What is a Veterinary Oncologist?

A veterinary oncologist is a veterinarian with a minimum of 2 years of specialty training beyond veterinary school.  Most veterinary oncologists have completed a 1 year small animal internship followed by a 2 or 3 year residency training program in medical oncology.  In addition to residency training, certification as a Diplomate in the American College of Veterinary Internal Medicine, subspecialty of Oncology, requires satisfactory completion of a 2-part examination and publication of a research project in a peer-reviewed scientific journal.

She then completed an internship in small animal medicine and surgery at the University of Pennsylvania in 1997 and a 3 year residency in medical oncology at the University of Wisconsin-Madison in 2000.

She became a diplomate of the American College of Veterinary Internal Medicine, subspecialty of Oncology in 2001. Dr. Hershey worked for Arizona Veterinary Specialists in Gilbert , AZ for 3 years before opening Integrative Veterinary Oncology in Phoenix, AZ in 2005. IVO moved into their state-of-the-art hospital in October 2013.

Dr. Hershey has won numerous awards for her research on inhalation chemotherapy and vaccine sarcomas in cats and has been included in the Manchester Who’s Who Among Executives and Professionals for her professional accolades and achievements. She has authored and co-authored multiple publications, including several book chapters. Dr. Hershey is a member of the Veterinary Cancer Society, the American Veterinary Medical Association, the Arizona Veterinary Medical Association, the American Association of Traditional Chinese Veterinary Medicine, the American Academy of Veterinary Acupuncture and the American Holistic Veterinary Medical Association.

Office Manager
Prior to working with Dr. Hershey, Lori was the Site Administrative Assistant at a weathering laboratory for 16 years, where she was responsible for billing, payroll, benefits and the front desk. She worked most recently as a Customer Service Specialist at a golf club animal headcover manufacturer.

Lori has always had a passion for animals, since she was a little girl growing up with 2 Saint Bernards, and has always been known as the “crazy dog lady” at previous jobs. She is grateful for the opportunity to work with Dr Hershey and all of the IVO staff and learn more about the veterinary field, specifically veterinary oncology. Lori lives with her husband Gabe and together they have 7 Golden Retrievers, a cat and a box turtle. Together they enjoy traveling to dog shows and showing their Goldens in Conformation and Obedience.


Lisa has always had a passion for animals, growing up in a family that bred, rescued, and showed dogs. She’s owned pets ranging from dogs, cats and ferrets to frogs, turtles, and lizards.

After finishing school in San Diego, Lisa moved back to Phoenix where she was born and raised. She has worked in the veterinary field since 2013 as both a Vet Assistant and Receptionist.

Lisa has three rescue dogs who she considers her “children”. Some of her favorite activities are attending baseball and hockey games, going to country music concerts, doing crafts/DIY projects, and spending time with her friends and family.


Certified Veterinary Technician
She grew up in San Diego where she worked for a veterinarian after school. Ultimately moving to Phoenix in 1988, Terry has been in the veterinary field for 30 years and has been with Dr. Hershey since 2010.

She and her husband have a beautiful daughter, 3 dogs, 3 cats, an Umbrella cockatoo, several box turtles, desert tortoises, hermit crabs and fish. Terry loves camping, boating, the sand dunes and the NHRA drag races.

Terry and her family also enjoy fostering pets in need. Terry has great pride and compassion in caring for IVO clients and their pets. She is especially fond of geriatric pets and enjoys being a patient advocate.

Veterinary Technician
Was born in Los Angeles, CA, and moved around until she nestled in Phoenix, AZ. Growing up she knew she wanted to be in the veterinary field, and would always play with her stuffed animals pretending to be a Veterinarian.

She started working in a kennel facility at a general practice in 2007, and since then has experience in Neurology and Emergency, and now Oncology. Her favorite thing about being a technician is knowing she is there nursing and making animals feel comfortable during their difficult time.

Melissa has a beautiful daughter, Emilee, and loves spending as much time as possible with her. She enjoys mini vacations to the beach, and, being a kid at heart, loves trips to Disneyland. Music plays a big part in her life, and she listens to everything from Golden Oldies to Classic Rock.


Veterinary Technician
Has been in the veterinary field 4 years. Born and raised in Arizona she always had an understanding and love for animals, especially dogs. She started off as a kennel assistant and is now a technician. She has even worked with exotics such as pocket pets, birds, and even monkeys!

She has 3 dogs, 1 cat and 2 desert tortoises. Becca is very family orientated, being the youngest of 3 sisters and an aunt to a 2 year old, and a brand new nephew! She enjoys doing photography and listening to music. Her music variety comes from her father, ranging from The Rolling Stones to Elton John.

Becca is really excited to learn more about oncology and the different types of treatment that can help our patients every day!
