Dr Welch in my opinion is a very good Chiropractor -- My adjustment was perfect. My only criticism would be the Intern that also was doing part of the treatment was a novice ineffective and and needed some type of training. Dr. Welch and Diana are friendly professional and effective. However, other than Diana the office was very nonchalant and the office staff were on their cell phones and did not seem engaged in any type of productive office business.
