Sharon Costello - Certified STOTT PILATES® Instructor

Sharon Costello is a STOTT PILATES® Certified Instructor. She began her fitness career in 1999 teaching Mat, Reformer, Cadillac, Chair, and Barrels at a local club. Her clients range from rehab to serious athletes.

“The goal is to be strong yet mobile,” Sharon says. “I believe Pilates will absolutely benefit everyone. It should be challenging yet enjoyable!”

Sharon’s love of Pilates grew after only a few sessions as a participant.

“I lifted weights for years yet couldn’t believe how strong I felt after Pilates,” Sharon said. “Not only did I feel strong, but I was also standing taller and felt wonderful.”

Sharon has been living in Claremont for over 20 years. She is married and has 2 children.

Certifications include STOTT PILATES®, Pilates Physical Mind Institute, Cycling, and Bosu Balance Training.

“Sharon is just amazing. Training with her has been an outstanding, priceless, and life-changing experience. After going through a tough divorce and having scoliosis my body and spirit were very weak. Her love for Pilates, talent, knowledge, patience, care, compassion, loyalty, encouragement, and expertise was essential for my recovery. She has made me so much stronger and healthier than ever. She motivated me to get STOTT PILATES® certified and now I teach at one of Americas Healthiest Clubs in a 5 star Community in Naples, Florida! I feel truly blessed to have found Sharon in my journey. I will be always thankful for what she has done for me. I miss her every day.” —Pamela
