About Thomas

Thomas Grinnell is a Licensed Clinical Social Worker who helps people manage stress, anxiety, depression, trauma, grief, bipolar disorder, addictions, relationship and intimacy concerns, and parenting challenges. He practices from New York and draws on 12 years of direct counseling experience to offer clear, practical support. He uses a person-centered style that keeps the client's priorities first.

Sessions focus on what matters now and on small, doable steps. Thomas blends talk therapy with skills practice so people leave with tools they can use between sessions.

Background and approach

Cognitive Behavioral Therapy is often part of his work. That means identifying unhelpful thinking patterns and testing new behaviors to reduce symptoms. Dialectical Behavior Therapy skills are used when emotional regulation and distress tolerance are main issues.

Thomas also brings motivational interviewing to conversations about change. That approach helps people clarify goals and resolve mixed feelings about making shifts. Mindfulness techniques are woven in to build awareness and reduce reactivity.

He has experience supporting people with a broad range of diagnoses and life challenges, including intellectual disability, mood and personality disorders, obsessive-compulsive concerns, and post-traumatic stress. Sessions are aimed at practical coping, clearer decision-making, and improving day-to-day functioning. People who choose Thomas can expect a straightforward, compassionate style that emphasizes collaboration and measurable steps.

He invites prospective clients to discuss concerns, try strategies, and refine the plan as needed.

Online support

How therapeutic approaches translate to online care

Thomas often integrates Cognitive Behavioral Therapy and Dialectical Behavior Therapy into online work. CBT focuses on spotting unhelpful thoughts and trying different behaviors to reduce symptoms, which fits well into video or phone sessions where homework and behavioral experiments are assigned. DBT supplies concrete skills for emotion regulation and distress tolerance that can be taught, practiced, and reviewed during sessions and via messaging.

He also uses Client-Centered Therapy to keep sessions focused on the person's goals and preferences. Finding the right mix of approaches is a collaborative process - the therapist will work with the client to decide which methods match their needs, goals, and comfort with different formats.r>
Online sessions are offered as video calls, phone sessions, live chat, or text-based messaging to increase flexibility. Video is useful for in-depth work and skill coaching, phone can be easier when bandwidth is limited, chat supports brief check-ins and clarifications, and messaging lets clients send updates or practice between appointments. These options make it easier to fit therapy into busy schedules and to continue work between sessions.
