Dr. Jeff Kosoris moved to Waxahachie and opened his office in 1982 after graduating from Baylor College of Dentistry near the top of his class in 1981 and working with a dental practice in Dallas for a year.   Within a few years he had earned Fellowship status in the Academy of General Dentistry (FAGD) and completed the curriculum at the Pankey Institute for Advanced Dental Education in Florida.  Every year he attends numerous continuing education courses and after completing the Advanced Restorative Series and Masters Series of the Center for Aesthetic and Restorative Dentistry in Dallas, has become a member of the Teaching Faculty there.  He has twice served as President of the Sixth District Dental Society and held numerous other positions, has been a delegate to the Texas Dental Association policy meetings, and is a member of the American Dental Association. 

He has been voted by his peers in an annual survey to the Texas Monthly Super Dentist listing in 2008, 2009, 2010, 2011 and 2012 in the general dentistry and cosmetic dentistry categories.


Dr Kosoris is married to the former Susan Schliep of Waxahachie and has raised 3 sons, Justin, Kevin, and Daryl (“D.J.”). Susan has been a part of the practice for many years working at the business and IT side of the practice, and the boys have helped out there a bit over the years but none, it appears, will be following in their father’s footsteps into dentistry. Justin is a graduate of Johns Hopkins University and earned a masters degree at the LBJ School of Public Affairs at UT Austin, with a two year stint in the Peace Corps in Senegal, Africa, in between schools. He lives and works in Washington, D.C., traveling often as his work takes him overseas regularly. Kevin is a practicing lawyer in Waxahachie at the firm of Willett, Wray, and Stouffer.  He  attended law school at SMU in Dallas after graduating from the College of William and Mary in Williamsburg, Va. He is married to the former Samantha Meade of Waxahachie who teaches kindergarten at Northside Elementary in Waxahachie. DJ attends Navarro College in Waxahachie and works full time as an Insurance Account Representative for the State Farm Insurance agency of Steve Boulton here in Waxahachie. Susan is very active in local civic endeavors, serving for many years on the Board of the SPCA, Junior League, Symphony Association, the YMCA, and is active in several local clubs and charitable causes. Dr. Jeff volunteers at The Ellis County SPCA, Hope Clinic, Waxahachie Lions Club & Historic Waxahachie. He spends his spare time with family, vacationing and enjoys art, basketball, tennis and bicycling.



Since moving to Waxahachie, Dr Kosoris has been a very active member of the community. He has been a longstanding member of the local Lions Club, having held nearly every position including President and served on its Board for many years. He is a past volunteer and Board member of the Waxahachie Symphony Association, has volunteered as a fundraiser for the YMCA, and helps to support many causes as a member, volunteer, or sponsor for local events and organizations. He is most proud, though, of balancing work with family time, having coached over 50 athletic teams for his sons, ranging from soccer, baseball, football, and basketball over the years in various leagues.

Hope Clinic:

In 2000, Dr Kosoris helped start the Hope Clinic in Waxahachie, a facility for medical and dental treatment for the indigent and medically underserved population of Ellis County. After serving as a volunteer dentist for several years, he joined the Governing Board and is currently serving his second term, having been voted Board President during his first term on the Board, a position he presently maintains.  The Clinic has grown tremendously and has become a major health care facility in Ellis County. He counts his involvement with Hope Clinic as one of the most meaningful experiences of his life. Dr. Kosoris recently capped a longstanding effort to expand the Clinic into Ennis by signing the papers to acquire a medical office building for conversion to the Hope Clinic of Ennis location.  This much-needed expansion into eastern Ellis County has been well received by the citizens of Ennis who have offered widespread community support.
