I am an (retired) RN so am always hyper aware of the quality of my medical care. Dr. Tsongalis treated me with the utmost respect and compassion.

He went out of his way to pull up an old x-ray of my neck and review it with me. Made suggestions about discussing his thoughts at my follow up with Dr. [redacted].
