"My enjoyment in assisting patients back to doing what they love to do day-to-day led me to furthering my expertise into Personal Training, Corrective Exercise, and Women’s Fitness. Personal training allows me to reach a greater range of people of all ages, work with clients post recovery stages of injury, and most importantly share my enthusiasm and knowledge in helping them move beyond their boundaries and recognize new potentials not initially realized!"
