Dr Chang is a very skilled physician. She has great people skills and recently used them to get me through a procedure that I was scared to death of having done but needed to completed. She not only took time to understand why I was so afraid but helped me through my emotions to complete the procedure.

Dr. Mona P. Chang, M.D. is a board-certified family physician who has been working at Cornerstone since 1989. She resigned from delivering babies after 14 years and now serves patients of all ages, from newborn to nursing home at the River Avenue, Williamsport (Cornerstone) location of Family Practice Center.
Dr. Chang feels that family practice medicine is a good way to tie an interest in science with a desire to be useful to the greatest variety of people. She tries to allow her patients to make many of their own decisions, particularly in preventive care and early detection, being more of a health care consultant than a dictator. Her favorite quote for her patients: Take care of your body as if you `re going to live forever and your soul as if you`re going to die tomorrow.
Dr. Chang was born in New Jersey and is married to teacher, writer and speaker, Joseph W. Smith, III. They have two sons: Douglas, who is a civil engineer in Fairfax, Virginia, and Timothy who has his MFA in Creative Writing from the University of North Carolina – Wilmington.
In her free time, Dr. Chang serves at the New Life Orthodox Presbyterian Church coordinating the Sunday School program and organizing the annual Spring Cleaning Giveaway.
