NP Sean Dittman began his nursing career in 2003 in San Antonio. Over his 15 plus years of nursing experience, he has spent most of his career in critical care environments like the emergency department and the cardiovascular intensive care unit. In 2012 he decided to pursue advanced practice nursing to serve families in the community. He is now a board certified Family Nurse Practitioner trained in diagnosing and treating the entire family, from infants to geriatrics. Opening his own practice with his wife, Amanda who is a Licensed Vocational Nurse, they wanted to bring quality individualized family care to the community they were raised in. We now have on site laboratory services. Thank you for entrusting us to fulfill all of your family needs and we look forward to servicing this great community!
