Kristy received a Bachelor of Science degree in Biology from the University of Colorado at Denver in 2004 and was accepted into the veterinary program at Colorado State University in 2005. She received her Doctorate in Veterinary Medicine from CSU in 2009, graduating with honors. Thereafter, Dr. Kreutzer has spent her entire veterinary career practicing small animal medicine in the front range of Colorado.
Dr. Kreutzer and her husband decided to start a small animal practice due to the fact that a large number of private practices in the industry are being converted to corporate entities. Practice ownership allows her to focus on providing customized care to meet the needs of each and every patient and their family.
Dr. Kreutzer’s professional interests include ophthalmology, internal medicine including ultrasound, and end of life care. Her personal hobbies include reading, and travel. Dr. Kreutzer lives in Arvada with her husband Cory and two children, Mason and Hazel. They have three crazy dogs, an old Boston Terrier named Oliver, a sweet Goldendoodle named Darla and a spunky Boston Terrier puppy named Kermit.


During the summers while in college, she was a leader of outdoor education/travel trips for teenagers. These trips brought her to the western part of the country, where she discovered her love for Colorado and the mountains, in particular. Marcy practiced veterinary medicine for six years in Chicago before relocating to beautiful Colorado 18 years ago to enjoy the mountains and outdoor lifestyle.
For the past several years, Marcy has been practicing in Boulder. She is excited to join Dr. Kreutzer, Dr. Sackal and the rest of the team at Sunshine Animal Hospital. Marcy particularly enjoys getting to know her clients and patients well so that she can provide individualized high quality care throughout their lifetime.
Marcy resides in Lafayette with her cats Simon, Lincoln and Linus. In her free time she enjoys rollerblading, snowboarding, skiing and hiking.

She has wanted to be a veterinarian as long as she can remember, but what really solidified her decision was moving to a hobby farm as a small child, and slowly accumulating a menagerie of different animals. She quickly realized her passion for medicine while caring for them, and further solidified this passion with research into human genetic disorders during her undergraduate period, and renal cancer during vet school. As a veterinarian, she loves continuing to learn about new treatments and conditions. Some of her special interests include feline medicine, dermatology (California is full of fleas and allergies!), ophthalmology, and internal medicine.
She resides in Superior with her husband Jesse and their toddler Sophie. They have two dogs- a big goofy husky-lab mix named Maui and a smaller mutt from Taiwan named Miho- and too many cats, Mochi and Myrtle being the ones who love her best. Mochi is a ragdoll who has been to one show, and has since been to nearly every type of veterinary specialist because she's a medical anomaly. Myrtle is a persian rescue and the only lap cat of the bunch.
When she's not working or occupying her small child, she enjoys gardening, reading, riding horses, and has recently taken up sewing.
