Our Team!


Jennifer Cattet Ph.D. CPDT-KA

Co-Founder/Executive Director

Jennifer, along with her husband Jack Topham, founded Medical Mutts with two goals in mind: helping those who need service dogs and helping dogs that have been abandoned find a quality forever home.

Jennifer has a Doctorate in Psychology with a specialization in Animal Behavior (Ethology). She completed her studies at the Faculty of Psychology in Geneva Switzerland where she was an assistant professor for 8 years. She has worked professionally as a dog trainer and behaviorist since 1988.

Jennifer started the first professional dog training school based on clicker training in France (Animalin). She is the author of “Selecting and Training Your Service Dog: How to Succeed in Public Access Work.”

Passionate about helping people in difficulty, she learned how to train service dogs while working as the Director of Training for ICAN, a local prison-based organization. She enjoyed coaching the inmate trainers and helping them develop skills to better their lives while helping people with disabilities. It was during those years that she learned about the impact of life-threatening conditions, such as diabetes and started developing training protocols for medical alert dogs. Her love for dogs led her in 2013 to continue working with service dogs while also making a difference for dogs in need. She since has set her focus on medical conditions and the use of scent for service dogs. 

With her scientific background, she also contributes to ongoing scientific research in the field of medical detection and has co-authored the first peer-reviewed studies proving the existence of a scent, that dogs can be trained to detect, in patients with diabetes or epileptic seizures. Given her expertise in the field of service dog training and medical detection, as well as her fluency in both English and French, Jennifer also coaches service dog organizations and trainers internationally. Her coaching services can be found at https://assistancedog.center/.

Jack Topham

Co-Founder/Director of Finance and Administration

Jack is often the first person you’ll get to talk to when you call the office. He’ll take the time to listen and understand your needs and will go over our different programs so you can make the best decision. If we can’t help you, he’ll try to direct you to the right source and provide you with all the information you need about service dogs in general. He keeps track of new trends in the service dog world and a list of all the other service dog organizations that he can refer people to. Every day of the week, he responds to over 30 inquiries with patience and understanding.

Jack is in charge of finances and administration. He also provides customer support and services. He is a stickler when it comes to processes and keeping the organization on the right path and in good standing.

Jack is also responsible for staff management and supply purchasing. He has been involved in service dog training since 2009 and is always looking for new ways to help both the people and the dogs.

With his office wide open to any person walking through the door, Jack is often sharing his space with the office cat, Marvin. Marvin loves to make messes with Jack’s piles of important documents or jump on his computer at the worst of times.

Sandi Kammerer

Volunteer Coordinator

After witnessing a Medical Mutts service dog graduation ceremony, Sandi realized that there are so many different ways that service dogs can impact the quality of life for their partners and wanted to help.

As Program Manager for Paws and Think, Inc., Sandi learned how beneficial our relationships with our dogs can be. She has years of experience in project management and program development including recruitment, training, and supervision of volunteers. This experience also includes training dog handlers to understand canine behavior and watch for stress signals with a focus on advocating for their dogs.

In March 2017, in order to learn more about the Human-Animal Bond, Sandi took classes with Animal Behavior Institute and became a Certified Animal Assisted Therapy Professional.

She currently volunteers as a therapy dog team for Paws and Think, Inc. with her dog Daisy, at the White River Library with my niece, and at the USO at Camp Atterbury with my sister. She is also a member of the Indiana Crisis Assistance Response Team. In her free time, she loves to read and do flower arranging.

With her husband, Larry, she shares our home in Greenwood with two dogs, Penny and Daisy, and two cats, Cassie and Watson, who all get along… most of the time.




Marvin came from Indianapolis Animal Care and Control. He was adopted over the winter of 2020 and has made a home at our offices at Medical Mutts. Marvin has several important roles in the office. He is the greeter to anyone coming through the door and the cat tester for all of our service dogs in training. He also makes sure to provide the staff with plenty of entertainment.

Marvin believes that he is the official owner of the facility and makes sure the staff caters to all of his needs. He often drives Jack crazy by removing all of the documents from his corkboard or pushing papers out of the printer!
