Dr. Issacson was everything I was looking for in a family doctor. He knew what was in my health records and treated me like I was his only patient of the day. I never felt rushed and he explained everything in detail about my health plan going forward. Dr. Issacson was engaged and personable. I feel blessed having Dr. Issacson as my health care provider.
