A native of the Berkshires, Sonya Merrill, MD, PhD, often attended concerts at the Shed at Tanglewood as a young child. This early exposure to classical music prompted her to start violin lessons at age three. After moving to Dallas, Sonya continued her studies with Melvin Baer of the Dallas Symphony Orchestra and later joined the Greater Dallas Youth Orchestra. She returned to her home state of Massachusetts to attend Wellesley College where she majored in philosophy and continued her musical interests. She also was fortunate to be able to play with a number of college orchestras while studying philosophy for five years in England, first as an undergraduate at the University of Cambridge and later as an MA and PhD student at the University of London.

She served for twelve years as the associate program director of the internal medicine residency program at Texas Health Presbyterian Hospital Dallas where she enjoyed mentoring young physicians."
