A Successful Society Requires Decisive Leadership

As with any volunteer organization, strong leadership is essential for success. During July of each year, the Pima County Medical Society Elections Committee meets to begin the task of recruiting officers, Board of Directors, Resident and Student candidates.  Election ballots are then mailed to vote-eligible members. Winning candidates are announced at our December Board of Directors meeting.  Terms vary depending on the leadership position.

Members interested in playing a personal and more active role in the direction of the Society and organized medicine should seriously consider running for office.  If interested or have any questions, please contact Executive Director Dennis Carey at

“As a public health nurse implementing high-risk mother-Infant follow-up programs, then as a school health nurse, and Nursing Supervisor of a long-term care facility, taught me what a powerful role community health played. My experience on the Thai-Cambodian border in a refugee camp, reinforced the importance of communicable diseases and world health. In the past few years, I have been an active practitioner, administered medical practices, and developed an understanding of Specialized Physicians, Hospital Systems, the complexities of the business of everyday physicians including documentation, IT, credentialing, certifications, regulations, EMR, billing and insurance interfacing.

“I view PCMS as a collaborator of all levels of health care work including private and public sectors, all socioeconomic levels, including the needs of the homeless and shelters, bridging and supporting physicians with upcoming changes in IT, political regulations, essentially any changes affecting their day-to-day patient care flow.  Also, to proactively and operationally interface with any platforms to support physicians legally, politically and economically.

I worked as a Public Health Nurse prior to attending medical school, so I have knowledge and an appreciation of how both local and distance disease ultimately affects us all.  I have traveled and worked abroad in a Refugee Camp on the Thai-Cambodian Border, so have an understanding of infectious disease and cultural diversity issues.  My private practice was culturally diversified.”

Gabriela Orozco

.I am a first-generation immigrant from Colombia pursuing a career in medicine to serve underrepresented communities and improve systemic conditions, so individuals everywhere can receive the help they need. I have been living in Tucson for 6 years and consider Pima County my home. I attended the University of Arizona as an undergraduate student and received a Bachelor of Science in Physiology as well as a Bachelor of Art in Spanish Literature. Currently, I am a second-year medical student at UA College of Medicine. In the past year, I have served as a Clinic Coordinator for Shubitz Family Clinic, a free primary care clinic at the College of Medicine that aids in addressing health disparities concerning access to high-quality and affordable medical care. Additionally, I focused my research on prioritizing the principles of justice, equity, diversity, and inclusion in artificial intelligence technologies for cancer control to prevent exacerbation of existing health disparities.

As Student Representative, I aim to represent the student body at the University of Arizona College of Medicine and improve communication between students, physicians, and other medical professional in Pima County. As I work toward my medical degree and grow as a healthcare provider, I want to continue serving my community, especially those are most vulnerable, so we can advance health equity within a broader context of patient diversity and social justice. Through Pima County Medical Society, I believe all levels of health care can collaborate to address the needs of our community and make a real difference.

Nandini Sodhi

As I begin medical school, I know the journey to becoming a physician is long and full of turns. But I hope to always remind myself of my “why” whenever I feel lost. My “why” is service. Caring for patients who otherwise would be at risk to go without care. Bridging the urban – rural health care disparity in Arizona, through service and policy changes. This is my “why.” And Pima County is my community, and I want to better understand it through working with mentors and the medical community. As a board member of the PCMS, I hope to work together to bridge accessibility gaps and ensure physicians are heard and given the resources they need.

In my free time, outside of medicine, I enjoy watching movies, spending time with family and traveling. My favorite recent place I travelled to was Flagstaff. I enjoyed the beautiful hikes, old-timey downtown and cooler weather.

Adam Thompson

I was born and raised in Arizona. I completed two bachelor’s degrees in Applied Biological Sciences and Psychology, a certificate in Cross-Sector Leadership and a Master of Science in the Science of Health Care Delivery with an emphasis in health policy. Currently, I am a first-year medical student at the University of Arizona College of Medicine Tucson. My interests within the health care field include the intersection of maternal/child health and health policy. I have local institutional policy experience changing the way Registered Dietitians screen for postpartum depression at my local WIC clinic, state-level policy experience interning for a Maricopa County Board of Supervisors candidate as a health policy adviser, and federal policy experience publishing in Health Affairs on food insecurity in college students during COVID-19 and doing research on federal farm to school programs and how federal school policy impacts childhood obesity. In addition, I have worked in a pediatric breastfeeding clinic as a scribe and was the Director of Client Services for the Phoenix Cancer Support Network, where I have worked with underserved patients all over Arizona connecting them to various community resources.

As a medical student, I intend to continue my work in health policy and advocacy as President of UA’s American Medical Association and Co-Founder and Policy Chair of the Health Policy & Advocacy club at my medical school. I am currently working on creating policy writing workshops for medical students to be able to translate their advocacy work into publishable pieces and continuing my research on childhood obesity policies such as farm to school. Additionally, I am the Lead Coordinator for UA medical school’s free LGBTQ+ clinic, where I will be leading the effort to provide free health care and address the social determinants of health in this vulnerable community. I would be honored to have your vote for the opportunity to serve as Student Representative on the Board of Directors for Pima County Medical Society and expand my impact in policy and advocacy to Pima County at-large.
