About Family Health Center: Diversity of staff, patients, cultures, illnesses at a health center with a wide variety of services. Commitment to high quality care linked with training programs (MDs, NPs, social workers, dental residents) all in a setting dedicated to the underserved. Academic faculty with ongoing research interests relevant to our population (conveying prevention to low literacy patients; health care for homeless families; breast feeding practices among low income women; Centering Pregnancy, and many others.) Faculty with strongly evidence-based approaches and broad reading interests, always questioning, many of whom have practiced for years at the health center and have deep understanding of relationships with patients. Integration into medical care of mental health services, nutrition and health education services for multi-lingual populations. Residents graduate with diverse competencies and skills to go on learning—and many continue in health centers elsewhere.
Why Family Medicine? It was 1972. I knew I wanted to take care of women; within 2 months into my rotating internship I knew I wanted to take care of infants and children, too. Then I found out I liked working with adults, helping untangle the confusing symptoms from mind and body. I read Michael Balint and learned that the doctor plays a role in how the patient’s illness gets constructed. The only people who were talking about all this, who could link it all together, who saw that family relationships were central to health and sickness, who were critical of medical care as it was then—-were the people starting family practice residencies. I signed on as one of the first residents in this program. I was not disappointed!
Personal Facts: I live on 10 acres on a pond within the Worcester city limits and sometimes bike to work on a recumbent bike. I am working on a book possibly titled “It Runs in the Family” about diabetes and depression in my family of origin.

About Family Health Center: I have been practicing at the Family Health Center of Worcester (Queen Street) for 20 years and was the medical director for ten of those years. The health center serves a very diverse population, racially, ethnically and socioeconomically. I love practicing and teaching at the health center because I learn something new every day. The faculty are superb clinicians and teachers who are committed to caring for the underserved and training the future family physicians for community health centers and other underserved sites.
Why Family Medicine? I knew I would become a family physician by the middle of my first year of medical school despite the fact that only 6 of my 150 student class went into this specialty. I fell in love with the concept of whole person and family oriented care. Unquestionably, family physicians are best prepared to integrate management of medical and behavioral health issues.
Personal Facts: I enjoy gardening, hiking in the woods and good spy novels.

Massachusetts Institute of Technology, S.B. Computer Science
University of Massachusetts, M.D., 1999
Residency: UMass/Barre, 2002
Areas of Interest and Research: Integrative Medicine, Women's Health, Procedures, Teaching
Why Family Medicine? I started my career as a software engineer and worked part time as an EMT and then a paramedic as a hobby. Over the years I found that I enjoyed the medical aspects of my life more than the engineering, and so I decided to take the plunge and go to medical school. Then, after practicing Family Medicine for a few years, I realized that Western medicine had little to offer many patients. I started looking into non-Western therapies and have become an Integrative Medicine Practitioner. I am currently a board-certified medical acupuncturist and am trained in basic osteopathic manipulation, clinical hypnosis and functional medicine. I am always adding new tools to my kit, so there may be more by the time you read this! I also love doing and teaching various dermatologic and gynecologic procedures.

Personal Facts:  Before moving to Worcester I hadn’t stayed in one place longer than one year for 12 years. I love learning languages, and hope to continue to do so.

Sara G. Shields, MD, MS
Associate Professor
Harvard University, A.B., 1984
University of California at San Francisco, M.D., 1989
Residency: University of Rochester, 1992
Maternal & Child Health Fellowship, Memorial Hospital of Rhode Island, 1994
Areas of Interest and Research: Maternity Care, Underserved Populations, Women's Health. Co-author (with Lucy Candib, MD) of Woman-Centered Care in Pregnancy and Childbirth (Radcliffe, 2010.) I'm especially interested in breastfeeding and group prenatal care and how to teach residents to do groups.
About Family Health Center: When I'm able to be with residents attending one of their own patients' deliveries, I love encouraging the residents to discover and savor their unique longitudinal connections with laboring women and their families. This continuity during maternity care is what makes our role as family physicians so special and so important. Here at Family Health, we have such an incredible opportunity to serve a truly multicultural perinatal population with support systems that provide something unique and special to families otherwise so disempowered and disenfranchised in our society.
Personal Facts: My family loves pursuing New England's multi-season activities with kids (hiking, biking, camping, anything at Cape Cod, skiing and snowshoeing); in my nanoseconds of free time I enjoy reading novels, writing, knitting and sometimes coaching kids' soccer or teaching Sunday School.



Olga Valdman, MD
Director of the Global Health Track
UMass Medical School
Residency:  Lawrence Family Medicine Residency
Areas of Interest and Research: International Medicine, Maternal Child Health
About Family Health Center: I chose to come back to UMass after completing my residency because I missed the supportive and nurturing community that it is. Additionally, I truly missed Worcester as one of the most diverse (culturally, economically and racially) city I have ever lived in. Unlike New York and Boston where I had lived before, Worcester has the most sense of a mixed community which truly comes to life when you walk into the Family Health Center where I chose to come to. I walk into the building in the morning, look around and feel incredibly lucky to be surrounded by people from all over the world, hearing numerous languages spoken at the same time and being welcomed by our staff always ready to teach me about their community.
Personal Facts: Originally from Russia, I moved to the US at the age of 15. Being an immigrant myself, I have grown a deep interest and passion for working with immigrant and refugee populations, particularly in the underserved communities. While in medical school and residency, I was lucky to travel to several countries while learning about the local medical system and providing clinical services. In particular, I have travelled to Dominican Republic, Nicaragua, Ghana, Ethiopia and Mexico. Back in Worcester, I co-founded an African Community Education program which works with children who are refugees from various African countries providing them with remedial education and psychosocial support; working with the African community in Worcester has been an amazing journey for me. In medicine, my biggest interests are Global Health and Maternal Child Health.
