Meet Our Veterinarians


Michelle DeHaven, DVM

Michelle DeHaven, is founder and proprietor of Cumberland Animal Clinic, selected Best Veterinary Hospital in Smyrna/Vinings in 2009, 2010 and 2011 by smyrnavinings.com.  Dr. DeHaven founded the clinic in 1991 with one employee and a commitment to providing very personal care for pets and their owners.  Today, her successful practice employs a team of 20 professionals, including four veterinarians.  Dr. DeHaven holds a doctorate in Veterinary Medicine from the University of Georgia, along with an UGA undergraduate degree with honors in zoology.  She lives in Atlanta with her husband, their daughter, a golden retriever, and three cats.  In her spare time, she enjoys gardening, cheering on the Georgia Bulldogs, and relaxing at Jekyll Island.

Sydney Tison, DVM

Sidney Tison, has known Dr. DeHaven since UGA Veterinary School, where they sat next to each other and became lab partners.  During their sophomore year, she even introduced Sidney to his future wife, Carol.  Dr. Tison first arrived at Cumberland Animal Clinic in 1996, to help out “for just a while,” and liked the area so much that he has been there ever since.  Like Dr. DeHaven, he has been recognized by Atlanta Magazine as both a Five-Star Veterinarian, as well as a Best Practice member.  He also made a brief appearance on JEOPARDY!, but unfortunately, there was not a column of “answers” concerning just dogs and cats.


Dr. Tamara Fisher, DVM

Tamara Fisher, born a Chicago native, realized as a young child that she had a strong love of animals, and decided to become a veterinarian. After spending a decade in southern California and attaining a degree in Animal Science at the University of California, Davis, she returned to Illinois and graduated with honors in 2003 with a DVM degree from the University of Illinois, Urbana-Champaine. Unfortunately, her acclimation to the mild weather of sunny California fueled her decision to leave the chilly Illinois behind and transplant down to the warmer climes of Atlanta. Dr. Fisher has been practicing in Cobb county ever since, and has been recognized by Atlanta Magazine as a Five-Star Veterinarian. She has a strong interest in internal medicine, dentistry and feline medicine.  In her spare time, she enjoys hanging out with her husband, her 2 year old daughter, and her spunky little tuxedo cat “Xee!”

Dr. Bernadette Riemer, DVM

Dr. Riemer is from Oak Ridge, Tennessee.  She attended the University of South Carolina for her undergraduate studies, and then received her Doctorate of Veterinary Medicine at the University of Tennessee.  After she graduated, she moved to Atlanta to realize her dream of becoming a veterinarian for dogs and cats. When she is not at work, Dr. Riemer enjoys traveling, hiking with her English Setter Rosie, and eating sweets.
