Dr. Hillery was born and raised in Enid, Oklahoma and spent his early years in the Midland area.  After graduating from medical school he completed his residency in Dallas and moved to the Houston area where he worked for several years in the Texas Medical Center.  His desire to raise a family in a close knit community landed him in the Richmond/Rosenberg area where he has spent the last 25 years serving the people of the surrounding areas.  Dr. Hillery has been married to his wife Elizabeth for over 30 years. She is a registered nurse and works along side him in the operating room.  Dr. Hillery enjoys playing the piano and guitar, listening to a wide array of music from classical to rock n roll, and enjoys playing a few holes of golf when he can get away.  Dr. Hillery and Elizabeth have 4 children.
