I have been a physical therapist since 1975, working in home health, long-term care, acute hospitals, rehabilitation departments and outpatient clinics. I opened a private practice in Washington, D.C. in 1981 and continue to work as a clinician, specializing in prevention, wellness, and functional fitness for adults.

My passion lies in the area of rehabilitation and optimal aging, and I have published extensively in a variety of journals and authored numerous textbooks on aging. I have served as Editor-in-Chief of an award-winning international journal for over 30 years, have lectured extensively across the U.S. and worldwide, and have received numerous awards from both local and international organizations. 

I currently see clients and serve on the Medical Faculty at George Washington University as an adjunct professor in the Department of Geriatrics. In an ongoing effort to further serve the profession, I volunteer for many local and national offices and have served as the president of both the DC chapter and the Section on Geriatrics of the American Physical Therapy Association.

I love to throw parties and read well-written fiction. I also love to read everything I can on exercise and aging.

Age does not matter unless you are a cheese.
