Brad Dempsey, MD, grew up in New Mexico, where he earned a degree in Biology and Foreign Languages as an undergraduate. He speaks Spanish and Portuguese. He subsequently completed medical school in his home state of New Mexico, and trained in Lincoln, Nebraska with the LMEP residency program in Family Medicine.

After residency he worked in a rural Federally Qualified Health Center in Southern Colorado. He has travelled throughout Latin America with global health groups, including Amigos de las Americas and Unite for Sight, which created formative experiences that led him into Medicine.

He enjoys working at SCFM because of the broad scope of experiences and the opportunity to interact with resident physicians. He is currently working on practice transformation initiatives to keep up with the rapid changes in Medicine, as well as helping develop the geriatric care curriculum. In particular, he would like to implement screening protocols into our daily outpatient practice as well as collaborate to integrate behavioral health seamlessly into office visits to provide a model clinic for residents. He enjoys improving efficiency in treatment protocols and EMR workflow.

He is happily married to Leslie Dempsey, MD, who is also a faculty physician with SCFM, and together they have a son.

Dr. Leslie Dempsey, and her husband Dr. Brad Dempsey, moved to Pueblo, CO, and joined the SCFM faculty in the summer of 2015. While new to the teaching role she loves shaping the future of family medicine through its next generation of doctors. Her passion is for multi-generational and whole family care and this includes obstetrics and lactation support. Dr. Leslie is also on track to perform cesarean sections for our clinic patients at St. Mary-Corwin hospital, which will improve our obstetric curriculum.

Originally from a small town in northern New Mexico, Dr. Leslie has pursued a career in medicine from a young age with plans to be a rural family medicine, “do-it-all” kind of doctor. She attended Texas Tech University and has a BS in Animal Science. This allowed her to hold on to her country roots while still getting prepared for medical school. Then it was on to Paramedic school in Colorado Springs for a year and later medical school in Albuquerque, NM at the University Of New Mexico School Of Medicine. There she met Brad Dempsey and they married in 2009.

With full scope medicine still the goal, Drs. Leslie and Brad Dempsey moved to Lincoln, NE for residency. Upon completion and board certification they spent two years serving in a federally funded health clinic in La Junta, CO. There, Dr. Leslie had the privilege of providing care to those who most needed it, gaining practical experience and knowledge along the way. She practiced inpatient, outpatient, nursing home/geriatric and obstetrical medicine in a rural hospital.

Her time on her parents’ dude-ranch gave her an appreciation for hard work and family balance and she strives to maintain that balance today. Therefore, after the birth of their son in 2014, Drs Brad and Leslie Dempsey changed their focus from rural medicine to academic medicine and are enjoying all that this new practice style and city have to offer.

In their free time the Dempseys try to visit family as much as possible, hike or bike in the nearby mountains, swim (any water activity is Nolan’s favorite), or spend quality family time at the zoo, children’s museum or other local attractions. Dr. Leslie can’t wait to own horses again and teach her family to ride!

Dr. Stein joined the faculty in January 1996. After doing Locum Tenens for 2 years she feels very fortunate to have found such a great group of people to work with for so long.

Together, with Dr. Sergio Murillo (a former SCFM resident), they supervise residents at the Avondale Los Pobres Center every Thursday. She is also one of the few part-time faculty who has a part-time private practice in town.
