About Us


 Colleen Blanchfield, M.D.

Dr. Colleen Blanchfield earned her Bachelor of Science from the University of Wisconsin in 1981 with majors in Zoology and an independent major entitled Biology and Psychology of Women. After finishing her residencies in Neurology and Psychiatry at State University Health Science Center in Brooklyn, Dr. Blanchfield chose to begin her neuropsychiatric practice in Northern Virginia. She was attracted to the diversity of the area as well as the strong sense of family and community that she found here.

She had a successful Neuropsychiatric practice in Falls Church from 1992 to 2004. She was on staff at Dominion Hospital and Fairfax Hospital and performed electroconvulsive therapy at both hospitals. She has a life-long interest in the brain, behavior and mind-body connections. She has opened this wellness center with the intent of expanding her knowledge and her ability to help people help themselves. She moved her practice to Reston in early 2004 for personal as well as professional reasons. In both Neurology and Psychiatry, Dr. Blanchfield provides clinical assessment and evaluation as well as medication management. She is licensed to practice acupuncture in Virginia. She is married to another Washington-area physician and is the mother of two sons.

Dr. Blanchfield is fortunate to work with a staff of passionate mind-body practitioners who share a common vision of wellness.  Their input and collaboration are essential to comprehensive patient care.
