Managing Veterinarian

It makes perfect sense that Dr. Mallen would become a veterinarian — after all, she quite literally grew up in the clinic! She developed a love for animals and the practice of veterinary medicine at a young age. Her mother, Dr. Phyllis Frost-Strain, opened the Avenue of the Saints Animal Hospital — one of the two practices incorporated into our current clinic — in 1995, and she still practices at Avenue Veterinary Clinic today.

Jami grew up a few miles outside of Plainfield, Iowa. She started her veterinary career as a Technician at Avenue of the Saints Animal Hospital in 2007, gaining valuable experience in veterinary school. She completed her undergraduate studies at Wartburg College, majoring in Biology, before getting her DVM degree from Iowa State University’s College of Veterinary Medicine in 2014. Upon graduation from veterinary school, Dr. Mallen quickly transitioned into a position alongside her mother.

Dr. Mallen has a special passion for internal medicine and loves the problem-solving approach it requires. She especially enjoys doing abdominal ultrasounds. She also loves conducting new-patient exams and helping pet owners seamlessly transition their new furry friend into the home. Since introducing dental radiographs, she has also developed a great appreciation for dentistry and maintaining your pet’s oral health.

Outside of her veterinary interests, Dr. Mallen loves being active outdoors with her family by four-wheeling, kayaking, hiking, and traveling across the United States in their RV. She also enjoys do-it-yourself projects around the home, especially when she can turn an old, tattered item into something beautiful. Jami also likes to read and quilt when she gets the chance. Jami is married to her wonderful husband, John, a Regional President for Woodruff Construction. They have three children: Harper, Addyson, and Caden. Together, they have a Bernese Mountain dog, Beau, and five cats, Carson, Dice, Honey, Minnie, and Felix.

When asked which dog breed she identifies most with, she chose a Labrador Retriever. However, she would not own one because she prefers a mellow, lazy dog. Like a Lab, she is athletic, loyal, friendly, enthusiastic, happy, and intelligent.

Veterinarian

Dr. Mack has pretty much always known she wanted to be a veterinarian! She has had cats since she was born, then gradually added dogs, hamsters, gerbils, fish, and reptiles. When she was five years old, she discovered what a veterinarian was, and at that moment, she knew she could be nothing else! She obtained her undergraduate degree at Truman State University in Kirksville, MO, and then attended veterinary school at Iowa State University. She is now licensed to practice medicine and write health certificates in Iowa. Dermatology and behavior are her special areas of interest in veterinary medicine. She would love to learn more about dentistry and nutrition.

In her free time, Dr. Mack enjoys reading, baking, swimming somewhere warm, and walking. Dr. Mack has a husband named Josh, who doesn’t realize there are only 24 hours in a day, so he takes on many endeavors and projects! She has four children: Carter, Lucas, Madison, and Charlotte. Dr. Mack also has a black Labrador Retriever (who can sometimes be seen around the clinic) named Cosmo and four domestic shorthair cats named Monkey, Charlie, Midnight, and Snickers.

When asked which dog breed she resonates with, Dr. Mack chose a Golden Retriever because they’re friendly with everyone, have a happy personality, and are easygoing.
