What was your path to becoming a clinical psychologist?

I've always been a lifelong learner, and been interested in helping others achieve their learning goals. As a psychology major in college, I was also a director of a theater program at a local high school. It was then that I became interested in helping school-age children develop their unique skills and talents. Pursuing a graduate degree in School Psychology, I discovered that I was interested in working with individuals of all ages in both psychological assessment, learning interventions, and therapeutic interventions.

What would you say to someone who is very anxious about learning problems in school?

Every person can make a valuable contribution to this world. If the world was only made up of the contributions of neurotypical individuals, it would be a pretty dull place. School failures are not moral failures, but sometimes are just a result of trying to fit a round peg into a square hole. Working with a compassionate care team can help you overcome the anxiety that comes along with school failures. Your hard work will pay off!

What advice would you give to a family who is on the fence about signing up for a learning assessment?

A targeted learning assessment can pave the way for developing effective intervention and accommodations plans. Without a learning assessment, educators may be blindly picking interventions that are not tailored to an individual's strengths and weaknesses. Moreover, for children or adults with any kind of learning or psychological disability, there may be relevant legal protections under IDEA, Section 504 of the Rehab Act of 1973, or the Americans with Disabilities Act that promote learning or offer reasonable accommodations to persons with disabilities. Without an appropriate documentation of disability or learning needs, individuals may not be able to access the supports and accommodations they need.
