About Dr. Lesia Ruglass

Lesia M. Ruglass, Ph.D., Clinical PsychologistI am a Licensed Clinical Psychologist in NYC with over 15 years of experience providing psychotherapy and consultation to individuals, couples, and organizations. I am also an educator, researcher, and author with expertise in the assessment and treatment of relationship and work stress, loss, trauma, anxiety, and addictions.

My Style and Approach

My style is warm, engaging and collaborative.  I take an integrative approach to the therapeutic process, drawing from psychodynamic, cognitive-behavioral, and client-centered theories.  Click here to learn more about my treatment approaches and areas of specialization.

I strive to provide a safe, supportive and non-judgmental space where you can explore your current concerns and discover solutions that work for you. I will work with you  to determine the best therapeutic approach for your needs.


I received my B.A. in psychology from New York University, my M.A. in psychology from Boston University, and my Ph.D. in clinical psychology from the New School for Social Research in NYC.

During my years of doctoral training, I worked at several local area hospitals including Beth Israel Medical Center and Bellevue Hospital. I received specialized training in Psychodynamic Psychotherapy, Cognitive Behavioral Therapy and Dialectical Behavior Therapy.

I completed my clinical internship, postdoctoral fellowship, and worked as a Staff and Supervising Psychologist at the St. Luke’s-Roosevelt Hospital in NYC.  I also received extensive post-graduate training in executive coaching from the College of Executive Coaching and continue to be involved in their professional programs.
