Dr. Robert Johnson completed his undergraduate studies in 1974 with his Bachelor’s degree in Animal Science from Pennsylvania State University and then attended the University of Pennsylvania School of Veterinary Medicine, earning his degree as a Veterinary Medical Doctor in 1978. After graduation, he continued his education attending Farrier school and then completing an externship in Large Animal Medicine and Surgery from the University of Georgia Veterinary School. Dr. Bob practiced both small and large animal medicine in multiple settings for over 25 years before relocating to Paso Robles from San Diego in 2008; he still maintains his licensing to practice in six states, but fortunately for us, he now calls Paso Petcare home. Outgoing and exuberant, Dr. Bob has a very loyal clientele that really appreciates his dedication to his profession and his patients. Over the years of practice, he has developed a particular interest in oncology and surgery, finding these cases very challenging.  When not stopping by the clinic on his days off, Bob enjoys many outdoor activities, including his “55 and Better” softball team, hiking, cycling, and kayaking, as well as working with children – often volunteering at his kids’ schools and participating in the “Dad’s Club.” AND, as most people know, Bob is an avid Steeler’s fan!


Dr. Hans Konrad started working at Paso Petcare in June 2021. He grew up in Southern California and received his bachelor’s degree in biology from UC Santa Barbara in 1988. He then graduated with his DVM from UC Davis in 1993. After veterinary school, he initially worked as a large animal veterinarian in Petaluma, then later as a dairy veterinarian in Visalia. For the last 14 years, he has worked exclusively as a small animal and exotic veterinarian.

Dr. Konrad first knew he wanted to be a veterinarian when he nursed an injured turtle back to health at eight years old. As a senior in veterinary school, Dr. Konrad was able to help a sick cow that couldn’t get up while on a farm with some of his classmates. He gave her IV fluids with calcium, and when she promptly got up and starting walking, a farmworker helping him said, “Thanks Doc.” Dr. Konrad was so proud (and this was the first time anyone had called him “doctor”), and he was sure that this was the right job for him.

His professional interests are small animal and exotic animal medicine and surgery; he holds membership to the Association of Reptile and Amphibian Veterinarians and the Association of Exotic Mammal Veterinarians, among others. He is passionate about maintaining and improving the quality of life of all animals, regardless of the species or stage of life they are in. Dr. Konrad and his girlfriend currently have three dogs, three cats, two lizards, four snakes, three tortoises, two turtles and an 11-year-old rabbit. He absolutely loves the ocean and all the activities it allows.

Office Manager

Monica Firchow is Paso Petcare’s office manager. She moved to North San Luis Obispo County in 1997 and it felt like home from the very first day. Previously, she has always worked with people, from preschool to elder care. Now, her focus is on animals and the people who love them. Monica is no stranger to working with animals; she grew up following her dad, a dog show photographer, to dog shows all over the Pacific Northwest, in addition to being around horses, cattle, swine, cats and a few faithful canine companions at home. She raised two kids on the Central Coast; her son and grandchildren live in the Bay Area and her daughter is attending UC Davis. After launching her children into their professional futures, she decided it was time to focus on her own career. Combining her love for two-legged and four-legged creatures made working at the veterinary clinic a perfect fit. Monica has a genuine love for the North County community, and thinks that no matter how much it grows, it’s still a small town filled with wonderful people and their pets.
