Kim Freeman

DVM, DACVIM (Oncology)

Dr. Freeman has been practicing oncology in the Portland area since 2003. Originally from Clarksville, TN, she graduated from the University of Pennsylvania with a Bachelors of Arts in History. She achieved her DVM from the University of Tennessee, Knoxville and did a one year rotating small animal medicine and surgery internship at the Atlantic Veterinary College in Prince Edward Island, Canada. Dr. Freeman completed her medical oncology residency at Gulf Coast Veterinary Specialists in Houston, TX and became ACVIM board-certified in oncology in 2003. She founded the Veterinary Cancer Referral Center in 2009 and merged this practice with Veterinary Surgery & Orthopedics to form Veterinary Cancer & Surgery Specialists in 2014.

Dr. Freeman’s primary focus is on integrating the latest in cancer therapy with quality of life care. Kim takes great pride in educating her staff to provide excellent care to our patients. She and her husband, Brian, moved to Oregon to pursue their shared interests in the great outdoors. They spend much of their free time backpacking or skiing in the mountains, surfing at the coast, and cooking amazing meals to share with friends. Kim and Brian share their home with Raven (the most snuggly athletic dog ever) and Rafa (the charming and handsome tuxedo cat).

John Wooldridge

DVM, Diplomate ACVS

Dr. Wooldridge attended veterinary school at Atlantic Veterinary College of the University of Prince Edward Island before completing an internship in small animal medicine and surgery at The Animal Medical Center in New York City and then a residency in small animal surgery at the University of California, Davis. He became board certified as a specialist in small animal surgery by the American College of Veterinary Surgeons in 2001. Dr. Wooldridge co-founded Veterinary Cancer & Surgery Specialists in 2014 and has been in specialty practice in the Portland area since 1999.

His professional interests span both soft tissue and orthopedic surgery, including oncologic (cancer) surgery, hepatobiliary and urinary system surgery, fracture repair, cranial cruciate ligament disease, patellar luxation, and the relationship of limb alignment to common orthopedic problems.

Jim Perry

DVM, PHD, DACVIM (ONCOLOGY), DACVS-SA

Dr. Perry received his Bachelor’s degree at the University of Washington, then went on to complete his DVM, Ph.D., and medical oncology residency at Colorado State University. He practiced medical oncology and completed a surgical residency at Aspen Meadow Veterinary Specialists in Colorado before moving to the Northwest to practice surgery and oncology at Seattle Veterinary Specialists. He spent four years practicing in Seattle, followed most recently by two years working as an Assistant Professor of surgical oncology at the University of Pennsylvania and exploring the East Coast. The latter was particularly exciting to build research collaborations and to teach future veterinarians, interns, and residents.

Professionally, Dr. Perry finds all aspects of surgery and oncology rewarding, particularly the strong bond that he is able to form between patients and their owners alike. While his focus of practice will be in all aspects of orthopedic, soft tissue, and oncologic surgery, he brings extensive experience and expertise as a board-certified specialist in both medical oncology and small animal surgery. In his spare time, he loves being outdoors with his family, whether it is the coast, the Cascades, or just enjoying his friendly hometown.

Dr. Susie Kang

DVM

Susie Kang is an enthusiastic and devoted animal lover. Susie began training to be a veterinarian in the sixth grade when her family welcomed a puppy into their home. Since then, she has focused her talents on caring for animals of all kinds. Her formal education began at the University of California, Davis, where she earned degrees in Animal Science (B.S.) and Veterinary Medicine (D.V.M.). Dr. Kang continued her studies by completing a rotating small animal internship at Purdue University. She then completed a medical oncology residency at Cornell University. She is a board-certified medical oncologist and has been in private practice for over six years.

Dr. Kang strives to achieve the best possible outcomes for her furry patients, along with their human companions, every day. She has a special interest in treating mast cell tumors, lymphomas, osteosarcoma, hemangiosarcoma, and palliative care.

While not at work, Dr. Kang enjoys reading, cooking, and the great outdoors. She is certainly a cat person, having once attended a traveling cat show, art exhibits featuring life (and adoptable) cats, and has visited a cat cafe. Her gray tabby Dimitri can give “high fives” and perform other unique tricks. Her dog, Merlin, enjoys jogging and couch surfing.

Dr. Kang looks forward to helping you and your beloved companions during the difficult time of a cancer diagnosis.

Katherine Hall

Katherine Hall
Oncology Technician

Katherine studied Social Work at Washington State University, and like many college students, she got a dog. Her name was Baggy, and she changed Katherine’s life. Baggy had major orthopedic surgery as a young dog (to correct a genetic problem), and Katherine spent a fair amount of time at the veterinary clinic with her. Her interest in veterinary medicine was sparked. Katherine has worked in veterinary medicine for 11+ years, primarily in emergency and critical care, prior to transitioning to oncology a few years ago.

Katherine has always felt a close connection to animals. Being able to help them during illness and recovery feels natural.

Finnegan is around 2 years old. He is a Doberman mix that closely resembles the dogs on the Far Side comic in both appearance and attitude. Chooch is an elderly Chihuahua who thinks he is a cat. Katherine also has an actual cat named Schnitzel, who is certain that she is Ruler Of All.

Tammy Perez

Tammy Perez
Oncology Technician

Tammy grew up in Eastern Washington in the Columbia River Gorge. She has lived in Seattle, Arizona, Los Angeles, but decided Portland was the best place to raise her daughter.

She gained additional experience at an emergency clinic in Los Angeles, a specialty clinic in Portland, and spent over four years working with a local radiation oncologist. Because Tammy is a self-described cinephile, who also loves reading, all of her pets have amazing names! She has a tiny six-pound chihuahua named Hedy Lamarr that rules the household. Tammy enjoys collecting and selling vintage items and playing board/card games with family and friends.
