Our Veterinarians
Dr. Micah Hartwig, DVM
Dr. Hartwig brings over two decades of veterinary experience and a deep love for animals to her role as the newest veterinarian at Acorn Hill Animal Hospital. Graduating from Oklahoma State University in 1998, Dr. Hartwig embarked on her journey in veterinary medicine, fueled by a passion for animal wellness and preventive care.
With a background that includes owning her own clinic in Tulsa, Oklahoma, Dr. Hartwig is a seasoned practitioner dedicated to the well-being of her furry patients. Her expertise spans a wide range of areas, from allergy management to soft tissue surgery.
Dr. Hartwig and her husband, both die-hard OSU Cowboys fans, moved to San Antonio to be closer to family. They share their lives at home with a lively menagerie of animals, including two Labrador Retrievers, a Chihuahua, five cats, and five beloved horses. Whether she's playing tennis, spending time with her horses, or cheering on her two college-age daughters, family remains at the center of her life.
Dr. Lauren Keim, DVM
Dr. Keim brings a unique blend of expertise and heartfelt dedication to her role as a veterinarian. Born and raised in El Paso, Texas, Dr. Keim's journey in veterinary medicine has taken her across the United States. After completing her undergraduate studies at UTSA, Dr. Keim pursued her doctorate at St. Georges University in Grenada, with her final year of training at Oklahoma State University. This diverse educational background has equipped her with a comprehensive understanding of veterinary medicine and a deep appreciation for the human-animal bond.
At home, Dr. Keim shares her life with two beloved lab mixes, Chili and Swagger. Chili, found on the beaches of Grenada during her studies, and Swagger, rescued from her hometown of El Paso, hold a special place in her heart. Dr. Keim's passion for animals extends beyond her professional life, as she enjoys spending time with her dogs and taking them to the river for outdoor adventures.
