ADHD therapists and psychiatrists in Rancho Cucamonga, CA

I work with adults who want to better understand themselves, strengthen emotional resilience, and create meaningful, lasting change. My style is warm, collaborative, and empowering — I believe you are the expert on your own life.

As a graduate of the University of Southern California, my training emphasized both clinical excellence and authentic human connection. I integrate CBT and DBT-informed approaches to help clients develop practical skills for managing emotions, navigating relationships, setting healthy boundaries, and shifting unhelpful thought patterns.

I was drawn to this work because I’ve seen how powerful self-awareness and skill-building can be in transforming not only how we cope, but how we experience ourselves and our relationships. I understand that seeking therapy can feel vulnerable, and I strive to create a grounded, supportive space where you feel truly seen — while also gently challenged to grow in ways that build confidence, clarity, and lasting self-trust.

Hi, I'm Dr. Umugbe — and I'm here to help you make sense of what you're going through.

I'm a board-certified General, Child, and Adolescent Psychiatrist with over 20 years of experience helping children, teens, and adults navigate some of the most challenging mental health conditions out there — psychotic disorders, ADHD, depression, bipolar disorder, anxiety, and more. I see patients via telehealth and also offer in-person visits in Rancho Cucamonga, CA.

Two decades in this field has taught me one thing above everything else: the best care starts with truly knowing the person in front of you. Not just their diagnosis — their story, their symptoms, how long they've been carrying this, and how it's affecting their daily life. That's always where I begin.

I've worked for 8 years helping people get in touch with what they want. I've primarily worked with individuals navigating difficult life and interpersonal transitions, supporting professionals who are navigating career changes, and folks embarking on post-graduate educational pursuits.

I have been practicing medicine as a nurse practitioner for 23 years, and psychiatry has always been my passion. My work is driven by caring, empathy, and a genuine love for people. When I meet someone for the first time, I pay close attention to the sadness, anxiety, pain, or confusion they may be experiencing. I listen carefully and begin thinking about how to help them move toward feeling balanced, healthy, and capable in their daily life.

My clinical focus includes mood disorders, attention difficulties, obsessive or intrusive thoughts, sleep issues, anger management, and psychosis. Over the years, I’ve developed a unique approach to medication management—one that combines experience, thoughtful evaluation, and individualized care to give each person the best chance at success.

I bring a wealth of experience from my work in child welfare for nearly 10 years, which has shaped me into a deeply trauma-informed practitioner. Over the years, I have supported clients of all ages and walks of life, including individuals facing complex socioeconomic stressors and diverse life circumstances. I am comfortable working with a wide range of mental health concerns, from mood disorders like anxiety and depression to more complex personality-based struggles. No matter your background or the challenge you are facing, I offer a stable, professional, and non-judgmental presence designed to help you process your experiences and move toward a healthier future.

I believe that therapy is a partnership, and my goal is to provide a safe, non-judgmental space where you feel truly heard.

I am dedicated to working alongside you to build on your existing strengths, foster resilience, and help you create the change you are seeking. You don’t have to navigate these challenges alone; I invite you to reach out so we can start this work together.
