Dr. Patti S. Maness: Dr. Maness knew at a young age that she wanted to be a veterinarian. She started  at the age of 15 as kennel help at a veterinary clinic in Ralston, Nebraska. Dr. Maness attended Texas A& M University in College Station, Texas, where she was an active member of the Texas Aggie Corps of Cadets while pursuing her undergraduate degree in biochemistry.  She graduated magna cum laude with a Doctorate of Veterinary Medicine in 1981.

Her practice career began in Weslaco, Texas just five miles from the Mexico border where she learned to speak "Tex Mex" and work on cattle. The next career move was to San Antonio, Texas where she made her practice home for the next 16 years. Dr. Maness began as an associate and was the owner of one of the biggest clinics in San Antonio at that time with five doctors and a large support staff. This enabled her to concentrate on her love of surgery and often performed 6 to 12 procedures daily. This clinic partnered with another clinic and established the first Animal Emergency after hours hospital on the southside of San Antonio.  This emergency clinic eventually merged with her day practice to become a 24 hour 7 days a week veterinary care facility. 

Snow in Okla with casias Kids, Jasmine and DevinDr. Maness married her husband, Rudy Casias, in 1999. Her only "son", Jasper, was four legged and furry; and carried the rings in the wedding.  When Kelly AFB closed, Rudy was transferred to Tinker AFB in Oklahoma. They bought a home in Newcastle, Oklahoma big enough for all their pets.  Dr. Maness commuted for the next few years and also worked the Animal Emergency Hospital of North Texas in the DFW area. This is an emergency and critical care hospital as well as sharing the facility with a surgery referral center.  Rudy and Patti became certified foster parents for the State of Oklahoma and have had many children through their home. Rudy was deployed to Kuwait for 5 months, and Patti elected to practice full time in Oklahoma to help care for their burgeoning two and four legged family. Rudy is still an active duty Air Force reservist as well as full time civil servant at Tinker AFB. They are up to three adopted children now. Raising and showing alpacas, managing their horse herd and pet Longhorn cattle as well as selling farm fresh eggs keeps their family busy.  Both Patti and Rudy are still very involved in the local community where Patti was a Girl Scout Leader for several years, and Rudy is on the Newcastle Local Planning Advisory Committee and the Newcastle Education Foundation.  Both Patti and Rudy participated in the Newcastle Visioning Process. Dr. Maness is a member of the Newcastle Chamber of Commerce and has been on the Executive Board, as well as a board member.  Maness Veterinary Services founded and has sponsored the annual
Newcastle Pumpkin Fest's Pet Costume Contest for many years. Since 2014, Maness Veterinary Services also sponsors the Purple Color Station at the Newcastle Racer Dye Run; a chamber fundraiser with part of the
proceeds sent to a designated charity each year.

Dr. Maness is dual licensed in Texas and Oklahoma. She is a believer in continuing to develop practice skills and keeping up with the advances in veterinary medicine. She is a member of the American Veterinary Medical Association (AVMA), a lifetime member of the Texas Veterinary Medical Association (TVMA), the Oklahoma Veterinary Medical Association (OVMA), the Central Oklahoma Veterinary Medical Association (COVMA), Veterinary Emergency and Critical Care Society (VECCS), Veterinary Information Network (VIN), International Veterinary Ultrasound Society (IVUSS), and the Society of  Aquatic Veterinary Medicine (SAVM).
