OUR TRAINERS


Jackie Sanca, Lead Trainer

I have had the pleasure of being a trainer at AHFC since their doors opened. Holding a BS in Speech and Language Pathology and a Masters in Exercise Science, Physical Education and Health, I’m currently working as an elementary PE/Health Teacher. My passion is to make physical activity, movement and health available and attainable for all. My hobbies include walks and hikes with my dog Calvin, and cooking and spending time with friends and family. I played rugby in college and enjoy recreational sports now. My inspiration for working here at the fitness center is watching clients grow and be able to attain goals they never thought they would. There is a sense of community; everyone who walks into the facility belongs and will achieve goals that will set them up for a life full of health and wellness.

Umberto Posca,  Trainer

A former pre school teacher and behavior therapist, I am an ISSA certified trainer and have a lot of experience working with troubled youth and children of different ages on the spectrum. A Trainer at AHFC for 2 years, I enjoy working here because I love fitness and having a positive influence on people’s days and lives, especially those who find it hard to be understood, work out in public, and build relationships with people other than family. It is my goal to have everyone smiling as they leave the gym after a session with me. Some personal background on me: I am a former high school and collegiate athlete, basketball is a constant in my life and I love almost every other sport.. Big Eagles fan so catch me on Sunday watching the birds! I also enjoy watching great TV shows and movies and discussing them with friends. 

Nadia Wilson, Trainer

I am a graduate student studying speech-language pathology. I have experience in a public school and a specialized school. I have served as a one-on-one paraprofessional and hope to continue working in an educational setting. Here at AHFC, I started an inclusive track team, which I enjoy being a part of. Helping my clients enjoy exercising and finding preferred methods of staying active has inspired me at the gym and beyond. Outside of work, I love staying active by running, biking, hiking, and doing yoga. When I am not exercising, I love traveling and trying new foods. I am CPR and NASM-CPT certified.
