Evaluation of a provider can start before you meet the provider. The way staff treats you often reflects the way a provider will treat you. If you really want to see providers who are not taking any new patients, don't give up. Sometimes you can get on a waiting list. Age and number of years in practice are also considerations when looking for a provider, although these should not be the primary considerations.
Some people are comfortable with providers who are older and have been practicing for many years.
People sometimes believe providers who have been in practice the longest are the most qualified. This is not always true. Some providers who have been in practice for many years may have a tendency to be less medically current. After a certain age, some providers may not pursue new information as often as they used to. There are always exceptions.
