Tom Geist is dedicated to helping individuals across Maine find purpose and meaning in their lives through evidence-based therapeutic techniques. He specializes in individual therapy for adults and seniors, working with a wide range of mental health challenges including anxiety, depression, psychosis, schizophrenia, and ADHD. By taking the time to deeply understand his clients’ histories and experiences, Tom helps guide them toward long-term emotional well-being. Serving patients across Maine, he emphasizes the use of Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Dialectical Behavior Therapy (DBT) to help his clients build healthier relationships with their thoughts and emotions. Tom is particularly passionate about supporting men, military veterans, and first responders as they navigate life transitions, midlife challenges, and mental health conditions such as sleep disorders and bipolar disorder. He takes an integrative approach that not only addresses immediate symptoms but also fosters a deeper exploration of life’s meaning and personal growth. In addition to his work with these populations, he offers tailored therapeutic interventions for those experiencing developmental disabilities and individuals recovering from head injuries, helping them build resilience and achieve their goals. In addition to his clinical focus, Tom is experienced in CBT for insomnia, helping clients improve their sleep and overall quality of life. His work extends beyond immediate treatment, as he believes in helping clients develop the skills they need for long-term emotional stability. Whether assisting someone in overcoming a psychological barrier or helping a client through midlife transitions, Tom is dedicated to making therapy a space of growth and empowerment. Outside of his work, Tom enjoys expressing his creativity through making music. He also finds peace in spending time outdoors, whether hiking or simply enjoying nature. Movie nights and quality time with his cats bring balance to his life, allowing him to recharge and bring his best self to his clinical practice. Serving individuals throughout Maine, Tom remains committed to helping his clients achieve meaningful change and personal fulfillment.
