Picture of Lynn Criner, DVM 

Sandra "Lynn" Criner, D.V.M. of Missouri City is a veterinarian with Texas Equine & Pet.  After Dr. Criner graduated from TAMU CVM in 1995, her primary focus was on equine medicine and dentistry. As nearly all horse owners have dogs and cats, her practice also evolved to include home health care and wellness for small animals. Over the years Dr. Criner has found that the traditional use of medications and surgery has not always proven 100% beneficial or effective. Dr. Criner's search for a better way led her to Animal Chiropractic care. As a rider and competitor, Dr. Criner is acutely aware of the challenges of keeping a horse in top performance condition.
