Addiction therapists & psychiatrists in Rancho Cucamonga, CA

Hello, my name is Alexander Valenzuela PMHNP. I specialize in psychiatric medication management and cognitive behavioral talk therapy. If you're struggling with your mental health and realize you want help, you don't have to do it alone. I am looking forward to starting the journey with you to help achieve your best self.

I'm Candice Jeffers, a board-certified Psychiatric Mental Health Nurse Practitioner with an unusual background—I spent nearly a decade in cardiovascular critical care before dedicating myself to mental health. That ICU experience taught me something crucial: psychiatric crises deserve the same urgency, expertise, and unwavering support as any cardiac emergency.

For nine years at Ascension Seton Medical Center's Cardiovascular ICU, I supervised teams through impossible situations. I learned to stay steady when everything felt uncertain, to read the subtle signs others might miss, and to offer hope when families needed it most. Those years shaped how I practice psychiatry today—with precision, presence, and profound respect for what you're facing.

I completed my Master of Science in Nursing at University of South Alabama in 2024, immersing myself in over 600 clinical hours spanning outpatient clinics, inpatient psychiatry, and crisis intervention. My pediatric nursing background adds another layer—I understand how early experiences shape us and how differently mental health shows up across ages.

My practice centers on thorough psychiatric evaluations, personalized medication management, and crisis intervention for all ages. I specialize in suicide risk assessment, trauma-informed approaches, and evidence-based treatments that actually fit into real lives. I'm MOUD-trained and licensed for telehealth in Texas, California, Arizona, and Florida.

Here's what matters most: I approach mental health as someone who's held space for both miracles and heartbreak. I know seeking help requires tremendous courage. I know healing rarely follows a straight line. And I know you need a provider who won't flinch, no matter what you share. My work blends critical care decisiveness with deep compassion—because you deserve both.

As a PMHNP-BC who specializes in autism, complex cases, OCD, personality disorders, PTSD/trauma, schizophrenia/psychosis disorders, and substance use, I've built my practice around understanding that every person's mental health journey is unique—especially when multiple conditions interact or when traditional approaches haven't worked.

I also provide comprehensive treatment for depression, anxiety, panic disorders, mood disorders, and bipolar disorder, always with an understanding that these conditions often overlap and influence each other in complex ways. What I want you to know is this: your experiences are valid, your struggles make sense in the context of your life, and there's no such thing as being "too much" for treatment.

Whether you're masking autistic traits, battling compulsive behaviors, managing intense emotions, processing trauma, questioning reality, or struggling with substances, I meet you exactly where you are without trying to force you into a predetermined mold. My approach combines evidence-based treatments with deep respect for your individual needs and experiences.

You deserve a provider who doesn't see complexity as a problem to solve, but as a roadmap to understanding how to best support your unique path to wellness.

I specialize in trauma informed treatment that includes PTSD, depression, anxiety and phobias.

Hi,

I’m Megan , an LMFT , licensed in California. I am an easy going , kind and compassionate psychotherapist who provides a safe and non-judgmental space for clients to process life’s challenges and grow in self awareness . I empower clients to find their peace and restore balance.

I have a Masters Degree in Clinical Social Work, and a Licensed Clinical Social Worker (LCSW), working in private practice as a Psychotherapist. I live in Los Angeles, and work in-person or hybrid, with adults, teens, couples and the aging population. I specialize in anxiety, life transitions, relationship issues, work stress/dissatisfaction, career goals, sleep disorders, substance use, trauma (ptsd/complex/acute), obsessive compulsive disorders (OCD/OCPD), attention deficit disorders (ADD/ADHD).

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.
