Larissa Twinem

Registered Massage Therapist

Larissa has had a passion for massage therapy ever since pushing on her mother’s trigger points at age 6 to relieve her tension headaches. This passion developed more through high school when Larissa joined a competitive swim team and started taking training seriously. The intense workouts resulted in many sport related injuries which Larissa would treat by coaching her 12 year old sister through a “massage treatment”. Growing up in a third world country (Peru, South America) meant that alternative medicine of this form was not a popular option. Larissa, having experienced the benefits of this form of manual therapy, was determined to develop the art of aiding the body in the healing process. She wanted others to be able to experience the relief that massage therapy provided.

This determination lead her back to Canada where she attended the Canadian College of Massage and Hydrotherapy. It was here that Larissa’s fascination with science, the human anatomy, as well as her desire to help people merged. She graduated with honours completing extensive hours of clinical practice and outreaches that put her in both sport and hospital settings.

Larissa is a Registered Massage Therapist with College of Massage Therapists of Ontario and is proud to be joining the team at Peak Performance Health Centre.

Taylor Smith

Registered Massage Therapist

With hard work and dedication Taylor graduated from the Canadian College of Massage and Hydrotherapy in 2017 earning her diploma with Honours. Taylor is a member of the College of Massage Therapists of Ontario in good standing.

Taylor’s passion for Massage Therapy began at a young age when dealing with many different sports related injuries. Growing up with three older brothers Taylor was always taught to be tough and never let her injuries get in the way of her soccer games or her track events. This motivation is what pushed her to seek help from a multi-disciplinary setting to keep her healthy on and off the field. She soon realized the benefits of manual therapy and found herself wanting to work in a field that was able to help others.

Since graduation Taylor has been working at Peak Performance Health Centre and is dedicated to putting her clients goals and health first. Taylor enjoys working alongside her colleagues to help her learn the best possible treatments for her clients. Taylor is excited to expand her knowledge and continue learning on her new path in order to help bring her clients to their peak performance.
