Dr. Michael Little has been practicing veterinary medicine for the past 15 years in the St. Charles community. Although Dr. Little grew up on an Angus cattle and row crop farm in Northeast Missouri, his interests have always remained in small animal medicine and surgery.
In 1993, Dr. Little received his Bachelor of Science from the University of Missouri in Biochemistry. In 1998, he graduated with a Doctor of Veterinary Medicine from the University of Missouri Veterinary Teaching Hospital.

In her free time, Dr. O’Brien loves spending time with family (her husband and two children), as well as her dog, River (a German Shepherd, of course). She looks forward to creating a lasting bond with your furry family member, and to providing the best quality medicine possible.
Dr. Hannah Reller is a recent graduate from the University of Missouri College of Veterinary Medicine (where she also earned a Master’s degree in Public Health). She was born in a small town in Illinois, but received her Bachelor’s degree from Lindenwood University, right here in St. Charles. Though she has grown up around many different species of animals from production to exotics, she has always maintained a specific interest and love for companion animals. Her goal is to improve the lives of pets and their owners through quality medicine, and she is excited to partner in your pet’s care.
In her free time, Dr. Reller enjoys being active with her dog (a perfect brindle Boxer named Ivy), spending time with family and friends, trying new restaurants, and watching her favorite TV shows or reading a good book. She looks forward to coming back to the community and building lasting relationships with her clients and their companions, and is thrilled to join and learn from the Elm Point team.
