Medical Administrative Assistant
Gae has always been passionate about nutrition and fitness. She spent many years working in a physical therapy office and an athletic club where she learned the latest and greatest information on health.
Gae's journey into alternative medicine began a few years ago when she was diagnosed with an autoimmune disease. She was surprised when she became ill because she had faithfully followed all the advice from the experts. Traditional doctors tried to help, but finally said there was nothing more they could do. This is when she discovered Functional Medicine and all that it had to offer. It has turned her life around!
As the Director of Operations at the Healing Collective, Gae strives to create a positive, nurturing, and happy environment. She will answer your questions about the practice, help you set up appointments, and promote efficiency in the office to respect you and your time.
When she's not at the office, Gae enjoys playing African drums and practicing Tai Chi.
