My cat is 15 years old and has been taking medication for hyperthyroidism for a year. I'm from Taiwan and don't speak English, so we had to communicate using a translation app on my phone. Initially, I was very worried and confused about the procedures, but the medical team was incredibly professional. They provided me with a lot of information during the initial email communication, and communication was very quick. Dr. Boshoven was very kind and humorous, which made me feel at ease. All the medical staff were always smiling and showed no impatience even though I didn't speak English. The I-131 treatment was very successful, and the subsequent 30-day and 90-day T4 level monitoring was also very stable and good. Our treatment at this hospital has now concluded, and I am extremely grateful. You not only saved my cat but also saved me. Thank you, Dr. Boshoven, and all the medical staff who cared for MiDo. You were all so warm and kind. You gave MiDo a new lease on life, allowing her more time and a healthier body to be with me. In a country where I don't speak the language, I am truly grateful to have met such warm-hearted people. I wish the entire medical team all the best.

I can’t express how grateful I am to the team at Arizona Veterinary Oncology in Gilbert. From the moment I walked in with my boy Hendrix, I felt embraced by a community of caring individuals. The front desk staff was always welcoming, greeting us with genuine smiles that made each visit a little brighter. The vet techs and oncologists are truly extraordinary. Over the three weeks of Hendrix's treatment, visiting five times each week, they showed incredible professionalism while also treating us like family. They took the time to explain everything, answer all my questions, and just be there when I needed support. What really touched me was their unwavering positivity. No matter how tough things got, their uplifting spirits never wavered. They made such a difference in what was a challenging time for us. I felt like they genuinely cared about Hendrix, and that made all the difference. Thank you, Arizona Veterinary Oncology, for being such wonderful humans. Your kindness and dedication mean the world to me and to Hendrix.

Dr. Lynda Beaver is the best. Koa, my whippet, had a very rare form of Cutaneous Plasmacytoma with small tumors throughout his haircoat. he was on Melphalan and Prednisone from 9/25 to the present with Dr, Beaver and I trying varying dosages with no real progressive changes in the treatment... our attempts had no positive results. with his appointment on 4/3/26 we were to attempt an alternate chemo agent and surgery on an internal rectal mass (suspect plasmocytic mass) that was hemorrhaging and causing much difficulty. my attempts to find a clinic in the phoenix and Tucson area who would do Koa's rectal mass removal in anything less than two weeks was unsuccessful. Dr. Beaver was able to make an appointment with your Scottsdale Surgical Clinic for Wednesday 4/8 with Dr. Tanner Roberts. unfortunately the night of 4/4 Koa's prognosis deteriorated severely where I took him to your Emergency for euthanasia. Dr. Lynda Beaver showed unfailing compassion and interest in Koa throughout this lengthy endeavor. your entire staff at Oncology was equally first class.

Hoss is doing wonderful with his Melanoma vaccines, given every 6 months.. He has been seeing AZ Veterinary Oncology since he was diagnosed. The Dr's and staff are amazing. They are professional and kind to us and our boy. Hoss is always a good boy while he is being treated and has never experienced any trauma while in the hands of the Dr's and staff. I highly recommend this specialty vet office if your pet is needing such treatment.

Arizona Veterinary Oncology and Dr. Eric Boshoven quite literally gave my senior dog, Potato, her life back after other veterinarians were already steering us toward euthanasia. Potato is a 14–15-year-old multipoo mix with a urethral tumor extending into her bladder, and everywhere else her diagnosis felt like the end of the road, but this team offered us a real treatment plan and hope. Dr. Boshoven recommended stereotactic radiation tailored specifically to Potato, and he and his staff explained every step of the process in clear, compassionate terms so I always understood what was happening and why. The entire team treated Potato gently and respectfully at every visit, and they treated me like a partner in her care, answering all of my questions and taking my concerns seriously. Since completing treatment on February 9, 2026, Potato’s quality of life has improved dramatically. Her energy is fantastic, she runs around and acts like a happy older dog, her appetite is big, and her urination is noticeably better than before treatment. For a dog we once thought we were going to lose, the extra good-quality time we now have together is absolutely priceless. I am incredibly grateful to Arizona Veterinary Oncology and Dr. Eric Boshoven for giving Potato another chance and for focusing on her comfort and happiness, not just her cancer. I would highly recommend this team to anyone facing a pet cancer diagnosis, especially if you’ve been told euthanasia is your only option Thank you for Everything !!!!
