Patients are seen by appointment. Consultation appointments may be made by your veterinarian or yourself, with one half hour being allotted for an initial evaluation. Please let us know as soon as possible should it be necessary for you to reschedule or cancel your appointment.

When preparing for an initial consultation, it is very important to obtain copies of all pertinent information including labwork, radiography and previous treatments from your referring veterinarian. In many cases, this information will enable our doctors to complete a diagnostic evaluation without necessitating duplicate testing.

If special diagnostics or surgery are a possible consideration, food should be withheld from your pet after midnight the evening prior to your appointment day.


While our fees for services are usual and customary, an estimate will be provided to you prior to the admission of your pet for diagnostics and/or surgery. A deposit is required at the time of admission to our facility.


The majority of cases seen at Southern California Surgical Group are referred by a general practitioner. Optimal patient care requires mutual communication between the client, specialist and referring veterinarian regarding the patient’s medical history, previous schedules of treatment and specific medications used is beneficial to our overall case management.

Upon completion of the consultation or recovery from surgery, your referring veterinarian will be contacted by telephone and/or with a complete written report regarding the management of your pet. Your veterinarian will administer your pet’s primary health care for many years to come and, thus, it is important for you to maintain an ongoing association with him/her. Referring a difficult case displays a true concern for the well being of your pet.


Southern California Surgical Group has a member of its surgical staff on call at all times to perform emergency surgical and/or diagnostic procedures, or to assist you with answering any questions that may arise regarding the care of the pet. We understand that when an emergency arises, this ability to contact a member of our surgical team is of the utmost importance to the health and welfare of your pet.

Our facility is staffed on a 24-hour basis thereby eliminating the need to have your critically ill or injured animal transported to an emergency facility for overnight monitoring.

All emergency cases will be seen on a priority basis.

Southern California Veterinary Surgical Group is conveniently located in Orange County near the John Wayne Airport and the intersections of the 405, 55, and 5 freeways. Our location enables us to provide immediate access to laboratory facilities and the canine blood bank. In any surgical or diagnostic situation, with time being of the essence, this closeness in proximity to both of these facilities enables us to both identify any potential problems and to expedite treatment.
