Meet the Dynamic Team!

Vince Pitstick - Founder & CEO


I began as a personal trainer in the medical system over 10 years ago. I worked with patients to achieve their fitness goals. Soon I realized the problem was bigger than just diet, workouts, and motivation. The problem was with the lifestyle and the individual. Thus, Nutrition Dynamic was formed where we believe in Reaching Potential Through Nutrition and Lifestyle Change.

Rhya Pachin - Health Coach

Rhya Head Shot.jpg

Through Rhya’s own family's health struggles with autoimmune disease, celiac disease, ADHD, and multiple food sensitivities, she became interested in the power of nutrition as an adjunct therapy to medical treatment. Rhya completed her Bachelor’s in Biology at Wright State University in Dayton, OH; her Master’s Degree in Human Nutrition at Winthrop University; and finally pursued a nutrition license so that she could help others and share what she has learned.

Her primary practice areas are: autoimmune disease, IBS/IBD, PCOS, food sensitivities, and other chronic inflammatory conditions in both adults and children. Rhya has a “functional approach” to nutrition, which means she applies evidence-based nutrition science to support the whole body instead of trying to address a single symptom or system. Rhya is also a certified LEAP therapist dietitian, which means she is trained to design and supervise custom elimination diets.

“Please let me know how I can help you along your journey to optimal health!”

Indeed, Todd has been helping others live a healthy lifestyle for years, knowing early in his personal training career that just working out was not enough to solve the complex health issues people are facing. He has since been expanding his understanding of other important factors like nutrition, stress management, sleep, and community.

Brennan Kerchner
Department Assistance & Director of Sales
Brennan Pic Edit 5.jpg
Brennan Kerchner is new to the Nutrition Dynamic Team as of July. He will be working in tandem with all departments within the company to help and grow in any way that he can.
Brennan’s interest in fitness, health and supplementation started when he was 13 years old. He wanted to get bigger, faster and stronger for competitive travel hockey and knew training and eating would help get him there. After he caught the bug; training, eating and supplementation soon became his new love.
He has been involved with the industry since he was old enough to work. Jobs were either in a supplement stores, health food setting, personal training and online coaching. He is also a competitor and has done shows in the Men’s Physique division and will be transitioning to Classic Physique in the 2019 season.
Brennan then tried to veer off and go the corporate route and take a job that was not fitness related and he soon realized that he could not step away from where his true passions were. That is what lead him to teaming up with Nutrition Dynamic, along with Nuethix Formulations.
