Get to know our doctors!

Dr. Daniel Gray, DVM

Dr. Gray is originally from Cedar Falls, Iowa, and graduated in 2004 from the Iowa State University of College Veterinary Medicine. During his education, he dedicated a large amount of his free time to education in wildlife and exotic animal medicine. From 2004-2006 he practiced in a small animal practice in Dubuque, Iowa, before coming to Green Bay to work with Gentle Vet Animal Hospital. From 2005-2013 he was also a disaster response veterinarian working for the National Veterinary Response Team 5 through the U.S. Department of HHS and the Veterinary Medical Assistance Teams through the AVMA. He retired from these organizations in late 2012 to become a partner at Gentle Vet Animal Hospital, and as of July 2019, is now the full owner.

He currently resides near Luxemburg with his wife and 2 boys, along with a house cat, a Golden Retriever, a cockatiel, a betta fish, a bevy of barn cats, and more chickens than he will admit to!

Dr.Amelia Gessner

Dr. Amelia Gessner-Knepel, DVM

Dr. Gessner is originally from the Metro Detroit area and attended both undergraduate and veterinary school at Michigan State University, spending her elective classes learning exotic pet and zoo medicine. Next, she moved out to College Station, TX, for a small animal internship at the Texas A&M Veterinary Teaching Hospital, and then to South Florida, where she practiced primarily exotic pet medicine. She and her husband then decided to make Wisconsin their home base and moved to Northeastern Wisconsin in 2016. You may have seen her after hours or on the weekends at the Fox Valley and Green Bay Animal Referral Centers before joining the Gentle Vet Animal Hospital team.

Dr. Gessner loves all species but has a special interest in exotic pets, and zoo, and wildlife species. She enjoys working with the Bay Beach Wildlife Sanctuary and the NEW Zoo.

She currently lives in Appleton with her husband and their fur-babies, a cat named Zander, and Blue Bell, a pit bull mix. She enjoys team sports, fitness, baking, and ballroom dancing in her spare time.

Dr. Karis Quandt-Walle, DVM

An area local, Dr. Karis Quandt-Walle grew up in Appleton before attending the University of Wisconsin, Madison for her undergraduate degree. During that time, she worked as a surgical technician at the vet school. She then attended the University of Illinois College of Veterinary Medicine, graduating in 2021. While in school, she spent her elective classes on exotic animal, zoo, shelter medicine, and surgical-focused courses. In addition, Dr. QW was heavily involved in the wildlife medical clinic, working especially with birds of prey. This sparked her interest in exotic and avian medicine, and after graduating, she was eager to return to her homeland with her new skills. She is excited to help out with pet care, as well as wildlife cases, at Gentle Vet.

When not practicing medicine, Dr. QW can be found running, bird watching, playing rugby, attending rock shows, and exploring the great outdoors. She currently lives in Appleton with her cat, Bo.

She recently completed a specialty internship in avian and exotic medicine and surgery in Houston, Texas, at Gulf Coast Veterinary Specialists. Dr. Lacy and her fiancé have two dogs (Finley and Bella) and a cat (Joey).

Jessica, Assistant

My name is Jessica Ward, and I am a veterinary assistant. I started here at Gentle Vet Animal Hospital in the summer of 2011.

I enjoy getting to build relationships with pets and their families as we continue to see them through their lives. Getting to see a pet through different life stages and watch their bond with their family grow is so rewarding. I also have a special love for crabby cats and reptiles of all kinds!

I’ve been keeping reptiles since 2007 and always love to learn new things about them. I especially enjoy creating naturalistic habitats for them and seeing their natural behaviors. Using my experiences to help serve our clients and patients better is very important to me.

In my free time, I enjoy caring for my family (husband, small herd of cats, various herps, ducks, and chickens), cooking, and pretending to have a green thumb.

We’re Silver certified!

So what does that mean for you and your pet?
From the Low Stress Handling information page:

“This logo signifies that the people you are dealing with have spent a lot of time learning Dr. Yin’s methods for reducing stress in animals. They know how to hold a leash, how to offer treats and counter condition animals to having medical treatment, and the perfect way to do a medical wrap. What does that mean to you? Simple: a more pleasant experience at the vet’s and a happier pet. It also means that they can use methods that can reduce the need for sedation first, reducing risk and pet health costs. It means you can trust that person to treat your pet like you’d want them to be treated. With skill, professionalism and care. Whether you see this on a certificate or a nametag, it says good things about how your pet will be treated and that gives you peace of mind.”

To become Silver Certified, our team has spent 15 hours on lectures, 12 hours on practice sessions, and have taken 10 tests plus a final exam, passing them all with flying colors. When you visit us, you can rest assured that your pet is handled with respect and gentle restraint. We are committed to providing YOUR pet with the most stress-free veterinary experience possible!
