Equine Veterinary Medicine

San Marcos Equine is a veterinary practice serving the equine communities of Santa Barbara and San Luis Obispo counties along the central California coast. Established by David Jensen, DVM in 1985, the focus remains on integrating horsemanship and wisdom with medical excellence for more than 30 years of private practice.

Equine stewardship is an ethic that prescribes the wise and responsible management for the well-being of our patients, the very essence of good horsemanship.  Our goal is to implement this ethic in collaboration with our clients to achieve optimal health for the life of their horses.  We believe excellent medical care and careful management is key in facilitating wellness and peak performance for the athlete, the broodmare or the family pet.

Our practice emphasis is guided by the principle that a focus on prevention and well being is a more powerful tool than treatment in the pursuit of optimal equine health. The personal relationships we nurture with our patients and clients encourages the best decision making in selecting the wisest use of advanced technologies in the diagnosis and treatment of your horse.





Our focus is on wellness, athletic fitness, and optimal performance for your horse.
