My father-In-law sees Dr. Zak. I referred him on the excellent recommendation of my friend, a nurse practitioner, whose father was treated by him. My husband has accompanied his dad on a few appointments and was impressed by his thoroughness and professionalism. He spends a lot of time with his patients and obviously really cares about what he does for people. He even takes his own vital signs. You always see just Dr. Zak, he works alone which is rare nowadays. Highly recommended.
