Our Doctors

Mesa's Veterinarians 


Dr. Patrick SmithDr. Patrick Smith

     Dr. Patrick Smith graduated from the Ohio State University College of Veterinary Medicine and came west with his wife, Sandy, to help start this practice when the doors opened to a much smaller Mesa Veterinary Hospital in June, 1974. He enjoys behavioral medicine and surgery along with all facets of getting along with people and their pets. He spends a lot of his "spare" time on the computers at the hospital, keeping things up to date. The Smith family, including two adult sons who live in Colorado, all enjoy anything to do with living in the mountains west of Denver including skiing, hiking and building a house.

Dr. Stefan RachwalDr. Stephan Rachwal

     Dr. Stefan Rachwal came to us as a student at Wheat Ridge High School. His intelligence and love of cats "forced" us to keep track of him throughout college at CSU and then keep him as a veterinarian when he graduated from CSU's College of Veterinary Medicine in 1984. He became an owner of Mesa Veterinary Hospital a few years later and has kept his special interest not only in cats, but also in any part of internal medicine. He is our "walking book of knowledge!" For the past ten years, he has been recognized by the Colorado Academy of Veterinary Practice, which means he gets more than 50 hours of Continuing Education per year.  He likes biking and working out downtown at the gym. Stef has participated in the Pet Loss Support Committee and other elected positions for the Denver Area Veterinary Medical Society for well over 20 years and we support him totally in this important endeavor.

Dr. Steve BatchDr. Steve Batch

     Dr. Steve Batch is a high school classmate of Stefan's from Wheat Ridge High School and we met him at about the same time. (Lots of stories there!) Steve went to an internship out in West Los Angeles after he graduated from the College of Veterinary Medicine at CSU. After an intense year in California, he and his wife, Martha, came back to us in 1984. They have 2 beautiful daughters here in Colorado and they live in Arvada. He is one of the four owners of Mesa Veterinary Hospital, and has been instrumental in our tremendous growth and success. Steve has special interests in everything, but especially internal medicine, surgery and oncology. He handles a lot of our exotics cases as well.

Dr. Christine HorstDr. Christine Horst

      Dr. Christine Horst, also one of the owners of Mesa Veterinary Hospital, came to us in high school, during an honors externship program from Kent Denver. We recognized her skills and intelligence and kept in touch with her throughout college and even after she graduated from the CSU College of Veterinary Medicine. After working in a small animal and exotic practice in Phoenix, she came back to MVH and we are really pleased she did! She handles most of the exotic animal work at the practice (along with Dr. Batch) and she loves working with the puppies and kittens too! She and her husband, Wade, spend nearly all of their free time on bicycles and have even had the good fortune to do the Leadville 100 and 24 hours of Moab. They have welcomed their sons, Zak and Josh, into the world since she has been working at MVH.  They also share their home with a Bernese Mountain Dog named Cartman and Chase, an Australian Shepard. 


Dr. Kitren NickersonDr. Kitren Nickerson

    Dr. Kitren Nickerson was a wonderful addition to the Mesa Family. She graduated Magna Cum Laude from CSU in 2001 after receiving her Master's Degree there in 1997 in Physiology. She originally graduated with her B.S. from Cornell University, but her love for Colorado brought her back home to go to school. Kit and her husband, Matt, love every aspect of working and living with animals as evidenced by their own special herd of dogs, cats and a horse. She spends most of her free time with her horse, Schuyler, training and competing in the sport of eventing. Kit has tremendous energy and enthusiasm and has helped make MVH one of the top veterinary hospitals in Denver.

Dr. Suzanne TousleyDr. Suzanne Tousley

    Dr. Suzanne Tousley was born and raised in Detroit, Michigan. After graduating from Michigan State University with a BA in interior design, she moved to Denver and worked in design for 5 years before returning to her interest in medicine. She went on to graduate from the College of Veterinary Medicine at CSU and performed a full year internship here in Denver, rotating through surgery, internal and emergency medicine. Suzanne loves the veterinary field as it is always changing and consistently challenging. She lives in Golden with her high-energy family - husband, Tony; daughter, Taya; and 2 dogs, Stuka and Joey. She has taken up road bicycling after all those years of watching Tony compete in triathlons and they spend as much time as possible outdoors.


Dr. Joshua BubDr. Joshua Bub

     Dr. Joshua Bub came to us from Florida where he practiced in a small animal hospital in Tampa. He graduated from the University of Florida with a degree in Zoology and a minor in Business Administration in 2004, and then stayed at UF to graduate with his DVM in 2008. He graduated Cum Laude with both degrees. Josh moved to Colorado in 2011 with his then fiancée, Rebecca, when she matched at a family medicine residency in Denver. They have since fallen in love with Colorado and were married in the mountains in September 2011.  They now live in Golden with their 2 dogs, Alli (a Shepard/Lab mix) and Emma (a Golden Retriever), and cat, Loki. Josh and Rebecca enjoy hiking (and plan to climb every 14’er within the next few years), skiing, biking, and avidly following Florida Gator and Michigan State Spartan sports.
