Our Staff

Dr. Mike and Technician Cathy

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, DVM - I 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 6 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, DVM- I 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 at Angels Camp Veterinary Hospital ever since. I have a special interest in surgery and internal medicine. My wife and I live in Vallecito with our daughter Addison (6), and son Peyton (4). Our animal family evolves constantly but at the moment includes a donkey, goats, chickens, dogs and cats. Hobbies outside of veterinary medicine include fun at Bear Valley in the winter and New Melones lake in the summer.

Dr. Juliana

Juliana Wurzler, DVM - I was born and raised in Mid-Michigan where frigid winters and humid summers were the norm. At an early age I developed my passion for horses and the care they need through my involvement in 4H and the United States Pony Club. At Albion College, I earned a BA in biochemistry while being highly involved with their Equestrian Center, Kappa Delta sorority, and the Great Lakes Region of the Pony Club. When time came to apply for veterinary school I knew I had to fly the coup and find a good school in a warmer place. I received my DVM from Oregon State University in 2016. While at school I focused my attention primarily on equine medicine but also found that I really enjoyed the internal medicine aspect of my small animal patients. Seeking a mixed animal position after graduation, I found Angels Camp Veterinary Hospital and settled into the area, finding the dry heat of the summer much more enjoyable than the icy winters in Michigan. My partner and I moved to an olive ranch not knowing a thing about the product, other than we like olive oil. Our personal time is predominantly spent tending to the ranch and all of the critters on it which include 2 horses, 3 dogs and 5 cats. My hobbies include horse back riding, exercising, fishing, cooking, gardening and most recently olive ranching.

Dr. Lauren

Lauren Hobstetter , DVM - I was raised in the Bay Area where I grew up with the dream of someday becoming a veterinarian and living in the country with horses in my own backyard. Moving to Angels Camp has allowed me to realize these two lifelong dreams. I moved to Portland, Oregon for my undergraduate studies at Lewis & Clark College where I graduated with a BA in Sociology and Anthropology. I spent a few more years completing pre-requisites for veterinary school at Portland State University and then attended the Oregon State University College of Veterinary Medicine (Go Beavs!) for my veterinary education. My professional interests include internal medicine and pet hospice care. Being a veterinarian is fulfilling because it gives me the opportunity to build meaningful relationships with pets and their people; I'm fortunate to call this my profession. My partner and I share our home with 3 dogs, 5 cats, and 2 horses. When I'm not at the vet hospital, you will find me with my animals, horseback riding, spending time with my family, or taking care of our ranch.

Dr. Jessica

Jessica Sanchez , DVM - I was born and raised in Alaska, where I developed a passion for animals and wild, beautiful country. After a few years working as a wildlife biologist on the California Channel Islands, I decided to pursue veterinary medicine as a way to expand my skills and ability to help animals. I attended veterinary school at the University of California at Davis, then moved to Angels Camp for the opportunity to work at a rural, mixed animal practice with a great team of mentors. I love that every day at Angels Camp Veterinary Hospital is different and gives me the chance to treat a wide variety of species. I've also enjoyed getting to know the people who live in this community, and providing them with high quality veterinary care for their furry family members. I have a special interest in surgery, emergency, epidemiology, and exotic/wildlife medicine. I love traveling, hiking and backpacking, horseback riding, and assisting on wildlife conservation studies.
