Dr. Rizzo was born and raised in Philadelphia, PA, but has fallen in love with the Pacific Northwest. She loved animals from a very young age and used to beg her mother for a pet – any pet. When she was 12, her mother gave in and bought her two newts. Sadly, this did not work out well. It wasn’t until she was 17 when her mother agreed to let her take home a grey tabby kitten who she named Simba.
Simba stood by Dr. Rizzo’s side while she finished high school and attended undergraduate school. He especially liked lying on her textbooks while she was taking notes. When Dr. Rizzo’s soon-to-be husband, Jim, convinced her that she needed to go to veterinary school, Simba and their new addition, an orange tabby named Presley, followed them to Southern California where she attended and graduated from Western University of Health Sciences College of Veterinary Medicine.
While she was in veterinary school, Dr. Rizzo became fascinated by cancer. Several members of her human and animal family had suffered from cancer – some survived and some did not. Sadly, one of those family members was Simba who, at the age of 13, passed away due to metastatic pancreatic cancer.
So while she knew of cancer her whole life, she had no idea, until veterinary school, that cancer is an umbrella term for a spectrum of diseases. Although they are all united by the commonality of cellular proliferation, they are also each characterized by unique behaviors, progressions, and responses. She was hooked instantly and, in her first quarter, she decided she was going to be an oncologist.
Four years later, Dr. Rizzo, Jim, Presley, and their two canine additions, Molly and Teddy, traveled to Tinton Falls, New Jersey so that Dr. Rizzo could complete a 1-year rotating internship in veterinary internal medicine and surgery at Garden State Veterinary Specialists. It was there that she developed a deep love and respect for the veterinary support team. Veterinary technicians and assistants work tirelessly and selflessly to care for animals, animal caregivers, AND the veterinarian. For Dr. Rizzo, they taught countless lessons. For example, they taught her how to read an ECG (thank you Kristieeee!), how to stay calm when a patient is actively suffering from seizures and the neurologist hasn’t arrived yet (you rock Meghan!), and they offered a tremendous amount of emotional support on long overnight shifts that threatened to never end (I’m talking to you Shannon!).
Veterinary technicians and assistants are the beating heart of any veterinary clinic and it is impossible to thank them too often for their devotion, technical skill, compassion, and all-around support. The best veterinarians are only that with the support of the whole team and Dr. Rizzo is no exception.
Then it was on to Ithaca, NY where Dr. Rizzo completed a 3-year residency program in medical oncology at Cornell University and where she acquired Digger the beagle.
As you can imagine, it was at Cornell where Dr. Rizzo started to learn about the complexities of cancer. She conducted both bench side and bedside research and eventually used that research to complete three peer-reviewed articles. Maybe equally as important though, she learned the critical nature of teamwork.
Dr. Sullivan was born and raised in Sydney, Australia. She attended The University of Sydney, where she completed her Veterinary degree in 2016. She then moved to the US to be with her (American) husband in upstate New York. In 2020, she moved to the PNW and has worked at local Tacoma hospitals since then.
Dr. Sullivan enjoys exploring the PNW, baking, crafts, and home life with her husband, William, and 5 pets; two dogs, Saint and Prim, and three cats, Tigger, Thor, and Vegemite.
Dr. Sullivan joins our team as a general practitioner to assist in the care of Dr Rizzo’s oncology patients.
Amber did leave the veterinary field in 2019 to obtain her Bachelors of Zoology degree. After graduating she spent some time working with the exotics. In 2022, Amber joined Hope Veterinary Oncology Services as the Hospital Practice manager. Amber is grateful to be working with her team because everyone is dedicated to the care of the patients and the clients. Amber stives to continue a happy work-life balance for her team and the exceptional care that is provided through their services. Amber enjoys days in with her cats, Mr. Link and Nefertiti.
Alyssa chose to work at Hope Veterinary Oncology Services because of the same values that she has surrounding bringing compassion and knowledge to owners to help improve their pet’s quality of life. Before joining the team officially in 2022, she had seen the dedication the team brought to their patients, and she is now thankful to be part of that.
In her free time, Alyssa enjoys camping and exploring the PNW with her dog, Harvey and partner, Jairus. When they are not getting lost in the woods, she can be found in her garden or cuddling her cat, Kitten.
Sarah started off in the veterinary field with the goal to work as Certified Canine Rehabilitation Practitioner which she did for over a decade before “retiring” and moving on to other fields. She became interested in oncology a few years ago after she had a previous pet diagnosed with lymphoma who underwent treatment. She is excited to assist bringing similar services to others’ pets closer to their homes with the help of the Hope Mobile. When she is not helping care for our patients, she can usually be found on the trails, sometimes with her dog, Kaia, and sometimes with her husband, Bob.
