Dr Johnston carefully and meticulously reviewed my brother's past and recent history. He asked questions as he proceeded and patiently waited for a response. He offered us alternatives to an angiogram that we felt would be dangerous under the present circumstances without current symptomology. He explained each of the procedures and graciously accepted our choice.

Dr. Johnston is a gifted clinician- thoughtful, compassionate, caring, and very knowledgeable. When he retires, the Hopkins community will have lost a valuable contributor to the health of our community.

Dr Johnston always seeks my best concerning medical care. For example he ordered blood work to determine if my toe pain may be due to high Uric acid or gout.

Dr Johnston coordinated with my PCP and then ordered blood work for both of them. When the results came back, he called and coordinated a repeat of a faulty lab result to be done at Johns Hopkins. He showed great concern for my health.
