Dr. Amber Wolf-Ringwall is a board-certified veterinary oncologist. She grew up on a farm near Dickinson and attended Colorado State University where she received her BS and PhD in Biomedical Sciences. Dr. Wolf developed a passion for veterinary oncology and cancer research when her two young dogs developed lymphoma, which led her to pursue veterinary training. She received her DVM from Colorado State University in 2014, completed her rotating internship at North Carolina State University, and 3-year medical oncology residency at the Flint Animal Cancer Center at Colorado State University. Dr. Wolf most recently served as faculty and section head of the clinical oncology service at the University of Minnesota.

Dr. Wolf has a special interest in hematologic cancers such as lymphoma and leukemia, palliative cancer care, and comparative oncology. She is excited to return to North Dakota and join the RRAEH team to provide compassionate cancer care to companion animals in her home state and surrounding area. Dr. Wolf enjoys spending time with her husband, their dogs Violet and Sisu, hiking, traveling, cheering on the Denver Broncos, and spending time with family and friends in North Dakota and Minnesota.

Dr. Wolf-Ringwall and her team see patients Tuesday – Wednesday at RRAEH by referral/appointment only. Please speak with your veterinarian about submitting a referral through the RRAEH Referral portal or give us a call at 701.478.9299.
