Samantha Monk Grigsby, PhD
Clinical Director
Dr. Samantha Monk Grigsby is the founder and Clinical Director of Foothills CBT Psychology Group, a doctoral-level group psychology practice in Boulder, Colorado. She founded the practice in 2013 and expanded it into a group model in 2021, building a team of psychologists who share a commitment to clinical excellence and evidence-based care. As Clinical Director, Dr. Grigsby oversees the clinical quality of the practice’s work, supervises its postdoctoral fellows, and consults regularly with each member of the team on their clinical cases. She leads the practice guided by a commitment to three communities she holds central to its mission: the clients who entrust the practice with their care, the clinicians whose expertise and well-being sustain that care, and the broader Boulder community the practice is proud to serve.
In addition to leading the practice, Dr. Grigsby maintains a limited clinical caseload, bringing deep expertise and genuine passion to her work with clients. Throughout her career, she has pursued extensive training in evidence-based treatments, including Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Acceptance and Commitment Therapy (ACT), and she has specialty training in working across the lifespan with adults, adolescents, and children. Her clinical expertise spans a wide range of concerns, including anxiety, panic, worry, depression, social anxiety, test anxiety, life transitions, relationship functioning, and daily stressors. Dr. Grigsby is not currently accepting new clients; prospective clients are warmly invited to connect with one of the practice’s psychologists, each of whom she has carefully selected and continues to support through ongoing consultation.
