Meet the Team


Dr. Hahn is co-founder of Stonetree Veterinary Clinic. She grew up caring for sheep, rabbits, chickens dogs and cats on a small family farm in eastern Washington. She worked her way through college, obtaining a Bachelors degree in Bible and Theology. Next, she embarked on a path to become a Doctor and was accepted into Washington State University’s College of Veterinary Medicine. In 2010 she began practicing medicine in Ketchikan, then in 2013 partnered with Lorraine to open Stonetree Veterinary Clinic.

In order to meet the needs of our community, Dr. Hahn performs a wide range of procedures, from basic exams to management of complex medical conditions. She is a certified Fear Free professional and has donated time performing surgeries in both South America as well as right here in Alaska. While Dr. Hahn enjoys the wide variety of patients and personalities that come through our doors, she has a particular interest in soft tissue surgery, feline medicine and working dogs.

Dr. Hahn’s immediate family consists of her husband Tony, and stepchildren Toni, Jessica, Joshua plus two dogs: Birch a geriatric Great Pyrenees and Jaeger who is a working line Dutch Shepherd. Jaeger is training to compete in Schutzhund. Along with the dog training, Dr. Hahn and her husband enjoy traveling, hunting and other outdoor activities, along with simply enjoying the rare opportunity to simply relax at home.


Lorraine is co-founder of Stonetree Veterinary Clinic. She and her husband, David, moved to Southeast Alaska in 1987. They raised their family in Southeast Alaska living in Juneau, Wrangell, and landing in Ketchikan in 2003. They have three children who all graduated from Ketchikan High School. Their oldest, Stephanie, has two children and works in Anchorage as a clinical social worker. Emilee has graduated with her doctorate of veterinary medicine and is working in Coeur D'Alene, and Matthew who served in the United States Army and now is working towards a new career.
