Rich A. Carlson,
D.V.M., ABVP

Rich A. Carlson,

Diplomate, American Board of Veterinary Practitioners,

Certified in Canine and Feline Practice

Dr. Rich Carlson thoroughly enjoys working as a veterinarian. Becoming a veterinarian was his dream as a young boy, and he feels so fortunate to have spent the last 30+ years helping people and their pets. After graduating from the University of Illinois, he founded Carlson Animal Hospital in Oak Park in 1980 in a 900-square-foot dry cleaner space. Carlson Animal Hospital grew quickly, and a few years later Dr. Carlson bought and renovated his current 3,200-square-foot, state-of-the-art building. The facility won the American Animal Hospital Architecture top award for the best re-use of a building and was awarded the Cavalcade of Pride Award by the Village of Oak Park.

Dr. Carlson earned the title "Diplomate" when he became board certified in canine and feline practice through the American Board of Veterinary Practitioners (ABVP) in 1987. This is a respected and fully accredited board designation for veterinarians who demonstrate expertise in a broad range of clinical subjects. He is one of small group of 900 ABVP Diplomates in the United States and abroad. ABVP Diplomates undergo a very long and very difficult process of additional study and examination to become a board-certified specialist. ABVP Diplomates have proven knowledge and expertise above and beyond what is required to practice veterinary medicine. Dr. Carlson has a special interest in internal medicine, ultrasound, endocrinology, oncology, dermatology, and infectious diseases. He is academically oriented and has published several scientific papers in peer-reviewed veterinary medical journals. He also wrote a pet health newspaper column for 15 years and served on the credential committee for the Feline Specialty Board for many years. He enjoys mentoring and training young veterinarians and staff.

Over the last 10 years, Dr. Carlson has invested in state-of-the-art noninvasive technology such as digital radiography, digital ultrasound, digital dental radiography, and computerized medical records to better serve his patients. This high-end technology has revolutionized the practice of medicine. Dr. Carlson and his staff are excited and proud to offer this to patients. He feels privileged to be part the community and his clients and pets’ lives and has truly enjoyed getting to know them.

In his free time, Dr. Carlson enjoys spending time with his family and his own pets, Zoe and Julio, as well as his grandpets, Andre, Sloopy, Minnie, Bella, and Cody. He also enjoys traveling and working out at the health club.

Traci Lazar,

Traci Lazar,

Dr. Traci Lazar (Leslie) received her bachelor’s degree in animal sciences, as well as her Doctor of Veterinary Medicine training, at the University of Illinois in Urbana-Champaign. She has volunteered and worked at a number of local animal shelters, emergency centers, and through the university as a technician, kennel assistant, emergency radiology technician and a surgery technician. Two of her most memorable and educational experiences include traveling to Africa for a month to work for Vets-in-the-Wild, as well as working with Rural Area Veterinary Services in Washington State to assist in spay/neuter and wellness clinics throughout the state’s various Indian reservations.

Dr. Lazar started working at Carlson Animal Hospital immediately after graduating from veterinary school. She is originally from Park Ridge, Illinois, and loves being close to home. She has a black Lab/pit bull mix named Parker who she adopted when he was six months old. Now he is an old man and enjoys a life of luxury involving neighborhood walks, afternoon naps, treats, and more naps. She is married, and has enjoyed watching the bond form between her husband (who grew up with cats) and Parker. They enjoy living in Logan Square and taking advantage of all it has to offer.

Dr. Lazar has wanted to be a veterinarian since she was five years old and nothing could change her mind. Fortunately, she thoroughly enjoys science and continuing her education. At this point in her career, she is focusing on expanding her knowledge in internal medicine and abdominal ultrasound, soft tissue surgery and continuing to grow in the field of veterinary medicine every day. In her free time, she enjoys being outdoors as much as possible, training for half marathons, biking, kayaking, traveling the world and trying new cuisine with her husband.  She is very grateful for the support of the staff and continuing mentorship and guidance of her colleagues at Carlson Animal Hospital, and feels like she has truly found a home here.

Cheryl Toncray,
D.V.M.

Cheryl Toncray,

Dr. Cheryl Toncray moved to Chicago in 1992 as a young veterinarian and began working full time at Carlson Animal Hospital. She received her veterinary degree in 1990 with honors from Michigan State University. She was specifically attracted to the high level of compassionate care and progressive state-of-the-art medicine practiced by Dr. Carlson and his staff. Her specific interests are in internal medicine and most recently elderly/hospice care for the senior pet. While at Michigan State University, she was the recipient of the International Veterinary Student Group African Exchange fellowship and was chosen by the University to be in a featured article in Michigan Women magazine.

Prior to joining the staff at Carlson Animal Hospital she practiced veterinary medicine in Toledo, Ohio for 2 years. When first moving to Illinois she lived in Oak Park where she was an active member in the community through her work at the hospital, her local church, and as a member/violinist of the Oak Park/River Forest Symphony. In the past years she and her husband Tim decided to expand their family beyond the 2 dogs, 4 cats, and rabbit they started their married life with. Adding their 2 daughters led to working fewer hours at the hospital, however, she has remained an active member of the staff.

She is extremely excited about the advancements made in veterinary medicine over the 20+ years she has been working at Carlson Animal Hospital. She is fortunate to be working these many years with Dr Carlson, the staff at Carlson Animal Hospital and the patients and clients she sees on a daily basis where she is able to practice and provide advanced medicine and surgery to our wonderful companions. In her time away from the hospital she loves to travel, perform her music, and spend time with her active family.

Emily Rehm,
D.V.M.

Emily Rehm,

Dr. Emily Rehm joined Carlson Animal Hospital in 2019 after graduating from the University of Illinois College of Veterinary Medicine. After spending 8 years in Champaign to complete her bachelor and veterinary degrees, she is excited to be back near Chicago. Dr. Rehm grew up in Skokie, IL and fell in love with veterinary medicine while volunteering for a local animal shelter. Her experience then ranged from nutritional and cognitive research to working with calves and piglets, and spending time with a small animal clinic in between. Her interests include feline and geriatric medicine. 

Dr. Rehm grew up with dogs her whole life, but realized her love for cats after adopting her first cat freshman year. She currently lives with Abner, an older, long-haired tuxedo-colored gentleman, and Louie, a newly adopted Maine-coon mix. Although she loves working with cats and wishes she could adopt them all, Dr. Rehm cannot wait to have a backyard someday and adopt a big dog of her own.

In her free time, Dr. Rehm enjoys spending time with family and friends. She loves trying new restaurants, heading to the movie theater, and hiking when the Illinois weather allows it. She is very grateful for the opportunity to work at Carlson Animal Hospital and looks forward to providing compassionate, high quality medicine to companion animals and their families.
