Along the way, she has continued her training in manual therapy including cranial, visceral and functional techniques.

While her background is in orthopedics, joint pain and treating a range of patients from post-surgical to geriatric, she felt compelled to explore more complex and ultimately more effective methods of treatment. That is what led her to Manual Edge Physiotherapy.
