She and her husband, Brian, moved to Oregon to pursue their shared interests in the great outdoors.

Since then, she has focused her talents on caring for animals of all kinds.

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.

Dr. Nicholas Szivetgari

DVM, DACVIM (Oncology)
Dr. Szigetvari (aka Dr. Nick) is a University of Illinois graduate who began his veterinary profession as a general practice veterinarian in Chicago, Illinois. After several years of this invaluable experience setting the tone for his approach to veterinary medicine, he decided to pursue a career focused entirely on medical oncology.

This advanced training began with a general internship at University of Wisconsin followed by medical oncology residency at Purdue University. Although he has a strong interest in research and novel therapies, he chose to return to private practice over academic veterinary medicine to better fulfill his desire of connecting with pets and their owners.

After completing years of advance training, Dr. Szigetvari established a full-time medical oncology service for the pets of the Seattle, Washington at Seattle Veterinary Specialists (currently BluePearl Downtown Seattle) from 2016 to 2018. He then relocated to Nashville, Tennessee working at BluePearl Franklin, TN providing oncology services for the central Tennessee, northern Alabama, southern Kentucky pet owners and referring veterinarian population for 4+ years. A longing for the beauty and sensibilities of the Pacific Northwest he returned to Seattle in June 2023.

He finds particular satisfaction in connecting with pets and owners during the challenging time of cancer diagnosis. It is his goal to help make clearer the complexity of the condition and form an individualized treatment plan for pets that meet owner’s needs while also preserving quality of life for pets.

While away from work Dr. Szigetvari enjoys live music, playing guitar, wood working, landscaping, trying new culinary creations, camping through our national parks and forests with his dogs Mabel, Lucille, and his girlfriend, and making sense of their indignant cat named Squish.

Support Team

Heather, CVT, CVPM, FFCP

Heather R.
Practice Manager

Heather was originally attracted to veterinary medicine while she was in high school. The defining moment was when it was time to say goodbye to her longtime companion of her whole childhood, a 16-year-old German Shepherd. The doctor who helped her family at this critical and emotional time shaped her view of the profession and she was set on a path. She first began her career as a volunteer at a local small animal veterinary hospital in 1995. Soon she was invited to become a regular employee. She’s never looked back. Throughout her life, she has worked in all support team member roles (kennel assistant, reception, VA, CVT, and ultimately Practice Manager holding a CVPM certificate.) Her work experience includes small animal private practice, corporate medicine, lab animal husbandry, shelter medicine, industry, and now specialty medicine.

Heather is a Fear Free certified Professional and attributes her love of shy animals to her interest in this area of medicine.

At home, she shares her life with her husband, a mini rex rabbit, a spunky Chihuahua mix, and two feline friends.

Outside of work Heather enjoys reading in her hammock, painting, cheesy horror movies, collecting Christmas ornaments, and taking trips to the coast or the mountains.
