Dr. Shannon Heidorn, originally from Riverside, CA, attended the University of California, Davis, where she studied Animal Science. Dr. Heidorn went on to attend veterinary school at Western Univeristy of Health Sciences, graduating with her DVM in 2012.

Following graduation, Dr. Heidorn completed a small animal rotating internship at one of our close sister hospitals, VCA Sacramento Veterinary Referral Center. She completed a second internship in surgery at VCA Animal Specialty and Emergency Center in Los Angeles, CA, and a third in orthopedic surgery and sports medicine at the Veterinary Orthopedic and Sports Medicine Center in Annapolis Junction, MD.

Most recently, Dr. Heidorn underwent a three-year surgical residency at VCA Animal Specialty and Emergency Center in Los Angeles, CA before joining our team. She became a board-certified veterinary surgeon in 2019. Her special interests include orthopedics, regenerative medicine, and soft tissue reconstructive surgery.

When not at work, Dr. Heidorn enjoys swimming, hiking, and snowboarding. She and her husband are excited to attend Giants and River Cats games! They have a cat named Gimli, named after the Lord of the Rings dwarf because he has the same shining personality.

VCA Loomis Basin Veterinary Clinic is excited to offer your pet the most advanced surgical techniques and technology. Though all veterinarians are educated in general surgery and many are proficient at advanced techniques, some surgeries require the services of a board-certified surgeon. Because of that, we have board-certified surgeons who work with us on staff. These board-certified veterinary surgeons are able to perform many different types of procedures your pet might need, including:

  • Complicated soft-tissue procedures for heart, lung, liver, kidney, and other organs
  • Neurological surgery for spinal cord, nerve, or muscle problems
  • Orthopedics to repair joints and bones
  • Oncologic surgeries to remove large or invasive tumors

Surgical specialists follow the same high principles that your primary veterinarian does and understand the importance of communicating with you and the veterinarian who referred your pet for surgery.

Dedicated Surgical Facilities

Our surgical suites are fully equipped with the latest technology. We provide:

  • Fully trained veterinary and technical staff, to ensure the safest, most efficient procedures for your pet
  • Heated surgery tables for greater comfort
  • Advanced sterilization techniques
  • Comprehensive patient monitoring during anesthesia, including temperature, ECG, blood pressure, heart rate, respiratory rate, and blood oxygen saturation
  • Intensive recovery and post-operative care

Loomis Basin uses comprehensive anesthetic monitoring. Your pet's vital signs, such as pulse, respiration, and blood oxygen level, are checked regularly by our dedicated surgical nursing team. We also use the latest in pain relief and pain management techniques. Your pet will be given medicine before, during, and after any procedure to make sure his or her recovery will be much more comfortable.

Why does my pet need a veterinary surgeon?

Just as your own primary care physician may feel the need to refer you to the care of a specialist from time to time, your general practitioner veterinarian may feel your pet needs the additional expertise of a board certified surgeon for certain surgeries. In fact, many general practitioner veterinarians refer all but the most routine of surgeries to specialists'"orthopedic and neurology cases, reconstructive surgeries, tumor removals, etc.

Board certified veterinary surgeons also are often affiliated with referral hospitals where they may have access to specialized diagnostic or surgical equipment, the latest and safest anesthesia monitoring equipment, physical therapy or rehabilitation capabilities, and other critical care services that a general practitioner may not have access to. All of these specialized services may be necessary for the optimal care and recovery of your pet.

You can be assured that a veterinarian who knows when to refer you and your pet to a veterinary surgeon is one that is caring and committed to ensuring that your pet receives the highest standard of care for his or her problem.

What kinds of problems require the expertise of a veterinary surgeon?

Board certified veterinary surgeons can repair complex fractures, perform total hip replacements, and use advanced techniques to repair torn ligaments (ruptured cruciate ligaments) within the knee. They can also remove cancerous growths, manage extensive or non-healing wounds, and perform reconstructive surgery, such as grafting skin over large injuries. Veterinary surgeons can perform intricate surgeries in the chest or abdomen, such as kidney transplants in cats or repairing heart defects in dogs. Spinal injuries and herniated discs are problems that are also commonly referred to board certified surgeons. Veterinary surgery is also expanding into minimally invasive surgery, such as arthroscopy, thorascopy, and laparoscopy.
