"Dr Harris has chosen to work with one of the most difficult population of patients around-combat Veteran’s. But with 44 years of experience, he manages to stay in control of the session and seems to always stay focused with a laser-like accuracy. Dr Harris understands what the Vet is saying and what they are not saying, and is quite adept at providing relevant resources, such as books and social resources and contacts. Dr Harris is very skilled in addressing the myriad aspects, other than just the military, of the client’s life. Dr Harris is a prized clinician and one of the best."

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
