Certified Fitness Trainers

ERICA MITTENDORFF, Personal Trainer Specialist

Erica’s journey of wellness started in college where she became immersed in hot yoga. Yoga became a way of life that allowed Erica to find ways to connect the mind and body. Shortly after graduating from college, she became a registered yoga teacher. Her love of wellness grew beyond yoga after working in a corporate setting for 7 years. When the pandemic hit, she was furloughed from her job and wasn’t sure if she would be returning to it. Therefore, Erica started focusing on her physical strength and then her desire grew to become a personal trainer. From there Erica has earned several certifications from Barre, Pilates, Gait Analysis, and more. After going back to her corporate job for 6 months, Erica took the leap and decided to become a full-time instructor/personal trainer. She specializes in senior fitness and enjoys showing her clients new and more efficient ways to train. Erica’s personal passions include running in races, practicing mindfulness, and spending time with her children.

Erica's training approach is focused on overall health and wellness, and she takes the time to understand my unique circumstances, adapting my workouts accordingly. As a result, I have made significant progress and improvements in my overall fitness.

- Anna.

“I had always been hesitant to invest in a personal trainer... it seemed like a frivolous luxury since, as an MD, I should know what to do, and besides, I used the elliptical and walked regularly. But I was getting bored and needed new input, especially on managing arthritis and other “aging” issues. After my first assessment visit with Rebecca, I felt like she really listened and observed, and understood my goal for general health maintenance and control, a general sense of well-being, and the ability to independently make corrections when something starts to hurt. I’ve been out of the country for a month now and can’t wait to get back into our routine...I always feel great and stand taller after our sessions!”

- R.E. Hanson, MD
