Mary McGaughan, Psy.D.

about me.

I am a licensed psychologist working in Montclair, NJ. I work with t(w)eens age 12+, young adults, and adults. My therapeutic approach is guided by evidence based therapies that are tailored to each client’s unique needs.
I received my bachelor’s degree in psychology from Franklin & Marshall College and my Doctorate in School Psychology from St. John’s University. I completed my doctoral dissertation on the diagnosis of learning disabilities and subsequently completed pre and postdoctoral fellowships at the Albert Ellis Institute in New York City.
I have worked in a number of settings including psychological clinics, research facilities, public schools and private therapeutic school settings.
My specialized training is in Rational Emotive Behavior Therapy (REBT), a type of cognitive behavioral therapy (CBT). After completing a 2-year doctoral fellowship in REBT at the Albert Ellis Institute, I worked for several years as an institute staff therapist and became a certified REBT supervisor. I have also received training in Dialectical Behavior Therapy (DBT) techniques from Cognitive Behavioral Consultants in New York City and obtained supervision to modify DBT for use in school settings.

I love working with teens. They’re fun, interesting, and spunky. I learn new things from them and rely on them to keep me “in the know.” I like seeing them work hard to develop into independent, responsible, and happy adults.
Just as much, I enjoy understanding what has made people into the adults they have become and helping them become who they want to be.
I strongly believe that human beings are resilient and can always learn and adapt – no matter how old they are. Even when circumstances seem insurmountable, I believe people are capable of coping and managing in unbelievable ways.

Saying I’m “a dog person” is an understatement. Dogs are the best. I also like to run, garden, and sit in the sun mindlessly for hours. I DO NOT like to cook but I do love ordering out. My favorite restaurant? Ani Ramen.

why am i different?

I am trained in providing evidence based psychotherapies.

This means that there has been a lot of research supporting the approaches I use to help people feel better and function better.

I am a trained school psychologist.

I understand how emotions, peer relationships, academic and cognitive skills, biology, and genetics interact within a person’s culture, community, school, peer group, and family to make them who they are.

I am committed to collaboration.

I am ready and willing to collaborate with kids, parents, schools, and other providers to make sure everyone is on the same page so change can come about effectively and efficiently.

what do i do?

Most of my work is guided by principles of Cognitive Behavioral Therapy (CBT) and – more specifically – Rational Emotive Behavior Therapy (REBT). These are just fancy terms for saying I help people look at how their thoughts, feelings, and  behaviors impact how they feel. I help people figure out if their thoughts and actions are helping them feel better or worse. I then help them learn to think and act differently so they can feel better and achieve their goals. My work is also guided by principles of Dialectical Behavior Therapy (DBT). This is another type of therapy that is especially helpful for people who feel things really strongly, act somewhat intensely, and have difficulties calming down.
I provide therapy in person and via telehealth. To provide services, I need to be licensed in the state the CLIENT is located.
I am licensed in the following states: New Jersey – License #35SI00565000 New York – License #020555
PSYPACT (for telehealth) – APIT #13684
