    He is not my primary doctor, but I needed a follow up appointment after going to an ER over the holidays. He got me in quickly, and I really appreciated that and the way he assessed my health. He added an additional test, and that was important.. he was very thoughtful, and answered my questions.

    Feel that Dr. Bell is marking time to his Retirement and is bound by policy of time limits Per visit. Physicians are in a bind sometimes due to corporate policies not always in the interests of the patient.
