About Hahnemann: I joined the HFHC team when I graduated residency because I found my professional home with the HFHC faculty. I was searching for a practice where I could see myself long term to develop lifelong relationships with my patients, where I could continue to practice full spectrum maternity care, and where I could grow as a physician and as an educator. I found a shared mission for education, continuous improvement, and high quality primary care with the HFHC group and am excited to call HFHC home.

Why Family Medicine? I cherish the privilege to care for families and help others improve their health. In family medicine I found a shared passion for preventative care, maternal child health, and the impact long term relationships can have on patients health. I value being able to care for my patients with most of the health issues they will face and to be a partner with them for issues that require care for others. Family medicine is a specialty that allows for flexibility, growth, innovation, and evolution and it was simply the perfect fit for me.



Henry Del Rosario, MD
Assistant Professor

Biography: Dr. Del Rosario is an Assistant Professor of Family Medicine and Community Health at Hahnemann Family Health Center.

Dr. Del Rosario’s interests include global health. He has made several trips to northern and southern China helping to teach family medicine to residents as well as establish a culture of primary care in Asia. He has a passion for medical education and the theory of teaching so he is excited to be part of the culture of learning at Hahnemann. Dr. Del Rosario also enjoys procedures and teaching procedures (toenail removals!). He has a heart for racial minorities and refugee health care. 

He lives in Providence, RI with his wife, Jisoo, a pulmonologist at Brown. When he is not commuting, he enjoys hiking and art (particularly Zen calligraphy and photography). Artist portfolio can be found online at www.henrydelrosario.com/ 

Why Family Medicine? The beauty of family medicine comes from seeing patients from birth to death, in the clinic and in the hospital, and multiple members of the same family. As a doctor you are privy to some of the most intimate, vulnerable, and beautiful aspects of human experience. I find that this variety is mentally fulfilling, fun, and sustainable. A wide spectrum may also bring in difficult situations or patients very different than you, but uncomfortableness stretches your heart muscle— and empathy is something we need more of in this world. 




Michael Ennis, MD

Williams College, 1979
University of Rochester School of Medicine and Dentistry, 1983
Family Medicine Residency, UMass Medical School, 1986
Areas of Interest and Research: Student/Resident Mentoring, Family Centered Maternity Care, Travel Medicine
Hometown: The Bronx, NY
About Hahnemann: Teaching residents and students feels like a special privilege that I get to enjoy every day. It is definitely one of the top reasons that I have continued to work at Hahnemann for 23+ years. Bearing witness to, and occasionally helping, our residents transform into highly competent clinicians is a blast!
Why Family Medicine? My reasons for choosing family medicine continue to constantly morph and evolve. Perhaps, as a student, I initially came to this work enchanted by the idea of caring for the broadest of spectrums: “the cradle to the grave.” Nowadays, it is much more the continuity that I have with my families that sustains my passion for being a family doctor. Caring for extended families, sometimes 4 generations, delivering the babies of women whom I delivered as babies....these things too feel like a unique privilege that family doctors get to enjoy.
Personal Facts: I worked as a taxidriver in NYC for several years prior to going to medical school.




David Gilchrist, MD, MBA
Assistant Professor of Family Medicine and Community Health
Medical Director, Hahnemann Family Health Center
President, Massachusetts Academy of Family Physicians

Biography: Dr. Gilchrist is an Assistant Professor of Family Medicine and Community Health and has been the Medical director at the Hahnemann Family Health Center since 2012. Dr. Gilchrist went to Gordon College for his undergraduate degree in chemistry and earned his medical degree at the University of Massachusetts Medical School.

Dr. Gilchrist lives in Holden, MA with his wife Cammie and they have four children. Outside of work, he is passionate about triathlons and enjoys competing in local races.

About Hahnemann: HFHC is where I have grown up as a doctor. From my first experiences here as a medical student in my first year, I could tell that HFHC was a place where everyone gets to learn each day. The faculty and staff are committed to helping our learners, and each other, grow. Whether you are part of chart rounds, a noon lecture, an idea board huddle with the whole office or working individually with a preceptor, you will grow as a learner at our health center. As the medical director, I am deeply committed to making the practice function well so all of the members of our team can thrive and our patients get excellent care.

Why Family Medicine? Family Medicine is all about the relationships that we get to develop with our patients. I love being part of a community where I get to know people and sometimes bump into them outside the office. Family doctors can play a huge role in helping individuals and families improve their health and well being. For me, one of those areas I really enjoy seeing transformation is in my patients who are struggling with addiction. These patients need someone in their corner to cheer them on in their recovery and help them overcome their own self doubt. I couldn’t ask for a more rewarding experience.




Gerald Gleich, MD

Interim Clinical Chief of Geriatrics, UMass Division of Geriatrics

About Hahnemann: I love my practice at Hahnemann. It is a well-organized, stimulating environment in which to practice, teach, and learn. I get to work with a terrific group of colleagues on the faculty who are committed educators and talented clinicians. I enjoy working closely with residents helping them grow and develop the skills and confidence they will need for their careers in Family Medicine. Worcester is the birth place of Family Medicine in Massachusetts and the UMass Family Medicine community continues to provide the leadership and support we need to help us train the family physicians of the future, and transform the way we deliver care to our patients.
Why Family Medicine? I initially chose to be a family physician because of my political belief that good health care is a right for all and it begins with primary care. Over the years family medicine has been an extremely fulfilling career for me. As I have changed and grown, I have been able to focus my career in different ways keeping me interested and engaged in my work. I enjoy talking to people, and learning about their lives, hearing their stories, and helping them make sense of, and come to terms with the ailments, stresses, discomforts, conflicts, and disabilities they face in their daily lives. I am a big picture person and also enjoy helping to make systems work better. I love being involved in medical education because I believe the physicians I help train today will carry on the traditions and philosophy of holistic patient centered-care that is central to family medicine.
Personal Facts: I play the guitar and sing and have written many songs over the years. Some of them are actually good. I enjoy downhill skiing in Vermont in the winter with my family, and cycling, golf, walking and playing basketball in the driveway with my youngest son (the one still at home) in the other seasons.




Jeremy Golding, MD
Clinical Professor of Family Medicine and Community Health
Family Medicine Quality Officer
Case Western Reserve University School of Medicine, MD, 1987

Family Medicine Residency (1990) and Fellowship (1991); Highland Hospital and University of Rochester
Areas of Interest and Research: Evidence-Based Medicine, Adolescent Medicine, Women's Health, Computers and Electronic Technology in Medicine, Electrocardiography, Dermatology, Office Surgical Procedures 

Biography: Dr. Golding is a Clinical Professor of Family Medicine and Community Health, and OB-GYN. After completing a fellowship in health services research in Rochester, he practiced family medicine, college health, and emergency medicine for about 10 years before coming to UMass. He was also a medical advisor of a Planned Parenthood site in CT. During his time as Inpatient Director for the department, he helped develop the family medicine hospitalist service. He still teaches EKG interpretation and ACLS for the residents on FMIS. Dr. Golding now divides his time among clinical, teaching, and administrative areas. He loves practicing the full spectrum of family medicine including obstetrics, but has a particular interest and expertise (certificate of added qualifications from the ABFM) in adolescent medicine. He enjoys seeing patients at Clark University and is the adolescent medicine consultant at the Worcester Recovery Center and Hospital. He is also associate editor of The 5 Minute Clinical Consult (Lippincott/Wolters Kluwer Health) (“I can’t believe I’m fortunate enough to get paid to write and edit and learn!”)

About Hahnemann: I joined the Hahnemann Family Health Center because I felt a particular kinship with the faculty there. We share a sense of mission to our patients and a passion for teaching our learners. In my clinical work, I co-run our procedure clinic, am an active colposcopist, and prescribe buprenorphine. I am continually reading and reviewing evidence-based medicine. Many of our residents have chosen to write with me, gaining valuable writing experience. All of our residents come with diverse interests and needs, and they are well-supported by an equally diverse, intelligent, amazing, and compassionate faculty committed to resident education. 

Why Family Medicine? I think I would get bored doing the same thing every day! Instead, I am constantly challenged by the innumerable presentations we see here in our office. I get to practice to the full extent of my knowledge, training, and experience. I have several multigenerational families in my practice, and find getting to know all my patients very satisfying. Over time, I have grown with the them. I cannot imagine practicing any other medical specialty. Although I will never be in the highest paid of physician specialties, I am already the most rewarded for my work.

Joy O'Brien, FNP-BC
Family Nurse Practitioner

I am originally from Texas but have spent almost half my life in Massachusetts. I came to healthcare as a second career after working in marketing and technology fields, and truly feel that I have found my calling making a small difference in the lives of my patients. I am grateful for the opportunity to work with multiple generations and to work with colleagues who have the same passion as I do. I am a lifelong learning and enjoy working with residents to get familiar with a team-based, collaborative practice, and I learn from the NP students that I precept. I also enjoy using medical technology to its fullest, data-mining and finding opportunities to improve care and delivery of care. I especially love caring for children and working with chronic health issues including addiction.

When not at work, my husband and I are building a cabin in Vermont most weekends in perpetuity. I love hiking with our two dogs whenever I get a chance and we go downhill skiing when weather permits.
