Mary Lannon-Developmental Therapist

I graduated from Ball State University in 2016 with a Bachelors Degree in Child Development.

I have experience working with all children from 1-5 and am excited to be a part of the early intervention process. I am also excited to work with PSA! In my spare time I love to travel and spend time with family and friends.
