About Us


Dr. David Cowan was the original founder who established Whipple Avenue Pet Hospital in 1979.  After a long and successful career, Dr. Cowan retired and sold the hospital to his Associate Veterinarian, Dr. Cyndi Stiglich in 2015. In late 2021, Dr. Stiglich sold the practice to enjoy semi-retirement.    

Our hospital is located in beautiful Redwood City.  At Whipple Avenue Pet Hospital, we strive to provide the best pet parent experience and medical care for your pet. We are a full-service veterinary hospital primarily caring for cats and dogs.  We are grateful to our local community for their decades of support and look forward to meeting you and your pet!

Pet Insurance

We hope that your pet lives a happy and healthy life but there could be a time where your pet may have a medical event that could be costly. Because of this, it’s good to plan for the unexpected! We encourage pet parents to explore insurance coverage for their pet. We accept all pet health insurance plans. Most pet insurance plans are designed to reimburse you after payment has been made to the veterinary hospital. For more information on pet insurance, please visit:
