In 1992 Doreen was inspired to leave her full-time professional position as Paralegal to Attorney Robert M. Schwartz, to set out and teach yoga throughout Boston. Doreen has taught at Boston and Brookline Adult Education, for Fitcorps (Hale and Dorr), for Healthworks Cambridge, Brookline and Boston, at Mount Auburn Club in Watertown. She brought Yoga into the Boston Racquet Club and taught in various corporations including the financial institution Charles Schwab, and The United Way. She taught at Babson College in Wellesley for six years and was adjunct faculty at Northeastern University for twelve years. She has taught specialized topics in yoga for Occupational Therapists at Tufts University in Medford. Long before Massage and Yoga for Pregnancy became their own specialities, Doreen was detailing her practices to meet the special needs of pregnant students and clients. Understanding yoga and massage's clinical implications in health and wellness, Doreen's yoga classes and body therapies included programs and treatments for building the immune system and strengthening the mind and the body. Doreen was among the first massage therapists in Boston to become Nationally Certified as well as among the first massage therapists in Boston to hold statewide licensure. In the early 1990's, on faith and inspiration and at the request of several students, Doreen designed and taught a yoga teacher program that progressed to a two hundred hour program including studies, practices, student teaching and mentoring. Doreen trained over thirty students.
