Dr. Rebecca Rogers began her physician journey as a medical student at Harvard Medical School, the first physician in her family and not knowing what kind of doctor she wanted to be. After witnessing firsthand the intimate and longitudinal relationships that are forged between patients and their PCPs, the range and depth of clinical knowledge required of the general internist, and the excitement and uncertainty that a seemly average day at the clinic can bring, it became clear that becoming a primary care physician was the path for her.

After finishing medical school she did research at the London School of Hygiene and Tropical Medicine, studying how primary care systems can deliver public health services. It was an eye-opening experience to learn about the UK’s National Health Service, to see how medicine operates in a world where access to affordable health is guaranteed to everyone. Dr. Rogers returned from London to do her residency here at CHA, where she was awed by the commitment of her faculty and co-residents to CHA’s mission to provide high quality care to the most marginalized populations. She became interested in resident continuity clinic as an educational entity, and during residency she led a pilot project of resident-to-resident hand-offs between ambulatory blocks. During her chief resident year at CHA, Dr. Rogers took part in the Harvard Macy Program for Post-Graduate Trainees. Through that course she developed a curriculum to help interns learn the skills required to be effective, efficient and resilient primary care doctors, which she continues to teach and mentors others in similar teaching.

Dr. Rogers took her first job out of residency as a primary care doctor at CHA, where her daily interactions with patients continued to inspire her to become a better clinician and to advocate for health and social systems that truly care for those that need it most. She joined the program leadership as an Assistant Program director for ambulatory education in 2017 and then as Program Director in fall 2023. During this time she has published and presented work (often partnering with residents) on a community-based orientation activity, improvements in screening for food insecurity, mental health skills for general internists, as well as several ambulatory-based educational innovations. She is thrilled to be inspiring the next generation of curious, compassionate, and mission-driven internal medicine physicians and health advocates.

On the homefront she is wife to a high school teacher in-training, mom to two school-aged boys (human) and two geriatric boys (feline), a bike commuter, tofu lover, and backyard birder.

Dr. Priyank Jain graduated from medical school in India at All India Institute of Medical Science in New Delhi. He completed his internal medicine residency at Medical College of Wisconsin in Milwaukee. Then he went to India for a year and worked in a variety of healthcare settings including remote villages and metropolitan hospitals, and this changed his conceptualization of health, disease and illness. He no longer sees illness as an accident, but rather a culmination of socio-economic conditions affecting communities. 

He believes that the ultimate duty of physicians is to advocate for their patients. To this end a physician has to continue to hone their clinical skills and rapidly evolving medical knowledge and therapeutics, listen carefully to understand what the patient values, and collaborate effectively with the interprofessional team to achieve those patient centered goals. More often than not, clinical decisions have to be taken with incomplete information about the disease and the treatments, and this gap is overcome with clinical judgment and with firm devotion to patient centeredness. 

"Medicine has imperceptibly led us into the social field and placed us in a position of confronting directly the great problems of our time." - Rudolf Virchow 1848

He also believes that much of disease prevalence and outcome is socially and environmentally determined.  So, a physician's responsibility does not end with compassionate and effective medical care at the bedside; that is just the beginning.  Physicians need to understand the social and structural forces that influence health and disease outcomes, so they can use their intellectual and political power for a healthier population and avoidable disparity. 

He started working at CHA in 2009 as a teaching hospitalist and joined the residency leadership team in 2011 as the Associate Program director of inpatient training.  His areas of interest are clinical reasoning, bedside teaching, point of care ultrasound, evidence based medicine, and global health.

Jess Hoy is not a night owl. However, she loves clinical medicine and has somehow found herself to be a very happy nocturnist.

Trained at Harvard Medical School and Brigham and Women's Primary Care residency, Jess worked for a few years after residency on Navajo Nation at the Indian Health Service. She admired the grit, teamwork and clinical acumen of the clinicians there, and loved practicing 360 degrees of internal medicine - from the primary care clinic to the intensive care unit.

After returning to Boston, she became a nocturnist at CHA at the beginning of the pandemic. She has found that working at night is a privileged position - it affords time to spend with patients and to deepdive into the medical and social factors that led to this moment; it presents endlessly interesting and undifferentiated clinical cases; and it allows her to support patients in the deeply uncertain moments surrounding acute illness at the time of hospitalization. Aligned with her focus on improving patient care, she is a member of the Morbidity and Mortality committee.

In the residency, she is the Director of Evaluation where she hopes to foster compassionate, growth oriented and fortifying feedback for residents. She believes that CHA faculty is uniquely situated to know each resident well both professionally and personally, and that this is the strongest basis for resident growth. She is also the Director of the Night Curriculum where she hopes to make night shifts valuable and sustainable for residents.

She is a mother to two dynamic kids and a very sweet dog. She is an avid ceramics potter, an eager reader of poetry and fiction and an explorer of the lively city of Cambridge.

Dr. Amy Pasternack grew up across the river in Brookline. Her father is a pediatric infectious disease specialist who also kept his adult medicine primary care panel ever since residency, so she spent her childhood hearing all about germs and long-term patient-doctor relationships. She studied molecular and cellular biology and Spanish in college and helped lead a student-run homeless shelter during that time. While applying to medical school, she worked as an intern for the Valley Homeless Healthcare Program, part of the safety net hospital system in Santa Clara County, CA, where she did some quality improvement work on skin and soft tissue infections, hepatitis C treatment, and care of migrant farmworkers. She first experienced CHA as a second year Harvard medical student, when she did her physical diagnosis course at CHA and got to learn from outstanding faculty and patients. After doing her clinical year at a tertiary hospital, she was excited by the opportunity to put down deeper roots at CHA by choosing a training program that would focus on her interests in community primary care and underserved patient populations. Her intern year was the first year of the Windsor clinic's current incarnation as an internal medicine residency teaching site; she was delighted to keep her Windsor patient panel as she transitioned from residency through a chief residency year to being an attending. She is now the site director for the residents at the Windsor clinic and loves learning alongside the residents and helping trainees build their clinical reasoning skills. She went into primary care to build meaningful long term connections with patients and to accompany them through their ups and downs, and this process has begun to take shape over the years. In addition, she has been so fortunate to work with incredible colleagues on the Windsor team who take such good care of her. She lives in Somerville with her partner (a mathematician), her two kids (avid baseball fans), and her container garden (with the best heirloom cucumbers).

"Without a doubt this has been one of the most professionally rewarding jobs I've ever held. The staff is outstanding in both their level of expertise and their commitment to patient care and academics. The community is supportive and diverse. And the program for medical education seems to have found that delicate balance between high expectations and humane treatment."

Michael Payne was born and raised in Chicago. He earned BA, MD, and MPH degrees from Harvard and completed both an internal medicine residency and a gastroenterology fellowship in Boston.

In addition to patient care and resident education, Dr. Phillips taught medical students in the CIC program, trained in the treatment of hepatitis C in the primary care setting, and has interests in quality improvement. She participated in the CHA-Gold Innovation Fellowship in 2019 and is the former Medical Director of the Mobile Integrative Health program which provided urgent medical care to homebound patients in the community.

Dr. Galina Tan currently practices as a primary care physician at CHA and is involved in medical education as the residency program's Director of Ambulatory EMR Education and also as an Instructor of Medicine at Harvard Medical School. She is a proud graduate of the CHA Internal Medicine residency program class of 2016. She stayed on as chief resident, and chose to continue her practice at CHA because of the mission, community and teaching opportunities.

As a medical student at New York University School of Medicine, Dr. Tan was actively involved in the student-run free clinic and was co-chair the Women's Health free clinic. This opened her eyes up to the harsh reality of how the US healthcare system often fails patients, as well as the value of preventative care. She wanted to train and work in a place that understands this and seeks to innovate ways to address these gaps in healthcare.

She feels incredibly fortunate to have been able to start her career at a place like CHA. Training here and being surrounded by like-minded colleagues who value primary care and social justice has been a way she has been able to sustain joy and hope in her practice. As a generalist, she has a wide variety of clinical interests including harm reduction approaches with opioids in chronic pain management, substance use disorder, and LGBTQIA+ health. She also takes pride in fostering community and advocacy by helping to create the Social Justice Coalition at CHA, as well as her involvement with the Health and Public Policy Committee of the MA chapter of the American College of Physicians (ACP).
