Our Veterinarians

Timothy Van Geem, DVM, PhD/Owner

Dr. Tim Van Geem graduated from Kansas State Veterinary College in 1987. Dr. Van Geem has a Master of Science in Biology and PhD in veterinary/medical entomology but he became frustrated with research and followed his dreams, returning to veterinary school. After graduation, he completed an internship in surgery in Las Vegas.

Dr. Van Geem practiced in the San Francisco area for six years, dividing his time between general practice and critical care. During that period, he developed a special interest in dentistry and surgery. He purchased Mother Lode Veterinary Hospital in 1994, and for the next five years he also provided referral dentistry services for Loomis Basin Veterinary Hospital, splitting his time between the two facilities. He has been a member of the American Veterinary Dental Society since 1994 and continues to provide advanced veterinary dentistry for pets.

He enjoys cycling and scuba diving and has spent many years developing his interest in sculpture. Dr. Van Geem’s wife, Erin, is the co-owner and practice manager of Mother Lode Veterinary Hospital.  They have three sons: Josh, is currently a veterinary student at UC Davis; his twin brother Brody just completed a degree in economics at Oregon State University; and the youngest son, Cavan, is an anthropology major at the University of Nevada, Reno.
