OWNER AND FOUNDER

COACH CRIS MCCULLEN

Senior Exercise Specialist

I am the founder of Ameristrength Fitness. As a kid, sports and physical activity were my life. I started getting into resistance training when I was 16 and I fell in love with powerlifting, bodybuilding and nutrition. In fact, I loved it so much that I went to school and got my bachelors in Exercise Science. I wanted to pursue physical therapy, but the family took precedence. I switched careers and became a firefighter paramedic which I enjoyed, but found was not my passion. However, it gave me the priceless experience to become my grandmother’s in-home nurse for the last seven months of her life. After her death, I knew I had to get back to what God put me on this earth to do. These are the pillars Ameristrength Fitness was built on.

  • Bachelor of exercise science
  • Certified personal trainer
  • ACE certified nutrition coach
  • Senior Health Wellness Specialist
  • CPR and First Aid certified
  • Paramedic and medical expertise

FOUNDER AND BUSINESS
MANAGER

Christina Feo McCullen

I’m Christina My mission, under God, is to empower and change lives through movement. My specialized niche is working with kids. I just love to motivate others through music, dance and movement! I have a minor in dance and psychology and a law degree. Have been blessed to teach a variety of modalities from Mercy Hospital, to high end luxury condominiums, afterschool programs, dance studios, assisted-living facilities and daycare.
I have taught:

  • HIIT training
  • ZUMBA
  • Cardio Kickboxing
  • Self defense
  • and Kids dance, including
  • ballet, lyrical, hip-hop, and movement

I've had more than a dozen personal trainers over the years, and Cris is by far the best. People have asked why with my years of experience I would pay for a trainer. The freshness of the variety of workouts, the encouragement to pursue goals, and the prevention of injuries through maintenance of proper form and avoidance of excessive weights make the sessions something I look forward to.
