Randy Langerhans, DVMdrlangerhans-1

After 35 years Dr. Randy Langerhans relocated his practice from west Ft. Worth to this location on I-20 in Hudson Oaks, TX (just east of Weatherford, TX) in September 2010. He began practicing in west Ft. Worth in 1975 after graduating from Texas A&M University College of Veterinary Medicine. Soon after graduation he was a charter member of the Ft. Worth Small Animal Emergency Clinic with 21 other veterinarians. He worked as a emergency clinician as well as practicing general medicine and surgery at his own veterinary practice. During the 1980's he and his two partners owned and operated 5 veterinary practices in Tarrant County. In 1991 after the partnership was dissolved he then owned and operated Ridgmar Animal Hospital which he developed into a 24-hour animal hospital in 1992. In 1997 Dr. Langerhans changed the name to Ft. Worth Animal Medical Center which was sold to VCA corporation in 1998. He remained with VCA as medical director and continued to practice there until July of 2010. At that time Dr. Langerhans decided to relocate his practice and establish I-20 Animal Hospital.  In 2021 he sold I-20 Animal Hospital to NVA where he continues to work and care for his clientele.

He takes pride in staying current with veterinary medicine and recognizing the magic bond that people have with their pets. Through the years Dr. Langerhans has developed expertise in many areas of this wonderful profession. His special interests are in surgery (soft tissue and orthopedic), emergency and critical care, internal medicine, and oncology. Dr. Langerhans has always felt that pet owners should have similar options as they themselves do for their pet's emergencies and hospitalization for various conditions requiring 24 hour care-- thus creating another 24/7 full service animal hospital.

Through the years Dr. Langerhans has served as an officer with the Tarrant County Veterinary Medical Association and as a director on the Board of Directors of the Texas Veterinary Medical Association. He and his wife have two adult children and three grandchildren. They also have Ranger (German Shorthair Pointer) and Rocky (Bassett Hound) at home. He is looking forward to continue practicing but just in a different location.
