Owner + Personal Trainer
SHELLEY CLARK
I have always been passionate about the fitness industry and have been on my personal fitness journey for over 30 years. I enjoy strength training, yoga, Pilates and hiking. After being a stay-at-home mom to my two daughters for many years, I made the decision to share my passion for fitness with others. I began by obtaining my Bachelor’s Degree in Sport Management with a concentration in Wellness and Fitness and then becoming a NASM Certified Personal Trainer.
I maintain my certification by attending fitness conferences and continually learning new modalities through classes and training seminars.
I enjoy training clients of all ages and abilities. My objective is to help you determine, set and achieve your individual goals- whether it is building muscle, losing weight or just trying to live a healthier life. Your program design will be created specifically for you and your needs in mind.
I offer personal training and small group training.

KEVIN PROSCHOLD
My journey of becoming a personal trainer began at a very early age. I played every sport imaginable throughout my childhood, and that created a passion and drive within me for the human body and fitness. I was granted a soccer scholarship as a Division II NCAA athlete which allowed me to pursue my dream of attending and graduating college with a degree in Kinesiology from California State University at Monterey Bay. The combination of my education and athletic history molded me into the personal trainer I am today.
I offer personal training, small group training and TRX classes.
During your fitness consultation we will develop a program based around one or more of your fitness goals, whether you want to gain strength, lose weight, increase your sports performance or recover from an injury. We will work together and strive for greatness every day!
