ADHD therapists and psychiatrists in Castle Rock, CO

Hi! I am Leslie Choi, a Dual-Board Certified Pediatric and Psychiatric Nurse Practitioner. I have been providing psychiatric treatment to individuals across the lifespan as Faculty in the Department of Psychiatry at the University of Colorado since 2020. I expanded my work over the last 2 years to serve in the high school setting as an educator and resource for substance use prevention and intervention, and mental health promotion for young people. I have been a nurse for 26 years, with a wide variety of experience including as a Navy nurse, an oncology nurse, inpatient and outpatient pediatric nurse.

I treat individuals with a variety of mental health concerns, and specialize in treating adolescents and First Responders.

We'll meet at your readiness level and make meaning of the tough choices, navigate the hard edges, or forge a path through uncharted territory. I am a psychotherapist living in Colorado. I earned my MSW from Fordham University and have enjoyed previous work as a crisis therapist in hospital settings.

I began my career as a Fulbright Scholar, conducting research on traditional medicine in Sochi, Russia. I presented my work at the United States Embassy in Moscow, highlighting cross-cultural perspectives in healthcare and integrative practice.

After completing my grant, I attended New York University (NYU). I then completed a residency at M.D. Anderson Hospital in Houston, Texas. I went on to earn my doctorate from the University of San Diego, California, where I focused on digital telehealth treatment for psychiatric care.

I am passionate about working with Veterans and individuals experiencing Depression, Anxiety, and Mood Disorders. In 2023, I completed CIIS training in psychedelic-assisted therapy. In 2025, I was among the first providers in Colorado and in the country to become licensed as a psilocybin facilitator.

My primary focus is the restoration of the nervous system. I specialize in supporting recovery from complex, relational, and medical trauma. Because trauma impacts every layer of how we function, my practice also centers on the deeply connected challenges that come with it—including severe anxiety, chronic stress, mood fluctuations, complex personality patterns, and the profound journey of grief and loss.

My name is Summyji Groom and I am a Board Certified Psychiatric Mental Health Nurse Practitioner with over 17 years of experience in healthcare. My areas of expertise include depression and anxiety. I like to take a holistic approach utilizing diet, exercise, psychotherapy, and psychopharmacology. In my spare time, I enjoy spending time with family and traveling.

Therapy should be accessible and affordable, you deserve to life a live free of self judgment and doubt. I offer a warm, affirming, and nonjudgmental space where you can explore all parts of yourself. My approach is collaborative, helping you to find skills and ways of thinking that actually make a difference. My role is to walk alongside you as you slow things down, make sense of what’s happening inside, and reconnect with your own clarity and voice.
