Dr. Mark J. Weimer is a fourth generation California native. Born and raised in Northern California, he spent a lot of time on the family ranch in San Joaquin Valley. By age seven, he was assisting his veterinarian uncle with spays and neuters of farm cats. His compassion for animals and willingness to learn had launched, headed for a career in veterinary medicine.
Mark graduated from University of Southern California with a Bachelor of Science degree in Molecular Biology. He then ventured southeast, his first time ever east of Virginia City, Nevada and graduated summa cum laude from the University of Tennessee College of Veterinary Medicine.
As a new veterinarian, he returned to California. He was an associate at animal hospitals in Carmel, Chatsworth, Big Bear and Long Beach.
