Meet Our Team in Zion

Tonya Gray

DVM, Owner

Dr. Tonya Gray received her Doctorate of Veterinary Medicine from the University of Illinois Urbana-Champaign in 1998. Her areas of interest include dentistry, having completed extensive training from the University of Wisconsin Madison, and emergency surgery. She holds professional memberships with the Chicago Veterinary Medical Association (CVMA), the American Veterinary Medical Association (AVMA), and the Illinois State Veterinary Medical Association (ISVMA).

Dr. Gray chose her career path for the love of science and pets. She knew veterinary medicine was the right fit since high school and enjoys nurturing close, longtime bonds with families as they care for pets. Her most rewarding experience in her career is opening Zion’s first animal hospital and offering residents affordable veterinary care that’s also state-of-the-art.

Dr. Gray married her husband Rick the same year she started veterinary school. Raising their three sons, Ricky, Derrick, and Benjamin, is her greatest life accomplishment. When she’s not busy helping pets and their families, she’s cooking for hers, watching her sons play sports, weight training, or running – she recently ran her first half-marathon.

Linda Lewiston

Associate Veterinarian

Dr. Lewiston earned her DVM from Iowa State University in 2009. She then completed a small animal rotating internship at Animal Emergency and Referral Center in Northbrook, IL. She is a graduate of the Karen Pryor Training Academy and is a certified training partner. Prior to becoming a veterinarian, she worked as a high school science teacher, a junior high/high school guidance counselor, and an emergency medical technician for a hospital-based ambulance service. She got into veterinary medicine because she had a cat that started having seizures. The veterinarian that took care of her encouraged Dr. Lewiston to become a veterinarian, and so she did! In her current role, she enjoys working with animals and giving them the best quality of life possible. She believes that in order to work with animals, you must work with the owners, and that can be extremely rewarding!

At home, Dr. Lewiston has two Boxers and four Golden Retrievers. She and a friend breed Golden Retrievers and many of the puppies have become service dogs. One is even a drug sniffing dog with a police department! She enjoys doing conformation, obedience, and agility with her dogs and has earned obedience titles and good citizen titles for many of them! She also works with many rescues to help dogs who have behavioral issues become better suited for adoption. In addition to her dogs, she has multiple cats that are all rescues who needed a place to call home! In her spare time, she enjoys curling up with a good book and cat on her lap.

Cindy Tippet

Practice Manager

Cindy is excited to be at Gray Animal Hospital and she looks forward to working with our team and our patients. What she finds most rewarding about her position is being able to work with so many great people and helping in any way she can—she’s a people person, and she loves helping others. Cindy married her high school sweetheart, Jeff, and they now have three grown children and three grandchildren. She’s extremely proud of them, and could not ask for a better reward in life. Cindy and her husband also have two pets; a Yellow Lab named Phoebe and a male Butterfly Betta named Fin. She loves spending time with her family, along with doing needlework, babysitting her grandkids and watching the Chicago Blackhawks.

In her current role, she loves helping with surgeries and seeing pets improve while in her care.

Maria and her husband, Francisco, have two children, Grecia who is studying for her master’s degree, and Francisco who is finishing his undergraduate degree. They have a dog, Milo, an Australian Shepherd, Pancholin, a cockatiel, and many fish! In her spare time, she enjoys listening to music and reading.

Olivia Janus

Veterinary Technician

Growing up, Olivia always had animals around; mostly dogs, including a German Shepherd, Golden Retriever, and Siberian Husky. She began her career while working at a doggy daycare. From there, she decided that due to her love of animals and medicine, it was only fitting that she attend school in order to complete a veterinary assistant program. She became a Certified Veterinary Technician through Harper College, and has now been in the veterinary field since 2012. For Olivia, the most rewarding thing about being a veterinary technician is taking care of sick pets and helping them recover. She also enjoys helping and educating owners with any pet-related questions or concerns they have.

Olivia and her family share their home with quite a few pets. Their furry family includes 5 cats named Bear, Bruce, Alfred, Billy, and Binx, and 2 dogs named Raef  (Siberian Husky) and Tadashi (Bulldog/Pit Bull mix). Among Olivia’s favorite things to do are spending time with her family, being outside, cooking and baking, painting, and restoring antique furniture.

Monica Cordero

Veterinary Assistant

Monica decided on a career in veterinary medicine due to the passion she has for animals. She believes that her greatest life accomplishment so far has been to professionally work for the care of animals.

At home, Monica lives with her family, Alex, Alex Jr., and Kassandra, as well as their pets, Diesel, a German Shepherd, and Guillermo, a green checkered bird. When she has time, Monica enjoys reading, spending time with her family, and exercising.

Angie Domena

Veterinary Assistant

Every since she was a little girl, Angie has dreamed of having a job where she could help animals. As someone who was always fascinated with the medical aspect of animal care, it seemed fitting for her to seek a career in the veterinary industry! She received her certificate as a veterinary assistant from the College of Lake County to further her career in veterinary medicine. Now, she gets to work with animals every day, and finds that the most rewarding part of her job is helping animals day-in and day-out.

At home, she and her spouse have a son, Nicco, as well as a Chihuahua, Sugar, and a freshwater tank filled with 3 fish and shrimp. In her spare time, Angelica enjoys drawing, going to forest preserves with her dog and son, and cooking—particularly her favorite dish, fettucine alfredo!

Lisa Robinson

Veterinary Assistant

Lisa is currently finishing school at Animal Behavior College to complete her veterinary assistant program. She spent most of her working life in HR before pursuing a career in veterinary medicine. She’s always had animals, and currently shares her home with 3 dogs. Lisa’s dogs each have their own medical issues that she has to attend to, so she’s grateful that she is able to make a difference in their lives and the lives of other animals. It brings her joy to see the relief on a pet owner’s face when they see their “baby” is feeling better. Lisa is also glad to be able to offer comfort to those who are grieving the loss of a beloved pet. Another aspect of her job that she finds rewarding is having a part in relieving an animal’s suffering and seeing them return for a checkup doing 100 times better.

Lisa’s family includes her husband Derrick, their daughter Rosey, and their dogs Benji (mixed breed), Mussy (Australian Shepherd), and Frankie (Chihuahua/Pug). One of Lisa’s biggest accomplishments so far is helping her daughter grow and flourish in her career path, encouraging her to overcome her struggles and build on her strengths. She’s extremely proud of what her daughter has achieved. Outside of work and studying, Lisa enjoys crocheting, cooking, and paper crafting (mainly card making). Her faith is also very important to her.

Lisa is excited to be at Gray Animal Hospital and is so grateful for the opportunity to make a difference. She loves going to work and has a very full heart (and sometimes sore body) when she comes home, but she wouldn’t have it any other way. She looks forward to continuing her studies and becoming a Certified Veterinary Technician.
