John Lyman Horn, 52, of Lone Oak, passed away on September 2, 2018 at the Hunt Regional Medical Center.  A memorial service will be held on Friday, September 7, 2018 at 11:00 a.m. at Wesley United Methodist Church with Rev. Chris Yost, Mr. Jim Latham and Mr. Brian Alford officiating.  Services are under the direction of Coker-Mathews Funeral Home.


John was born January 6, 1966 in California to Bill and Sharon Rilea Horn.  On April 5, 1997 in Ft. Worth, Texas he married Julie Twyman.  John served as a Judge for Hunt County.  He was a 32nd Degree Mason with the Greenville and Lone Oak lodges.  He attended Wesley United Methodist Church.


Judge Horn is a graduate of Texas Tech University and holds a Masters Degree in Business Administration from LeTourneau University.  In addition to his formal education, Judge Horn also holds a Master Peace Officer Certificate through the Texas Commission on Law Enforcement.


John and his wife left their home in Colleyville, Texas to establish a new business opportunity in Greenville. John and his wife opened Kwik Kar Lube and Tune back in 2000 and soon after built the Kwik Kar Auto Spa.  Both businesses were very successful and were sold to corporate investors in 2003.  In addition to his law enforcement background, John’s business experience spans from manufacturing and wholesale distribution to commercial and residential construction.


After serving for almost four years with the Hunt County Sheriff’s Office, John was elected to the office of County Judge in January of 2007.  Judge Horn was a 2007 graduate of “Leadership Hunt County” and currently serves on the Leadership Advisory Committee and Executive Board for Hunt County Agriculture Extension Co-op.  Judge Horn was a former appointee to the Texas Association of Counties Risk Management Pool Board and Executive Board as well as an Executive Board Member of the North East Texas Rural Transportation District (NETEX), Committee Member for the North Central Texas Housing Authority, Committee Member for South Sulphur Regional Development Association, Ex-Officio to Greenville Chamber of Commerce and Current Regional President of the CEO’s of Workforce Solutions D/FW Region.  John was a member of Greenville Lions Club, Dallas Scottish Rite and Past Master Greenville Masonic Lodge 335 AF & AM.  In 2009 John was nominated to serve as President of the Executive Committee of the North Central Texas Council of Governments.  He also served as the Chairman of the Regional 9-1-1 Advisory Committee.  John was also the past President of the Hunt County Alliance for Economic Development.



In 2009 Judge Horn was a leading factor in the development of the first Hunt County Transportation Plan.  Working in conjunction with staff from the North Central Texas Council of Governments, John presented the first plan of its kind in Hunt County.  He has also served for the past several years on the Regional Transportation Commission, representing both Hunt and Rockwall Counties.  Under Judge Horn’s leadership Hunt County now has a county wide transportation committee comprised of representation of all major cities and other related entities within the county.  Horn collaborated with partners to manage the first Hunt County Transportation Implementation Plan that is opening doors for future access to funding opportunities at the State and local levels.  John truly believed that transportation is the key to economic vitality to the region.


John looked not only at the needs of Hunt County, but also how growth in and from the Metroplex would impact Hunt County in years to come.  The most important part of that was planning for the transportation needs of Hunt County as the population growth moved from the west.  John organized a 25-member Steering Committee of citizens from around Hunt County to work with the North Central Texas Council of Governments over a three-year period to develop a transportation and land use master plan.  The plan was endorsed by every city in Hunt County and adopted by the Commissioners’ Court in 2013.


Not to allow the plan to gather dust, John then organized a second Steering Committee that represents the citizens of Hunt County to implement the transportation portions of the master plan.  Over the next 18 months, the Steering Committee and its supporting professionals put together the Hunt County Transportation Bond Program that was presented to the voters in November 2016 and approved by an overwhelming majority of taxpayers.  That program of $24.2 million in local funding has now generated commitments in excess of $200 million in state and federal funding for construction of the projects that will provide both safety and additional capacity as Hunt County experiences additional growth.  John was dedicated to the proposition that managing growth was one of the most important priorities for the Hunt County Commissioners’ Court.


John is survived by his wife, Julie Horn of Lone Oak; parents, Bill and Sharon Horn of Yantis; sons, Chase Horn of Greenville, Tyler Duffy of McKinney; granddaughter, Hayden Horn of Greenville; sister, Stacey Luster and husband, Randy of Grapevine; mother-in-law, Lou Ann Twyman, Lone Oak; brothers-in-law, Jeff Twyman & wife, Jennifer of Louisville, KY, Steve Twyman, Lone Oak; niece, Harper Twyman of Louisville, KY; nephew, Duncan Twyman of Denver; and numerous aunts, uncles and friends.


He is preceded in death by grandparents, John Paul and Bea Marshall.
