ADHD therapists and psychiatrists in Simi Valley, CA

I am a board certified, doctoral prepared PMHNP. I completed my post graduate at National University in Adult, Child and Adolescent Psychiatry. I earned my DNP from Azusa Pacific University and graduated from CSUSB MSN program. I have been a faculty at CSUSB since 2014. Extensively trained and a certified Trauma-Informed specialist. I diagnose and treat mental disorders including medication-assisted treatment along with counseling for chemical dependency and substance use disorders.

I specialize in working with adults experiencing burnout, chronic stress/anxiety, trauma, and neurodivergence. As a neurodivergent therapist who has navigated my own experiences with burnout, I understand how exhausting it can be to constantly feel "on" for everyone else. I’m especially passionate about supporting helping professionals, caregivers, and high-achieving folks who spend so much energy caring for others that they forget to care for themselves. I also bring my full personality into the therapy room (including humor, authenticity, and the occasional slightly twisted joke) when the moment calls for it.

Hi, my name is Ning! I am a Licensed Professional Clinical Counselor. I hold a bachelor’s degree in Social and Behavioral Sciences and a master’s degree in Clinical Mental Health Counseling. For the past seven years, I have worked with children, teens, adults, and older adults facing stress, anxiety, relationship challenges, major life transitions, complex mental health conditions. My clinical work focuses on anxiety and mood disorders, and I combine cognitive and somatic techniques with talk therapy to address root causes and foster lasting personal growth.

I’m Thomas Moore, LPCC, a licensed professional clinical counselor providing therapy for individuals navigating anxiety, trauma, emotional overwhelm, identity development, and complex relational patterns. Many of the people I work with feel stuck in repeating cycles such as overthinking, people pleasing, emotional shutdown, intense reactions, or difficulty maintaining stable relationships even when they logically understand what they should do. My goal is to help you translate insight into real change.

My approach is structured and compassionate. I integrate evidence based methods including cognitive restructuring, emotional regulation training, interpersonal effectiveness skills, and trauma informed therapy. Sessions focus on understanding why your brain reacts the way it does and building practical tools you can actually use outside the therapy room. This is not only about talking through problems but learning how to respond differently when they show up in real life.

I work well with clients who want more than passive support and are ready to build skills, increase self awareness, and interrupt patterns that no longer serve them.

What clients should know before starting

Therapy with me is collaborative and active and you will learn strategies rather than only venting. We will work on understanding both the emotional and neurological side of your reactions. Sessions focus on present day functioning while also addressing past experiences that still affect you. I may gently challenge patterns when it supports growth while maintaining a supportive and respectful space. Progress often comes from small repeated changes rather than sudden breakthroughs.

If you are looking for therapy that combines validation with practical change, we will likely work well together.

I'm Roz Hedayatian, a Licensed Marriage and Family Therapist in Los Angeles. I work with adults who are navigating relational pain, anxiety, and life transitions.
