Meet the Veterinarians

Dr. Chase Marr, D.V.M 

Dr. Chase Marr was born and raised in rural southeast Kansas. He attended Kansas State University and received a B.S. in animal science in 2010. Always being one with a sense of adventure, Dr. Marr set out on an experience of a lifetime and attended veterinary school at Ross University on the Caribbean island of St. Kitts. After nearly three years of island living, he made the trek back to the States and completed his clinical year of veterinary school at Purdue University in West Lafayette, Indiana. As soon as school was completed, Dr. Marr moved to Denver, Colorado, where he met his husband Richard. Dr. Marr worked as an associate veterinarian in a bustling practice near downtown Denver. There, he was able to grow both personally and professionally.

In his free time, Dr. Marr enjoys skiing, exploring the area, and checking out the local flea markets and antique shops (his collection includes vintage medical items)!

Dr. Marr is excited about being a practice owner and cannot wait to build relationships with pets and their owners.

Dr. Jeffrey Krysinski, D.V.M.

Dr. Jeffrey Krysinski's interest in veterinary medicine has been apparent from a very young age. Having grown up in Grosse Pointe, Michigan, he began working part time as an animal attendant at Harvey Memorial Animal Hospital, where he cleaned the clinic and cared for boarding patients. From there he went on to pursue his passion for veterinary medicine at Michigan State University, obtaining his veterinary degree in 1984.  There he met his wife, Dr. Jane Alexander, and in 1996, they went back to Harvey Memorial Animal Hospital to purchase the clinic and raise a family.  Yearning for greener pastures, they sold Harvey Animal Hospital in 2012. In 2013, they moved up to the Traverse City area and in 2014. Always a proud general practitioner, he was mentored early on towards ortopedic casses and enjoys the challenge of diagnosing and treatment. He is well versed in cruciate ligament, patellar, and simple fracture surgeries. 

Dr. Krysinski is a father of two grown and successfully launched children. He leads an active outdoor lifestyle including alpine and nordic skiing, running, mountain and road biking, and sailing. He is a staunch dog enthusiast, and come autumn you will find him in the woods and fields with his beloved bird dogs. 


Dr. Jane Alexander, V.M.D. 

Dr. Alexander grew up in Gladwyne, Pennsylvania. She graduated from the University of Pennsylvania in 1982 with her doctorate in Veterinary medicine.  Following veterinary school, she completed a one year internship in small animal medicine and surgery at Michigan State University, where she met Dr. Krysinski during her last week.  They married in 1984 and practiced in several different veterinary hospitals until they decided to buy Harvey Memorial Animal Hospital in Detroit in 1996.  For 16 years, they nurtured Harvey’s, which quickly became part of the family as they formed long lasting relationships with the variety of clients and patients they cared for.  But as avid outdoor enthusiasts, Dr. A and Dr. K knew that their hearts were not in the city, and so in 2012, they sold Harvey Animal Hospital, and in 2013, moved to Suttons Bay, Mi.  Though initially planning to work as associate veterinarians for other practices, they soon found that they missed the ownership aspect that Harvey’s allowed.  Therefore, in August of 2014, they took over the ownership of Grand Traverse Veterinary Hospital and then later sold the practice in 2021 but continue to practice part time at the clinic

Soft tissue surgery is one of Dr. Alexander’s professional interests. In 1998 she received a Certificate of Proficieny at the Small Animal Soft Tissue Immersion Program at WAVE in Dallas, Texas. She also finds enjoyment in performing ultrasounds, but more importantly, she is proud to be part of such a professional compassionate team here at Grand Traverse Veterinary Hospital.  Dr. Alexander is always pursuing new athletic challenges.  In her spare time, she can be found training for half marathons, mountain biking, kayaking, practicing yoga, snowboarding and especially dressage training her 3 year old ex-racehorse “Hendrix”.  Most of all, she enjoys spending time with her family, consisting of her husband, Dr. K, and when she can travel, her son Peter (an IT Specialist), her daughter Erin (a small animal veterinarian), and her soon to be son in law Seth (who works in the governors office in SLC, Utah). Also in the family are three dogs; Tag, Ginny, and Tulip. 

Dr. Marianne Jossens, D.V.M.

With a strong desire to love and care for animals, Dr. Jossens found herself drawn to veterinary medicine. After graduating from Michigan State University with her veterinary license in 1981, she moved to Grand Rapids where she spent 10 years as a veterinarian at the Animal Clinic of Grand Rapids, and 6 of those years working for the John Ball Zoo.  During that time, she found that not only did she have a passion for working with small animals, and especially for surgery, but also a deep interest in exotics. In 1990, she and her family moved to the beautiful Traverse City area, where she spent several years expanding her veterinary experience at several clinics before finding her home here at the Grand Traverse Veterinary Hospital.  As a skilled surgeon, Dr. J. enjoys many aspects of veterinary medicine, especially working to improve the quality of life of her patients and getting to know the wonderful people that she meets every day.  Dr. Jossens is well known in the clinic for seeing every patient and client as part of her family, and is incredibly devoted as a result. 

Family has always been important to Dr. Jossens. She has three wonderful children, two sons and a daughter, who have been her primary focus for many years. On her off time, Dr. Jossens enjoys sea kayaking, and has even circumnavigated Lake Superior. Yes, even in the winter months she is out kayaking.  Dr. Jossens is an avid outdoor enthusiast, a wilderness first responder, and an American Canoe Association Kayak Instructor, all of which make her favorite places deep in the wilderness the most comfortable.  She also enjoys playing the violin and practicing martial arts.
