Dennis G. Elmer, DVM

Dr. Elmer graduated from Michigan State University College of Veterinary Medicine in 1995 at the tender age of 23. He took advantage of the Veterinary Scholars program to graduate with his bachelors and doctorate in only 5 years.

During his externship Dr. Elmer had the good fortune to travel to Tanzania and to practice Veterinary medicine there. He spent a total of eight years traveling between the States and Tanzania expanding his knowledge of medicine and surgery in each country.

His area of greatest interest has always been surgery and he has spent most of his career honing his skills in the operating theater. Tackling both soft tissue and orthopedic cases with equal vigor, he has been fortunate to provide relief work for some of the busiest veterinary hospitals in the Detroit Metro area. The heavy case loads seen at these facilities allowed him to achieve proficiency with a broad spectrum of surgical procedures.

His love of surgery has compelled him to dedicate himself full time to providing his services to his colleagues in the referral community by joining Advanced Veterinary Care Group. The Care Group has invested in state of the art equipment so that Dr. Elmer can cheerfully tackle the diverse number of surgeries that he loves to perform. The unique partnership between the referring community and the Care Group will allow Dr. Elmer to do what he loves best- fix critters!
