Veterinarians

Dr. Theresa Driscoll

Owner, Veterinarian

In 1991, Dr. Theresa Driscoll started training her dog for search and rescue operations. By the end of the winter, she realized that while she loved working with animals, training wasn’t what she wanted to do full-time. Cocooned in a snow cave during a weekend training session, something dawned on Dr. Driscoll: becoming a veterinarian was the perfect way to combine her love of animals with a rewarding career!
Dr. Driscoll grew up in San Diego and attended school in northern California for her pre-veterinary requirements. She was accepted into Michigan State University for veterinary school and graduated with the class of 2000. In the spring of 2014, Dr. Driscoll joined the Patterson Veterinary Hospital family.
At home, Dr. Driscoll lives with four pets of her own. Griffin, a Maltese, was one of the pups in the litter of Dr. Driscoll’s first C-Section. Merlin the Havanese is a professional sock thief, and two cats named Oscar and Simon round out the furry portion of the family.
Traveling is Dr. Driscoll’s favorite thing to do when she isn’t caring for pets at her clinic – she absolutely adores meeting new people, learning about other cultures, and immersing herself in history. Rafting through the Grand Canyon and kayaking in Antarctica were two of her all-time favorite adventures.

Dr. Angela Katafiasz

Director of Medicine

When she was very little, Dr. Angela Katafiasz was asked by her parents what she wanted to be when she grew up. She responded that she would like to be someone who plays with animals all day long, so her parents suggested that she become a vet. Dr. Katafiasz never looked back - now, she's a licensed veterinarian here at Patterson Veterinary Hospital!
A native of Ohio, Dr. Katafiasz - Dr. Kat to her coworkers and clients - attended Michigan State University to earn her undergraduate degree in animal science, her doctorate degree of Veterinary Medicine, and a Master's Degree in food safety. She began here at the clinic just after finishing her DVM requirements, and completed her Master's during her first year of work. Medically, Dr. Kat enjoys diagnostic imaging work and the challenge of neonatal care; she suspects that her fascination with infant care stems from her high-school days, when she fostered her very first litter of kittens.
Dr. Katafiasz and her husband - Patterson Veterinary Hospital's very own Dr. Jason Dollman-Jersey - share their lives with three horses, a pair of dogs named Ledell and Leonidas, several cats and a few ducks. When she isn't spending time with her family and pets or tending to the area's animals here at the hospital, Dr. Kat loves cheering on her beloved Michigan State Spartans at every home football game. She also enjoys serving as the veterinarian for the Ingham County Fair, where she gets to dust off her large-animal knowledge and help teach children about animal health and welfare.

Dr. Jason Dollman-Jersey

Associate Veterinarian

Dr. Jason Dollman-Jersey was fascinated by science and animals while growing up, and never stopped looking for books to read or documentaries to watch on the subjects. As he grew older, his curiosity for medicine started to blossom. For Dr. Dollman-Jersey, a career in veterinary medicine allows him to fulfill all of these interests while being able to help others on a daily basis!
Raised right here in Mason, Dr. Dollman-Jersey began his veterinary career at Patterson Veterinary Hospital almost 17 years ago - he came in and shadowed Dr. Patterson when he was younger, and began working as a paid employee shortly afterward. After high school, Dr. Dollman-Jersey headed to Michigan State University to study pre-veterinary medicine and zoology, then earned a second Bachelor's degree in animal science. Finally, he was accepted into Michigan State's veterinary program and earned his Doctorate before becoming an Associate Veterinarian here at Patterson Veterinary Hospital.
Dr. Dollman-Jersey and his wife - Dr. Angela Katafiasz, who is also an Associate Veterinarian here at the hospital - live with many pets of their own. They have two dogs, Leonidas and Ledell, both of whom serve as excellent surrogate parents for the many kittens that Dr. Dollman-Jersey and Dr. Kat foster. The family is rounded out by a trio of horses: Cherokee, an Appaloosa; a paint gelding named Chippewa; and Ivy, a paint mare. Dr. Dollman-Jersey and his wife have also recently added a small flock of ducks to their ranks.
Thanks to his life-long association with the Boy Scouts, Dr. Dollman-Jersey enjoys hiking, camping, fishing, hunting, and shooting in his spare time. He also likes reading a good book and enjoying craft beer.

Dr. Julie Robinson

Associate Veterinarian

Dr. Julie Robinson spent a lot of time on her grandparents' Saline, Michigan farm while growing up, and it was there that her adoration for animals was born. Her life-long fascination with science, the natural world, and the intense bonds between humans and animals made one thing very clear: Dr. Robinson was destined for a career in the animal-care industry! She's been a member of the Patterson Veterinary Hospital team for over a decade.
Dr. Robinson is from Ann Arbor, Michigan, and received Bachelor's and Master's degrees in the liberal arts from the University of Michigan. Just before she planned on starting law school, Dr. Robinson spent a semester teaching at a school for field studies, which reminded her of her innate love for science. The pull of the veterinary field didn't let up - Dr. Robinson decided to change her path and signed up for veterinary school shortly thereafter.
Dr. Robinson joined the Patterson Veterinary Hospital family in 2004. She's especially fond of doing behavior consultations to make pet owners' lives more enjoyable, exploring and supporting the human-animal connection, and using alternative care methods to improve pets' quality of life. Most of all, she likes developing personal relationships with clients and their pets to facilitate a true bond between caregiver and pet owner.
In her time away from work, Dr. Robinson enjoys hiking, swimming, biking, and practicing yoga. She lives with her husband and five children; as a family, they enjoy traveling, playing together, cooking, and gardening.

Dr. Carolyn Scholl

Associate Veterinarian

Dr. Carolyn Scholl graduated from Ross University School of Veterinary Medicine, located in St. Kitts, West Indies, in September 2008. She completed her undergraduate studies in Zoology at Michigan State University in 2004. She worked at a clinic in Kokomo, Indiana prior to starting at Patterson Veterinary Hospital in August 2013. It has been quite an experience watching the clinic grow and make nay improvements over the last few years. She enjoys practicing veterinary medicine and surgery with the assistance of a dedicated and caring staff. When she is not working with animals, she enjoys swimming, biking, and running as well as participating in triathlons and bike tours. She also serves the country in the US Army Reserves Veterinary Corps. Dr. Scholl shares her hole with a small dog, named Elvis, and two cats, named Anna Belle and Willie.

Dr. Anne Fitzgerald

Associate Veterinarian

Growing up in Ann Arbor, Michigan, Dr. Anne Fitzgerald was exposed to medicine and animal care very early in life. Her father was a pathologist, and her mother taught environmental education and served as a small-scale wildlife rehabilitator. For Dr. Anne, a career in veterinary medicine simply felt natural!
In the late 1970s, Dr. Fitzgerald was fortunate enough to spend a summer with one of the first women to practice veterinary medicine in Michigan - Dr. Suzanne Jacoby, a refugee from the Holocaust and one of the most inspirational people Dr. Fitzgerald has met. After her adventures alongside Dr. Jacoby, Dr. Fitzgerald was accepted into Michigan State University's veterinary program to earn her Doctorate. She spent two years after graduation in mixed practice in New Hampshire (where pulling porcupine quills out of pets was a regular occurrence). three years in small-animal work in Pennsylvania, five as the University Laboratory Animal Veterinarian at Purdue University, and 15 years in human drug research and development at the Pfizer corporation in Ann Arbor. After hearing from a neighbor that Dr. Patterson needed some help around the clinic, Dr. Fitzgerald joined the hospital team in 2009.
Dr. Fitzgerald is board-certified by the American College of Laboratory Animal Medicine, and has had specialized experience and certification in toxicology. She particularly enjoys ophthalmology and cardiology work, and loves the fascinating relationships between pets and their families.
Dr. Fitzgerald and her husband, who works as a veterinary pathologist, have one grown daughter and live with one pet of their own: Sammy, a Pembroke Welsh corgi who enjoys chasing semi trucks. In her time away from the clinic, Dr. Fitzgerald enjoys reading, birding with her husband, walking Sammy, and enjoying beautiful northern Michigan. She has a love-hate relationship with knitting.

Dr. Catherine Collins

Associate Veterinarian

Dr. Catherine Collins lived behind a veterinary clinic while she was growing up, and was always fascinated by the work that was performed there. She was also exposed to the animal-care industry thanks to her mother's small dog boarding and grooming business. Combined with a natural love for the sciences, Dr. Collins' early pet experiences led her to one conclusion: a career in the world of veterinary medicine was her true calling!
Dr. Collins attended Michigan State University to receive both her undergraduate degree and Doctorate of Veterinary Medicine. She fell in love with Lansing immediately, and has wanted to stay in the area ever since! Dr. Collins joined the Patterson Veterinary Hospital family in August of 2015, and holds special interest in surgery. For her, every day brings a new challenge - there are always fresh opportunities to learn and grow.
Most of Dr. Collins' free time is occupied by her and her husband's toddler, he family's cats, and crazy dog. When she does have a spare moment, she is an avid exerciser and even runs triathlons. The biggest race Dr. Collins has done so far was the International Triathlon event in Chicago, which she ran when she was 17 weeks pregnant!

Jess

Business Administrator

Veterinarians were Jess’s heroes while she was growing up – after all, they made her best friends feel better. Jess has been interested in the field of veterinary medicine for as long as she can remember, and she’s thrilled to work firsthand with veterinary professionals and loving pet owners alike as the Business Administrator of Patterson Veterinary Hospital!
Originally from Dansville, Michigan, Jess was heavily involved in the 4H club while growing up and spent a lot of time showing horses, which helped spark her love of animal care. She attended Lansing Community College before transferring to Baker College to study veterinary technology. Before long, she started taking more classes in the business and human resources fields, which she found she had quite the knack for. Jess finished her degree just as the Practice Manager position was opening up here at Patterson Veterinary Hospital, and she’s happily filled that role since 2009.
Outside of work, Jess spends most of her time with her daughter, Amelia. She also shares her home with Krieger, a German Shepherd who loves making friends with everyone, and Soloman, a Maine Coon who would eat his weight in food if he was allowed.

In August 2017, she began working at Patterson Veterinary Hospital as a receptionist and has been loving the position since. Anna has a passion for not only protecting our natural lands, but our furry friends too. In her free time Anna enjoys camping, hiking, and photography.
