Erica Nixon Mack was born and raised in Indiana, and graduated from Indiana University with High Distinction with a Bachelor's Degree in Physical Therapy. Over 20 years as a PT, she has worked in a variety of settings including outpatient clinics, rehab centers, and hospitals across the US. After a start in orthopedics and rehab, her first specialty area of practice was in cardiopulmonary rehab at the University of Michigan Hospital, working with people in critical care, with chronic pulmonary conditions including CF and emphysema, and post operative for cardiac and pulmonary conditions.

Erica spent 6 action packed and fun filled years working part time as physical therapist and part of the year instructing for the North Carolina Outward Bound School, including teaching backpacking, rock climbing, and white water paddling to students from 13-83 years old. Following that, she served as Program Director for Passages Northwest (now part of the Y's Girls Outdoor Leadership Development Program), a strengths-based adventure education program for middle to high school girls.

However, her passion for being a physical therapist prevailed, and after having her own kids and pelvic floor mis-adventures, she returned to practice as physical therapist to specialize in pelvic health and rehabilitation. She completed continuing education through the Herman & Wallace Institute, and passed the inaugural Pelvic Rehabilitation Practitioner Certification exam through Herman & Wallace in February 2014. She continues to serve as teaching assistant for Herman & Wallace Institute for pelvic floor courses. She sees women and men, and has extensive knowledge of the evaluation and treatment of urinary and fecal incontinence, pelvic pain, sexual dysfunction, constipation, pregnancy and post partum conditions, orthopedic dysfunction, and pelvic injuries.

Erica is an active community volunteer, and serves on the Board of Open Arms Perinatal Services, a community based organization in Seattle that supports pregnancy, birth, and early learning with low income families by providing doula support. She also has served on the Risk Management Committee of Bikeworks, as leadership team member of Non-Profit Anti-Racism Coalition, and as volunteer at a Rehabilitation Clinic in Guatemala that provided free care to indigenous children. She has been presenter and published in a variety of topics, including: Treatment of Acute Cardiopulmonary Conditions (in Hillegass & Sadowsky's Essentials of Cardiopulmonary Physical Therapy, 2nd Edition); All-Girls Adventure Programmes: What Are the Benefits? (Journal of Adventure Education and Outdoor Learning Volume 11, Issue 1, 2011); Presenter: Relational Aggression (AEE International Conference, 2008); Co-Presenter: Being a Leader in a Multi-Cultural World (AEE Regional Conference, 2009).

She is active in the outdoors (hiking, climbing, paddling) and part time home schooling her children, loves exercise (running and chopping wood in particular) and keeps busy with various building projects at home.
