Ann Calvert

Ann is a graduate of Albion College with a Bachelor of Science Degree and a business minor. Ann joined the staff at Animal Cancer and Imaging Center in 2000. Her Golden Retriever "Popeye" first introduced her to Dr. Obradovich. Popeye had a mast cell tumor in his abdomen and went through a full course of radiation therapy and the cancer was ultimately cured. Popeye lived to the happy old age of 16!  Ann and her husband, enjoy golf and sharing time with family and friends. Ann's favorite perk of the job is meeting and greeting our patients and sending them home with treats. She is affectionately known as the treat ambassador and our patients can't wait to see her!
