Stuart Helfand, DVM
Dipl. ACVIM (Oncology and SAIM)

Dr. Helfand is a graduate of Colorado State University and comes to Cedar Mill Veterinary Hospital after more than 30 years in academic veterinary oncology. Following completion of his oncology residency at the University of California Davis, Dr. Helfand held faculty appointments at the University of Pennsylvania, University of Wisconsin, and Oregon State University.  He was actively engaged in clinical and research aspects of veterinary oncology.  Dr. Helfand is a seasoned clinical oncologist, with an eye towards bringing innovative and more effective cancer therapies to clinical practice.   

He strives to deliver compassionate care that helps to keep his patients happy and free of pain, with a good quality of life. There are almost always options and we promote setting goals together so you are able to make informed decisions for your pets that feel comfortable and safe.  Dr. Helfand greatly values input from pet owners and graciously accepts the privilege entrusted to him in providing cancer care for beloved pets.

Dr. Helfand enjoys skiing with his daughter (when he can catch her), cycling, gardening, good food, live music, and occasional caretaker for an energetic springer spaniel and part-time house mate named Maple.

His special interests include tumor immunology and cancer immunotherapy, personalized cancer therapy, and targeted cancer therapies, staying abreast of contemporary ideas and discoveries in the cancer field that may help improve outcomes of pets with cancer.
