Dr. Lutz K.G. Harfst

~Veterinarian, Owner~

Dr. Harfst has been providing excellent veterinary care to the communities of the Yakima Valley for more then 15 years. He has upheld a strong commitment to bringing quality care at affordable prices to our area. Part of his commitment to quality and value is carried over from our practices foundation as the Yakima Spay and Neuter clinic. Dr. Harfst takes a special interest in equine medicine and worked in some of the top jumper and dressage barns in Europe before making the move back to the Yakima Valley. When he is not at the clinic or on a farm call you are most likely to find Dr. Harfst spending time with his wife and children at their farm Marble Hills Stables.
