About Dr. Samantha Monk Grigsby

Dr. Samantha Monk Grigsby, PhD

I am a clinical psychologist licensed in New York and Colorado. I earned my Doctorate in Clinical and School Psychology from Hofstra University in New York. Prior to my doctoral training, I received a Masters degree, with distinction, in General Psychology from New York University and Bachelors degree in psychology from the University of Colorado, Boulder. As part of my doctoral training, I completed a pre-doctoral Clinical Psychology internship at the Veterans Affairs Hudson Valley Healthcare System and a pre-doctoral School Psychology Internship in the Great Neck, NY school district. After receiving my doctorate, I completed my postdoctoral fellowship in Cognitive Behavior Therapy and Dialectical Behavior Therapy at CBT/DBT Associates, a private practice group in New York City.  

Currently, I provide psychological services through my private practice located in Boulder, CO. In Boulder, I am an affiliate of the Boulder Center for Cognitive and Behavior Therapies. Prior to opening my practice in Colorado, I served as a Staff Psychologist and Director of the Treatment for Performance-Related Anxiety and Panic Disorder program at CBT/DBT Associates. As a clinician at CBT/DBT Associates, I served as an individual therapist in the CBT program, an individual therapist and skills group leader in CBT/DBT Associate’s Comprehensive Dialectical Behavior Therapy Program, as well as a child psychologist in the Child, Adolescent and Family Services program.

I have also enjoyed teaching throughout my career. Most recently, I served as the Director of Clinical and Scientific Engagement at the Raimy Clinic at the University of Colorado Boulder. In this position I oversaw and supervised the clinical training of the Clinical Psychology PhD students in the Department of Psychology and Neuroscience. Formerly, I served as an adjunct professor at the University of Denver in the Graduate School of Professional Psychology, teaching cognitive behavioral therapy to graduate students. Prior to this, I was a Clinical Instructor at Bellevue Hospital Center, New York University School of Medicine, Department of Psychiatry, where I provided cognitive behavioral therapy supervision to advanced psychiatry residents. In addition to academia, I have presented at a number of professional conferences and provided workshops and seminars on CBT and DBT to consumers and professionals. In addition, I have supervised graduate students and post doctoral fellows training in a private practice context. 

I have great passion for the therapies I provide. Throughout my career, I have sought extensive training and experience in evidence-based treatments, including Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT) and Acceptance and Commitment Therapy (ACT). I have had specialty training and experience working across the lifespan with adults, adolescents and children. My clinical expertise focuses on a wide range of problems, including anxiety, panic, worry, depression, test anxiety, sports performance anxiety, posttraumatic stress disorder, substance abuse, insomnia, relationship problems, and daily stressors.
