Welcome to Advanced Veterinary Care of San Elijo.  We have been helping the pets and people of San Marcos and beyond since 2014.  We built our 2400 square foot, state-of-the art facility with the goal of providing this pet loving community with superior, high-quality, compassionate veterinary care.  From our facility, to our services, to the staff that we hire, our mission is evident in every aspect of our clinic.

Our mission is to provide quality, advanced veterinary services in a warm, honest, and compassionate atmosphere”

Dr. Sunshine Riehl and Dr. Paula Thomas veterinarian owners of Advanced Veterinary Care of San Elijo

Our practice owners, Dr. Sunshine Riehl and Dr. Paula Thomas are passionate lifetime animal lovers with roots in emergency medicine.  After years working in emergency and specialty veterinary practices these longtime friends saw a need for a general practice that provided excellent, honest, modern medicine in a friendly “community veterinary clinic” environment. 

Essential to any exceptional hospital is an exceptional staff.  We strive to hire and support outstanding Associate Veterinarians, Registered Veterinary Technicians, Veterinary Assistants, Customer Support Representatives, and Kennel Assistants.  Each of our staff members are smart, well trained, and experienced, while having outstanding compassion for pets and their people.  Our staff are all pet lovers and pet owners, and it shows in their compassion and caring for each of our patients and their families.

Our hospital provides a range of services from wellness care, to injury and illness intervention, to emergency services.  To help keep your pets healthy and happy, we provide exceptional wellness services.  These include wellness exams, quality vaccination services, puppy and kitten packages, and senior wellness care.  When your pet needs help with an illness, disease, or injury we are there to provide up to date care, as well.  We offer advanced laboratory services, X-ray, surgical services, ultrasound, palliative care, and pain management.  Finally, in the event an emergency arises we provide daytime emergency services to help your pet in a comfortable, familiar environment.

We genuinely believe that our facility, services, and staff are among the best in San Diego County.  We treat each pet like our own and each client like family.  Come and meet us and see for yourself.  You will be glad that you did!
