About Us

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 psychology practice located in Boulder, CO, where 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 therapist in the Child, Adolescent and Family Services program.

I have also enjoyed teaching throughout my career. Currently, I serve as a Clinical Instructor in the Department of Psychology and Neuroscience at the University of Colorado Boulder, where I supervise graduate level psychology students on clinical cases through the Raimy Psychology Clinic. Prior to this, I served as the Director of Clinical and Scientific Engagement at the Raimy Clinic at the University of Colorado Boulder, as an adjunct professor at the University of Denver in the Graduate School of Professional Psychology, as a Clinical Instructor at Bellevue Hospital Center, New York University School of Medicine, Department of Psychiatry. In addition, I have supervised graduate students and post doctoral fellows training in a private practice context. Along with formal teaching and supervision, I have presented at a number of professional conferences and provided workshops and seminars on CBT and DBT to consumers and professionals.

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, life transitions, relationship functioning and daily stressors.

Sarah Tilzey, PhD

I am a doctoral level psychologist, licensed in the state of Colorado and currently providing services at Foothills CBT. I received my doctorate degree in Clinical Psychology with an emphasis in child and adolescent trauma from Palo Alto University. Prior to my graduate training, I earned a bachelor’s degree in Psychology from the University of Nevada, Reno. As part of my doctoral training, I completed a pre-doctoral Clinical Psychology internship at the Colorado State University (CSU) Health Network. I then continued my training at the CSU Health Network as a post-doctoral fellow, specializing in providing DBT-informed post-hospitalization care to college students.

I am continually inspired by my clients and feel strongly dedicated to using strengths-based approaches to foster resilience and help individuals reach their goals and build worthwhile lives. Furthermore, I strongly value the extensive training I received in evidenced-based treatments, including Dialectal Behavioral Therapy (DBT), Cognitive Behavioral Therapy (CBT), and Interpersonal Process Therapy (IPT), among other approaches. My training, work experience, and interests extend across the lifespan, and I greatly enjoy working with children, adolescents, young adults, and adults. My clinical experience includes a wide array of presenting concerns, including trauma, relational concerns, anxiety, depression, personality disorders, bipolar disorder, identity-based concerns, eating and body image concerns, obsessive-compulsive disorder, suicide, and self-harm behaviors.
