Silver City


Hidalgo Medical Services, a federally-qualified health center with 20 years of experience as a frontier and rural training hub, has launched the first Teaching Health Center Graduate Medical Education (THCGME) program in New Mexico as New Mexico’s first Teaching Health Center.


Program Description

Nestled in the heart of the Gila Wilderness, the HMS Family Medicine Residency Program is specifically designed in the “1+2” format to offer top quality training in the urban setting at Memorial Medical Center in Las Cruces, NM during the intern year, followed by a two-year robust, rural, community training experience in Silver City, NM. Decentralizing resident education adds value to the education experience by ensuring that each resident has more community-relevant experiences and training that models the generalist-specialist relationship. At a time when the United States finds itself with an inadequate supply of physicians, the distribution of healthcare and access remains problematic. HMS has developed the HMS Family Medicine Residency Program in response to the primary care needs of our state and nation.  With 20 years of experience hosting rural training rotations, HMS has been recognized by HRSA as the first Teaching Health Center in New Mexico and welcomes two residents per academic year as a 2/2/2 program.


Program Highlights

  • Focus on Rural Training with assistance from other specialties at UNM and telemedicine programs like Project ECHO.
  • Protected Education Time – One day of didactics and scholarly activity per week, focusing on robust lecture topics and activities.
  • Modern Training Facility – Brand new 30,000 Square-Foot facility.
  • Intimate Continuity Clinic Environment – Because the program only accept two residents per academic year, each resident is supported by the entire medical team and guaranteed a well-rounded, full spectrum experience with exposure to diverse and unusual cases.
  • 1.3 Residents to One Faculty Ratio.
  • Unopposed Training with no competition for procedures and full access to Attending Physicians.
  • Richness of Culture – Southwest New Mexico boasts a very diverse population and residents will develop an ability to understand, communicate with and effectively interact with patients across many cultures.

Class of 2020

agueroDr. Roberto Aguero

I was born in Ciudad Mexico; I grew up in New York, completed my undergraduate and master’s degrees in microbiology and immunology in South Carolina, and continued my graduate education in Arizona studying genetics. Afterwards I worked as a research scientist using molecular techniques to address various questions regarding endangered species, as well as the host-microbial interface of the human gastrointestinal tract. I would have to say my favorite research experiences involved field work in the Grand Canyon region of Arizona and throughout Western South America. I’m a very hands-on person and (when time allows) I enjoy wood carving, gardening, and DIY house remodeling. Family medicine was an ideal choice for me and I look forward to the breadth of training as well as serving our new community.


My wife and I are grateful and excited that I matched into family medicine in New Mexico. We have lived in Albuquerque about 15 years and we met while independently following our passions, working with homeless and underserved populations. We consider New Mexico our home. We enjoy the desert southwest with all of the outdoor activities available. My wife, who just graduated with her master’s degree in nursing, will be working as a family nurse practitioner in Silver City. We have a son who will be starting second grade, three dogs and five chickens that all keep us on our toes.
