  • Stella Barth

    Portrait of Stella BarthI'm originally from Stoneham, MA, and have considered Cambridge home for much of my adult life. I majored in Neurobiology at Harvard College where I was also on the cheerleading team-Go Crimson! After graduating from college, I spent eight years teaching middle and high school science and coaching cross-country in Massachusetts and Connecticut. I then worked as a clinical research coordinator in spinal cord injury at Spaulding Rehabilitation Hospital for three years, which is when I fell in love with Physical Medicine and Rehabilitation (PM&R) and also met my husband. I attended UMass Chan for medical school, where I was part of the Population-Based Urban and Rural Community Health (PURCH) Track at Baystate Medical Center and was a curriculum committee student representative. Soon, I'll pursue training in PM&R at NYU, with a strong passion for neurorehabilitation and medical education leadership. Outside of medicine, I love gardening, kayaking, baking, dancing, and going on adventures with my husband.

  • Cliff De Guzman

    I grew up in San Diego, California, the child of Filipino immigrant nurses whose dedication and strength shaped my outlook on life and service. I attended Pacific Union College in Napa Valley, where I majored in biophysics and participated in advocacy efforts through REVO, a student group dedicated to raising awareness and funds for underrepresented global issues. At Loma Linda University School of Medicine, I developed a deeper understanding of how social determinants influence health and patient outcomes. I'm thrilled to join Cambridge Health Alliance to build a strong clinical foundation and work alongside clinicians who are passionate about delivering high-quality care to those most often left behind by the healthcare system. I'll then begin my training in diagnostic radiology residency at Harlem Hospital Center in NYC, where I hope to contribute to their long-standing mission of equitable care. When I'm not in the hospital, I enjoy staying active by playing volleyball, testing out new recipes, capturing photos, and collecting Pokémon cards.

  • Dhruva Gupta

    Portrait of Dr. Dhruva GuptaI was raised in Charleston, West Virginia, a place burdened by health inequities, where my hometown—often called "Cancer Valley"—suffered from high rates of cancer and limited access to care. This stark reality fueled my commitment to addressing healthcare disparities and sparked my pursuit of medicine. I earned a B.S. in Neuroscience with distinction from Yale College. As I continued my studies at Harvard Medical School, my rotations at Cambridge Health Alliance (CHA) were transformative, where I had the privilege of working with a diverse patient population and witnessing the power of patient-centered, community-driven care. Beyond clinical training, I also explored the intersection of spirituality and healing at Harvard Divinity School and studied ethical AI applications in healthcare. These experiences have shaped my approach to medicine, blending innovation, empathy, and justice. I look forward to my transitional year at CHA and advancing to radiation oncology training at Sylvester Comprehensive Cancer Center at the University of Miami, where I aim to serve diverse patient populations.

  • David Morse

    Portrait of Dr. David MorseI'm David Morse, and I grew up in Knoxville, Tennessee. I studied biophysics at the University of Tennessee, where I discovered a passion for integrating science and medicine. After earning an MPhil in Nanoscience at the University of Cambridge through Fulbright and Whitaker Fellowships, I pursued an MD-PhD between Harvard Medical School, the University of Cambridge, and the National Institutes of Health. My research has focused on developing innovative methods to improve the understanding and treatment of cancer, including nanoparticle-mediated therapies and single-cell genomic assays. I'm currently pursuing my Transitional Year at Cambridge Health Alliance and will complete my residency training in radiation oncology at the Harvard Radiation Oncology Program. I was drawn to radiation oncology for its blend of cutting-edge technology and compassionate patient care. I aim to be a physician-scientist, bridging the gap between research and clinical practice to develop new cancer treatments. I'm particularly interested in tumor genomics and personalized medicine. Joining Cambridge Health Alliance excites me because of its commitment to both innovation and community care. In my free time, I love spending time with my family, hiking, biking, frisbee-ing, gardening, and volunteering to support our community.

  • Amira Osman-Short

    Portrait of Dr. Amira Osman-ShortI grew up in Ann Arbor, MI before moving to and attending high school in Boca Raton, FL. I then moved to Hyde Park, IL where I attended the University of Chicago and received a BS in Cancer Biology. While in Chicago, I volunteered in various global health organizations such as the Atlantis Project, which highlighted the importance of cultural humility in achieving better patient care by promoting trust and improving communication. I also recognized how limited our premedical education was regarding nutrition and its role in disease manifestation and progression. Thus, I attended Columbia University where I received a MSc in Human Nutrition. As a bonus, I also met my husband! I carried the information gained at this program to Boston, where I attended Tufts University School of Medicine. My interest in radiation oncology and the interplay of nutrition and cancer were strengthened here as I navigated challenging patient cases. These experiences helped lead me to Cambridge Health Alliance, where I look forward to solidifying my medical knowledge within a diverse patient population before moving to Palo Alto, CA to complete my radiation oncology residency at Stanford. In my free time, I enjoy spending time with my husband and cat, exploring the outdoors, cooking new recipes, and traveling.

  • Sara Ragi

    Portrait of Dr. Sara RagiI grew up in Upper Saddle River, New Jersey, and developed a passion for science and service while studying Nutritional Sciences at Cornell University. After graduating from college, I pursued a master's degree in Human Nutrition at Columbia University, where I also conducted research on inherited retinal diseases at Columbia University Medical Center in the Tsang Lab. In 2020, I moved to Providence, Rhode Island, to attend The Warren Alpert Medical School of Brown University. During my time at Brown, I became deeply committed to patient advocacy, community health initiatives, and working with underserved populations. I am excited to continue my medical training journey at Cambridge Health Alliance, where I look forward to building a strong foundation in medicine before returning to Brown for dermatology residency. Outside of medicine, I enjoy playing the violin, cooking, traveling, discovering new places for afternoon tea, and kayaking.

  • Michael Zimmerman

    Portrait of Dr. Michael ZimmermanAfter studying accounting at Salisbury University, I transitioned to hospital financial administration at a community hospital in Baltimore. There, I created integrated financial plans that supported both existing community clinics and the development of a new cardiovascular center. My experience shadowing physicians in an HIV clinic combined with my desire to make an impact at a systems level helped cement my decision to pursue medicine, leading me to Duke University School of Medicine. I began postgraduate training in pathology at Columbia University Medical Center, but realized I wanted to work more closely with patients and public health initiatives.

    I'm excited to begin my Transitional Year at Cambridge Health Alliance, where I look forward to developing my clinical skills while working with diverse patient populations. I plan to pursue a career in occupational and environmental medicine, where I can apply my systems-level perspective to improve workplace and community health. Outside of medicine, I pursue my fascination with meteorology, enjoy state and local highpointing, study cartography, and appreciate early twentieth century piano music.
