Dr. Samuel D. Critides
Dr. Critides served in the United States Navy for 20 years. After serving as a battalion surgeon with the United States Marines, he was selected for training as a neurosurgeon. He then served the remainder of his career in the Navy as a neurosurgeon, including tours at National Naval Medical Center Bethesda, Naval Medical Center Portsmouth and Wounded Warrior Regiment in Quantico, Virginia.

He deployed as the spine surgeon on the USNS Comfort, the forward deployed mobile Naval Hospital Ship, where he provided care for victims of the Haiti earthquake in 2010. After his time in the Navy, Dr. Critides wanted to help to continue to serve our military community, so Homeport Neurosurgery was created. Since 2021, Dr. Critides has returned to the beautiful Emerald Coast, choosing to serve his local community as well as active duty and retired service members. In his spare time, Dr. Critides stays active with cross fit and running. He enjoys spending time with his wife, Maricarmen, their four children, and his dogs.
