Karen J. Metzler, D.V.M.

Dr. Metzler was fortunate to grow up in a home filled with a wide variety of family pets, including hamsters, birds, cats, dogs, and horses. She has always loved animals, so it was only natural for her to choose veterinary medicine as her career path. She graduated from Texas A&M’s College of Veterinary Medicine in 1997. She has experience in both emergency medicine and general practice. She has specific interests in surgery, dentistry, internal medicine, exotics, and cardiology. Dr. Metzler is dedicated to both her profession and her family.

She, her husband, Jeff, and their six children, Daniel, Brandon, Madison, Meridythe, Maycie, and Noah, live in Bowie, Texas. They enjoy the country life as it supports the many family pets and farm animals they care for and love.
