Derek Farley, D.O.

Dr. Derek A. Farley is a board-certified family physician with more than two decades of emergency and family medicine experience.  Although he enjoys practicing emergency medicine, his ultimate goal is to build a direct primary care practice and work emergency medicine as a part-time pursuit.  Direct Primary Care is the preferred model for his practice due to the increased availability to the patient by phone, text, email, in-office, or in-home, a better doctor-patient relationship, and the ability to save patient's money while delivering better care.   Dr. Farley currently works part-time at TotalCare ER in Cedar Hill, SurePoint ER in Grand Prairie, and at other hospitals, both local and distant.  He graduated from Ingleside High School, Ingleside, Texas and then went to Texas Lutheran College (now known as Texas Lutheran University).  There Dr. Farley received a B.S in Biology with Pre-Medicine Emphasis, and then he went on to the University of North Texas Health Science Center at Fort Worth.  After receiving his D.O. medical degree in 1997, his family practice internship and residency was at Corpus Christi Medical Center- Bay Area.  He served as Chief Resident from 1999 to 2000, graduating and moving on to be the Medical Director of Plano Minor Emergency Center from 2001 to 2003.  It was during this time he met his wife, Robin (Dees) Farley, PA-C, MPAS.  They have 3 children, twin boys born in 2004 and a daughter born in 2006.  They had a practice, Farley Family Medicine, in Little Elm, Texas from 2004 to 2009.   Dr. Farley sold that practice to pursue Emergency Medicine work, and Robin focused on raising their children.
