Find therapists in Diamond Bar

Gregory Gooden

I enjoy working with clients who are faced with life changes, mal-adaptive coping mechanisms, struggles with personal identity, and relationship and sexuality issues.

Alexandria Guerrero

I work with individuals whose brains never clock out and whose hearts carry more than they let on. If you find yourself lying awake at night replaying every interaction you’ve ever had (including that awkward thing you said in 2016)—or feeling everything all at once like it’s your full-time job—you’re not alone. Therapy can help you slow down, sort things out, and finally exhale.

Jonathan Artigue

Jonathan specializes in supporting neurodivergent individuals navigating life transitions, addiction recovery, and mental health challenges. His integrative approach combines evidence-based therapies (CBT, DBT, and ACT) with mindfulness and solution-focused techniques. He creates a compassionate, structured environment where clients with ADHD, autism, anxiety, and depression can explore their unique experiences and develop personalized coping strategies.

Dr Don Etkes

I help people to cope with depression, anxiety, sexual issues, marriage challenges, gender issues, addictions, grief, ADD, relationships, sex addiction and family issues. I've helped celebrities, business leaders and the general public to move forward with their lives

Magena Ammen

If you've made it here, you’re ready to work through the trauma. You'd like to find a way to make life less painful. And, what if life could be gentler and more stable? What if you didn’t have to feel on edge or down and out?

Hope Flores

I specialize in working with individuals who identify as quirky, creative, LGBTQIA+, or those who simply don’t fit into conventional boxes. Whether you're exploring your identity, life transitions, or struggling with relationships and self-acceptance, I'm here to help you feel understood, validated, and supported. I approach therapy with an open mind and a dash of humor because growth doesn’t have to be all serious.

Nicole DeSimone

Clients seek me out when they want a supportive, high quality, low volume provider dedicated to client wellness. I provide Individual, Couples and Family Psychotherapy services to adults and adolescents. My clients are resilient, unique, and inspiring. My clients are motivated for change and are ready to actively participate in their own growth. Many of my clients are couples looking to improve communication and deepen their connection.

Annie Scully Blank

Do you often feel like anxiety is just beneath the surface, or find yourself struggling with overwhelming emotions out of nowhere? If you've experienced trauma, dealt with women's issues, or faced depression, these feelings can feel especially heavy. I understand how challenging it can be to carry these burdens. Therapy can help ease the impact of anxiety, depression, and trauma, and I’m here to guide you through the process of healing, explore tools to empower you, and create lasting change.

Heather Seguin

My clients are intelligent, insightful, caring, and generous people who feel turned upside down in their relationships. Some are in marriages that stopped working a long time ago and they want to make things better. Some have betrayed themselves and their loved ones with sexual behaviors that even they don't understand. And some are the partners of sex addicts, trying to figure out whether or not to work it out. My clients are amazing, compassionate people who want the best life they can have!

Lillian Strom

You may feel sad, empty, numb, angry, hopeless maybe. You've entered a time in your life when you feel so many different painful emotions all at once you can't identify exactly how you feel or where they are coming from. Maybe you can't sleep at night, or focus when you are awake. Your anxiety is higher than normal and your doing things you normally wouldn't. I can help you get your life back in order and work through the hurts that are troubling you. Tomorrow can be better.

Julianna Taillon

Are you struggling to cope with life transitions? Many of us are experiencing significant anxiety due to changing work environments, parenting children who aren’t in school or attempting to navigate the changing social conditions. Are you feeling stressed by a traumatic event? Perhaps you are experiencing a divorce, have family conflicts or are alone as an empty nester. These circumstances can impact your connection with family, colleagues, and most importantly, the relationship with yourself.

Isaac Martinez

All my clients come from very different ranges of needs. I specialize in clients who struggle with mental health and with substance abuse. A lot of clients have come back after completing treatment because they were so satisfied with the individualized treatment plan based on their needs.

Becky Salas

I often work with individuals and families who may be experiencing feelings of sadness, anxiety, or going through difficult times. I also provide guidance in handling life transitions, maintaining healthy relationships, and addressing childhood-related issues. I have extensive experience working with diverse populations.

Yoojin Nam

I work primarily with men who are looking to grow in their self-awareness and reach their greater potential in work, relationships, and personal life. I specialize in helping people manage anxiety, depression, and ADHD. I also encourage clients to explore the past, not so that they can get stuck there, but so that they can better understand and address the problems of the present to pave the way for their intended future.

Jen Hershey

We determine our self-worth by comparing our lives and judging ourselves against unattainable or unrealistic standards (hello, Instagram). I'm here to say, "I get it" and to provide breathing room when you don't feel like you’re good enough, or when you have hit your capacity. I work with individuals who want to feel better about their bodies and their relationship with food, people navigating a little thing called motherhood, those those hoping to get the most out of relationships.

G. Roman Gupta

My deepest wish is for you to know that you have everything you need in order to be happy RIGHT NOW.

Meghan Arroyo

I am an AASECT certified Sex Therapist, who works with individuals and couples who identify as LGBTQIA+, Kinky, Sex Workers, or practice Polyamory/Consensual Non-monogamy. I help any client interested in experiencing a more fulfilling relationship with sexuality or gender and is looking to heal from trauma.

NELSON ACOSTA

I enjoy helping people who need support and emotional stability. I specialize in depression, anxiety, PTSD, trauma, grief and loss, and past substance abuse.

Newport Academy Treatment Program

At Newport Academy, we address the root causes of self-destructive behaviors, not just the symptoms. We guide teens and their families to achieve long-term, sustainable healing by treating the underlying issues—such as trauma, depression, and anxiety—that catalyze substance abuse, eating disorders, and other co-occurring disorders. Incorporating clinical, experiential, and holistic modalities, our gender-specific treatment is family-focused and results-oriented.

Anna Athanasoulis

I specialize in supporting clients navigating challenges such as anxiety, depression, relationship issues, and trauma. My approach is compassionate and tailored to each individual, fostering a safe space for healing and growth. Through evidence-based techniques, I help clients explore their emotions, build resilience, and develop healthier coping strategies. Together, we work to uncover strengths, improve self-awareness, and create meaningful change for a more fulfilling and balanced life.
