Michael O. Hayes, DVM
I was raised in Northern California, went to UCD as an undergrad and on to Vet School at Davis, graduating in 1982. I moved to Angels Camp and have stayed here ever since. I have raised my two children, Tommy and Chelsea in this environment and love the rural community Angels Camp offers. I like flying float planes, fly fishing, various organized sports and eating. Professionally I enjoy working with all species of animals and my interest is surgery especially orthopedics.
Dr. Ray
Raymond L. Sunseri, DVMI arrived in Calaveras County in June of l980, soon after my graduation from the School of Veterinary Medicine at the University of California in Davis. At that time, I approached my career with a great deal of zeal and passion and after a little more than a quarter of a century later, I still enjoy my calling with the same amount of excitement and enthusiasm.
Mixed animal practice (large and small animal), by its very nature leads to a wide variety of cases on a daily basis, which keeps my interest and devotion to our practice at a high level. This amount of exposure over the years allowed me to pursue and improve my training in areas such as internal medicine, ultrasound, radiology, endocrinology, large and small animal surgery and large and small animal reproduction via the rigors of daily practice as well as continuing education. My formal training started at Cal Poly Pomona, where I obtained an AS degree in Animal Science. I left southern California to attend the University of California, Davis where I received a Bachelor of Science degree in animal science in 1976. Then it was on to the school of veterinary medicine, where I earned my degree in Doctor of Veterinary Medicine in June of l980.
My other passion in life is my family. My wife, Alice, and I enjoy 5 children and 4 grandchildren along with a menagerie of pets, both large and small. We live in Angels Camp, which I have considered my home since the day I arrived over 27 years ago.
Dr. Tom and Family
Thomas A. Heermance, DVMI received my D.V.M. in 2003 from University of California, Davis. I grew up in Palo Alto, California and attended Whitman College in Walla Walla, Washington. My wife Ali and I moved to Calaveras County in the summer of 2003 and I have worked with the Angels Camp Veterinary Hospital team ever since. I have a special interest in surgery and internal medicine. My wife and I live in Vallecito with our daughter Addison, donkey, goats, chickens, dogs and cats. Hobbies outside of veterinary medicine include snowboarding at Bear in the winter and hiking in the summer.
Dr. Ginny
Virginia M. Ringuette, DVMI grew up in Mountain Ranch and worked part-time at Angels Camp Veterinary Hospital while attending Calaveras High School. I received my Bachelor's Degree in Animal Science from Cal Poly, San Luis Obispo. In 2005 I graduated from Kansas State University, College of Veterinary Medicine and spent my first year as a veterinarian in Montana. As much as I loved Montana, I longed to back in this area. I am very excited to be working here again. I enjoy the outdoors and spending time with family and friends including three dogs and two horses.
