Dr. Hassler has been practicing medicine since the year 2000. She enjoys seeing a variety of patients and getting to know each patient and their family individually. “I do my best to listen to each patient or parent and to understand and address their questions and concerns.” Dr. Hassler feels that while technology has made practice more efficient, it can also make it less personal, so she works hard to combat that. In her free time, Dr. Hassler likes to spend time with her family both at home and on the Cape.
