Dr. Karla Lombana, DVM, cVMA


Dr. Karla Lombana was born and raised in Salt Lake City, UT and fell in love with horses early on. She started her equine journey in the show ring, and has ridden and shown a variety of horses and disciplines over the years. Owning her own horses was always a priority for Karla, and she is certain that her work ethic and responsibility come from her equine foundation.


Dr. Karla completed her undergraduate education at Willamette University in Salem, Oregon where she double majored in Biology and Science studies, with minors in Chemistry and German. She relocated to Colorado and completed Veterinary School at Colorado State University, graduating in May of 2013. While in veterinary school she performed stem cell research at the Equine Orthopaedic Research Centre. Research has always been intriguing to Karla, and she has been involved in multiple projects and papers, ranging from neuroendocrine pathways to equine stem cell growth. Check out some of the papers here.


Dr. Karla was well aware of the challenges equine specific practice would present, and elected to complete an internship after veterinary school. She selected the internship at Arizona Equine Medical and Surgical Centre in Gilbert, where she met Lindsey.


Dr. Lombana has multiple equine veterinary interests. She enjoys all aspects of routine ambulatory practice, but truly excels at lameness diagnostics and advanced regenerative procedures. Her experience with stem cells and other biological agents is unlike any other veterinarian in Tucson.

In addition to horses Dr. Lombana sees companion animals in the small animal clinic as well. She has a new passion for pets and enjoys all the hands on and advanced diagnostics available for small animals.


Dr. Lombana is also a Certified Veterinary Medical Acupuncturist, and recognizes the benefits of acupuncture in complex cases of any kind.

Lauren C. Thomas, DVM, cVMA

Dr. Lauren Thomas is a Tucson native, growing up in the Marana area, and was exposed to a large variety of animals from a young age.  At first mostly growing up with the various cats and dogs, she joined a local 4-H club and started raising, breeding and showing rabbits, which led to goats and then eventually horses.  After graduating from Marana High School, Dr. Thomas attended the University of Arizona – Go Cats!!, and obtained her Bachelors of Science in Microbiology.  She was fortunate to get accepted and to attend Colorado State University and graduated with her Doctorate of Veterinary Medicine in 2008.  

Dr. Thomas relocated to Flagstaff, AZ and started in a mixed animal practice where she could continue to see the wide variety of animals that she loves.  After 2 years in the cold northern country, she decided it was time to move back home to the desert she loves.  Not finding a compatible mixed animal practice in Tucson, Dr. Thomas entered into a small animal practice serving cats, dogs and ferrets.  She has been practicing small animal medicine for the past 7 years and is very passionate about providing the best care to all her patients.  

Dr. Thomas is also a Certified Veterinary Medical Acupuncturist and loves to combine the arts of alternative medicine with traditional western medicine to help the whole patient.  She became certified through the CSU acupuncture program in 2008 and has been practicing this form of Traditional Chinese Medicine with great success for the past 9 years. 

Currently Dr. Thomas is pursuing becoming a Diplomate of the American Board of Veterinary Practitioners.  The requirements for certification require extensive research and a write up of two medical cases demonstrating specialist level skills and knowledge, as well as complete a rigorous examination to test such knowledge.  She is embarking on this journey to show her dedication to excellence in Veterinary Medicine.  Dr. Thomas enjoys all parts of veterinary medicine, including internal medicine, surgery, dental surgery and radiology, wellness and preventive medicine and more.  

Dr. Thomas is very excited about the opportunity to join Dr. Smogor and Dr. Lombana in their dream of creating a veterinary center that is centered on patient care and close relationships with their owners. 

Outside of work Dr. Thomas is very busy with a wonderful loving husband, 3 great kids, 5 dogs, 2 cats, 2 horses and a box turtle.  Even with all that she can still find time to read a great novel or get in a desert hike or trail ride.
