Dr. Sam offers multiple therapy techniques to maximize healing:


Individual, Group, and Family Therapy

Is your talk therapy all talk?

Samantha Marks, Psy.D., aka Dr. Sam, knows that merely talking about change doesn’t mean it automatically happens.

Making improvements in one’s life takes time and energy both inside the therapy room and in the daily life. Learning concrete skills to implement outside of therapy is necessary to make progress.

Dr. Sam uses a pragmatic, goal-oriented approach to help clients effect real change. Therapy includes learning specific skills from DBT, (Dialectic Behavior Therapy), CBT (Cognitive Behavioral Therapy), ABA (Applied Behavior Analysis), or specific anxiety management/relaxation techniques that are applied to the clients’ daily lives with small, manageable goals. Practice makes Progress!

Dr. Sam is also uniquely qualified to work with the following:

  • Children, Adolescents, and Adults with Autism Spectrum Disorder or Social (Pragmatic) Communication Disorder
  • Tweens and Teens experiencing anxiety, depression, emotional dysregulation and/or problems with social skills/socialization
  • Clients transitioning to middle school or high school
  • Young adults having difficulty transitioning to college or the working world
  • Clients with ADHD (Attention Deficit Disorder) inattentive or combined types
  • Clients experiencing emotional dysregulation or fluctuating mood
  • Families with children with disruptive behaviors
  • Tweens and Teens in competitive sports, music performance, or with academic performance concerns

Visit Dr. Sam in her comfortable spacious office, browse titles in her library, or attend a group session or half-day seminar.
