to success… beyond!

I have always had a passion for fitness and for helping others, and a career in personal training is the perfect way for me to blend those two passions. From a young age, I knew I wanted to help people to learn how to be healthy so I decided to obtain my bachelor’s degree in Exercise Science from the University of South Florida. 

In 2006, while still in my undergraduate program, I began my personal training career at a small fitness studio in Florida where I also worked as a physical therapy technician. This helped me to gain invaluable knowledge and experience on how the body recovers after an injury and proper body mechanics. After completing my undergraduate degree, I returned home to St. Louis and began training at a large gym. After a few years of training, I decided to take my career to the next level and began teaching people to become personal trainers at a local college. During this time, I also obtained my master’s degree in Fitness Management from Missouri Baptist University. As much as I love teaching, I missed training and working with my clients, which is what brought me to start Fit Rx LLC inside of Dudas Fitness. 

I believe fitness should be fun and an enjoyable experience. I have worked with a wide variety of clients, including athletes, seniors, clients wishing to gain muscle, clients wishing to lose fat, and everything in between. Whatever your goal may be, I look forward to helping you achieve it!”

In 2006 I became a personal trainer, and I have never had a bad day at work since. Having the trust of someone who wants to make healthy changes in their life is a great honor. And, it is never lost on me! My approach to wellness is holistic. For exercise, I love functional bodyweight movement (yoga, crawling); Circular strength training (kettlebells, macebells); and martial arts (boxing, kickboxing). For nutrition, I feel that when you make nutrient dense whole foods a priority, everything else will fall in line. For mindset, I turn to my skill set as a certified hypnotherapist, certified NLP Practitioner, and Certified Life & Success coach to rid you of your limiting beliefs and build your self confidence! Believe in yourself!

My Passion…

I stumbled into the fitness industry at a young age and consider it a blessing to have found my passion so early. My passion is to love and encourage others by helping them achieve their full potential physically, mentally, and spiritually. Never settle for a life that is less than the one you are capable of living.

My Certifications and Training… 

I’m a NASM Certified Personal Trainer with specialty certifications in Corrective Exercise, Titleist Performance Institute Level 1, Prenatal/Postnatal Fitness, Group Exercise, Precision Nutrition and Thai Bodywork. I have been teaching different classes for over a decade and have taught everything from Bootcamp, Circuit Training, Zumba, Yoga/Pilates, Aqua Aerobics, Buti Yoga and many more.

My Path…

I earned my Bachelor’s degree at Missouri State in Recreation with an emphasis in Health and Wellness, graduating in 2008. While earning my degree, I worked at Curves Fitness as a Weight Loss Specialist and Nutrition Coach. After college, I moved to Groton, CT to work at the Naval Submarine Base for MWR as a Fitness Instructor. There I spent three years organizing, leading, and training individual and large groups of active military commands, dependents, and civilian workers. In 2011, I moved to Kittery, ME following my husband’s military career and worked at Coastal Fitness and the YMCA as a Group Instructor  and as a Personal Trainer for a private studio, Fitness Together. Moving back to Missouri in 2012, I started at Club Fitness and quickly advanced to an Elite Trainer. It was about two years later when I started competing in Bikini Bodybuilding and met the Dudas Family. I joined the Dudas Team in 2013 which led to #CKeevilFit. Since joining the team, I have found a love for Thai Bodywork and am excited to see what the future brings with working with an amazing group of professionals.

In My Senior year of High school it was very clear I had taken an interest in Anatomy and Physiology and the systems of the body. Immediately after High School graduation I enrolled in the Massage Therapy Program at Missouri College in St. Louis, Missouri, Oct 2003. In May of 2004 I graduated with Top Honors in my class and later went on to work as a Massage Therapist. After trying out a couple different job settings etc, I found myself in a gym setting and really enjoyed it. The clients were very health conscious and it was great for regular business for me. In 2008 I furthered my LMT education receiving a rare certification in Ashiatsu (Foot Pressure) Bar Therapy and in 2009 received another rare certification in Thai Massage (Advanced Stretch technique). I am also trained in Deep Tissue and Pre-Natal massage as well. 

After 3 years of working in a Personal Training Studio I decided to take my training to the next level by training for a Figure Competition. I bought my 1st gym membership in 2003 and worked out routinely for 5 years but was never very serious about it. Throughout those years I had always been told I had great structure, size and symmetry for those competitions and that I would do well. In 2010 won the Figure Overalls at my 1st 2 shows, then went on to compete Nationally, becoming a consistent Top 5 placer for 2 yrs. In November 2012 I received the highly sought after IFBB Professional status in Figure. 2013 has been my 1st year on the IFBB Pro stage, and I finished 7th back in March at my Pro Debut, the IFBB St. Louis Pro. This year I have also gotten into the judging side of things during my off season. August of this year I graduated as an NPC Official judge and I look forward to judging in 2014 for the NPC Organization!

While working in the private Personal Training studio for 4 years and competitively competing in NPC Figure, I was inspired to study and receive my CPT Certification through ACSM. This Certification was one of the Gold standards in Fitness and I wanted one of the best recognized. I have been doing both Personal Training and Massage Therapy for the last 2 years and it has made me very versatile in my work environment. As a LMT, ACSM CPT, IFBB Pro, I look forward to bringing alot to the table in serveral aspects of Fitness, personal or professional with Dudas Fitness!

It is my passion and duty to inspire those to be the best version of themselves possible for quality of life and well being!

Casey believes the therapeutic value of exercise is priceless, yet the most underutilized anti-depressant.  Lacking physical activity and poor nutrition will not achieve an optimal quality of life.  Most people exercise to look good and Casey believes exercising to feel great should be a priority.  As the years go by, people need to become increasingly aware of exercise to maintain good physical and mental health. 

Casey started personal training as a part time job while making a living as a meat cutter.  However he needed a change. A love for the lifestyle and having family involved with training opened the door.  In a very short period of time, it became clear to Casey he is passionate about being a personal trainer.  Do what makes you happy and if you love your job, you’ll never work a day in your life!

Casey spent several years at a “big gym”, before he realized he could do more outside the corporate umbrella.  Therefore he moved on to start Inner Drive Fitness, based out of the world renowned Dudas Fitness. A place where new, healthy, and wonderful lifestyles can begin.

Certifications including ACMS CPT and the Functional Movement Screen (FSM L1), Casey wants to screen, assess, and design the right program for your individual goals and needs while keeping your health and wellness in mind.  We must first move well, then move often.

Exercise and physical activity are only part of the equation for a healthy lifestyle.  Precision Nutrition (PN1) certified, Casey will look at how certain behaviors can be modified to properly balance nutrition to keep you going and the fuel your body needs to recover, thus promoting a healthier lifestyle.  For the most part, if you can’t grow it or kill it, don’t eat it.

We must be prepared for a challenge if we want to see change. As a trainer, Casey will guide you down the path, however the path is yours to create.  The path of a healthier you or the path you have already been on.  You must choose!  Change doesn’t happen over night.  Patience is a virtue that most of us don’t possess. It can be done with the right motivation and will power. It all starts on the inside.

My passion for fitness began in my early 20s. As I experimented with different exercise activities and diets, I learned how my body responded – what worked and what didn’t – and how to safely work back from several surgeries and injuries. 

Over the years, I have been fortunate to learn from my own personal trainers and am excited when I can use my experiences and training to help others be successful.  I have had the opportunity to work with clients ranging from early teens to seniors with different fitness goals. 

I have had the opportunity to work with a variety of clients – from teens to seniors – and with different goals – working back from injuries, preparing for fitness events, losing weight, staying accountable – and in both individual, partner and small group settings.  No matter the client or the situation, I believe it is most important to hear them and create an individualized program.

My philosophy is:

  • Find what works for you…you are an individual and the keys to your success will be different than what works for someone else
  • Learn proper form…you’ll see the best results and mitigate injury when you focus on form
  • Be consistent for long term success…with regular activity and realistic healthy eating

And most importantly in your journey to health and fitness…Do it for you!

Have you ever gotten to the point that enough was enough?

When I got to the point that I was out of breath just from carrying my groceries inside, I realized I was at that point. I was overweight and my overall health was terrible. I looked in the mirror and realized it was time to make a change; I went to the YMCA the very next day and took a BodyPump class. Since that day, I fell in love with fitness and have never looked back. Fitness became more than my lifestyle when I made it my career by becoming the Center Director for Jenny Craig and a BodyPump instructor! Helping others reach their fitness goals became my life’s passion and I eventually began to coach clients 1 on 1. I have experience in endurance, weight loss, corrective exercise, and power-lifting. I’ve also continued to broaden my personal fitness scope as I have spent my last couple of years as a competitive power-lifter and most recently I’ve been working on Olympic lifting. Whether you are looking to lose weight, build muscle, get strong, or simply feel better – I can help you get there. I am 100% dedicated to my clients’ success. When you win, I win!

Why yoga???  Leaving the military after twenty years in great physical shape, I found Martial Arts tended to fill the fitness void. But one day after an annual physical, my doctor told me I had a heart condition and could not continue practicing at the intense levels Martial Arts demanded. In my job as a network engineer, things can get quite stressful on any given day. Without the Martial Arts to “release” that tension, I was feeling the effects with a lot of stiffness in the upper body and needed some practical way to deal with it.

While driving my wife to a class at Jane’s House of Well-Being one evening, I chatted with people attending yoga classes.  They answered my curiosity-based questions and invited me to try a few classes to see for myself.  The yoga style was based in the Hatha Yoga way but also dynamic with movement before stillness. After about two weeks of classes, I noticed I was loosening up.  The more I practiced, the more I was intrigued, by not only the poses and how I was calmly instructed to do them, but how it made me feel about myself.  I entered the 200-hour Yoga Teacher Training at Jane’s for my own yoga growth and graduated in 2017.  When given the opportunity to actually teach my own weekly class, I began teaching at Jane’s that same year.  I went on to teach at other studios and am thrilled to be part of the Dudas Fitness family.

The many people I have had the privilege to share the gift of Yoga with have, like myself, re-discovered themselves in a non-judgmental atmosphere connecting the Mind and Body and Breath. As a teacher, I must understand in my body what I ask of the student so I continue my practice with my teachers as well.

Come to class with a beginner’s mind and find yourself in movement toward stillness.
