Born and raised in Maryland, Dr. David W. Jensen attended the University of Maryland, College Park for his undergraduate education. After three years in the Animal Science program, he was accepted into the College of Veterinary Medicine at the University of Florida where his medical interests developed in equine medicine and reproduction. Dr. Jensen obtained his degree of Doctor of Veterinary Medicine in 1982 and along with his family, moved to San Diego county California to complete a surgical and radiology internship at the San Luis Rey Equine Hospital.  From there they moved to the Santa Ynez Valley where he and his wife Karen established San Marcos Equine in 1985 in the heart of the California thoroughbred breeding community. Today, Dr. Jensen maintains a primary care medical practice with a  special clinical interest in OPHTHALMOLOGY, PODIATRY and REPRODUCTION.


Dr. Jensen’s enthusiasm for learning, and his commitment to providing excellent medical care, is fueled through continuing educational seminars both locally within the United States and internationally. Dr. Jensen believes it is a crucial responsibility to his clients, patients and profession to stay informed, participate in studies and further his own education. As a result of this outreach, Dr. Jensen has developed collaborative relationships with an extensive network of experts and colleagues worldwide. These connections give him access to valuable consultation when necessary in order to formulate the best possible outcome for his patients.


Dr. Jensen believes that a strong veterinarian-client-patient relationship is essential for achieving worthwhile equine health goals. Communication is key and clients value his commitment to educating and informing them in all aspects of their horses care and treatment.
