Physical Therapy

Sandra Heberlig, PT

Hi, my name is Sandra Heberlig but the kids call me Mrs. H. I have had the privilege of working at the Mary Finn School for 6 years. I am employed by Assabet Valley Collaborative. My passion for working with kids came after my son was born premature and spent years receiving Early Intervention. I graduated with my bachelors degree from the School of Physical Therapy at McGill University. In addition to the Mary Finn School, I also service students across the district in 5 other schools. I have worked in a variety of medical settings across my career which include outpatient clinics in orthopedics, neurology, and pain management, acute care settings, and rehabilitation hospitals.

In my free time, I love traveling with my husband and 2 middle school children. I enjoy a challenging workout and hiking in unique places.

Hi, my name is Andrea Flanagan. This is my 13th school year working at Mary Finn as well as all of the schools throughout the Northborough-Southborough school district. I am employed by Assabet Valley Collaborative for the past 16 years. I am a 1998 graduate of American International College with a Bachelor of Science degree and a 2000 graduate from Springfield Technical Community College as a Physical Therapy Assistant.

I live with my husband, daughter and son. My interests include reading, spending time with my family, going to the beach and yoga. I teach children’s yoga on the weekends at a local studio where I take classes myself!
