Addiction therapists & psychiatrists in Rancho Cucamonga, CA

My name is Dr. Lentz and I have been practicing in the mental health field for over 10 years. I strive to help those acquire skills to overcome challenging situations that are tailored to a person's specific need. I am a goal oriented therapist that works diligently to achieve goals that are identified by the individual and myself. Life is full of situations that do not always have clear and definitive answers, which is a process the therapeutic approach I utilize can assist with.

I'm warm, pleasant, knowledgeable, professional, efficient and approachable.

My name is Claire Pinkston MS/MSC. I'm a Licensed Marriage and Family Therapist (LMFT) and a Certified Alcohol and Drug Counselor (CADCII). I’ve been in the counseling field for almost 20 years. I believe that we all face challenges engaging fully in life, owning our choices, connecting with other people, and making our lives meaningful. How we think about ourselves, others, and the future has a tremendous impact on how we feel and what we do. My goal is to help you understand the factors influencing your thinking, feelings, and choices, and make changes that will improve your life. I especially like working with people who are motivated to dig in and do the work, because change requires change.

I work with adults facing ADHD, anxiety, trauma, PTSD, sleep issues, and substance use, offering clear, practical help—no guesswork. You might feel overwhelmed, stuck, have trouble sleeping, or struggle to focus. We follow a structured approach to understand your situation and develop a treatment plan that progresses. I provide psychiatric evaluations, medication management, and focused follow-up using evidence-based and trauma-informed strategies. The process is simple, with clear steps and adjustments based on your progress. If you're ready to proceed, reach out.

I've found that building a strong relationship is the foundation of any successful therapy. My grounding philosophy is to meet people where they are at and to tailor my knowledge and experience to help them get to where they want to be. My ideal clients are those motivated, committed, and open to exploring various parts of the inner self and how these parts motivate, protect, grieve, and organize us for action.

I am a Licensed Marriage and Family Therapist (LMFT) based in Orange County, California, and working with clients statewide via telehealth. I work with adults and specialize in anxiety, relationship issues, substance abuse/addiction, and trauma.

My communication style is calm, accommodating, and reassuring. I want my clients to feel comfortable talking with me about anything, and I pride myself on my ability to listen without judgment.

I decided to become a therapist because I have always wanted to help people. Whether it was as an epidemiologist working with the physically ill, mentoring high school students in relational and life decisions, or being a loyal friend, I have always naturally been drawn to helping people through difficult times. Now, as a therapist, I get to enjoy seeing people realize their full potential, heal from their pain, and identify and begin working toward a new future of hope for themselves.

I am a Licensed Clinical Social Worker with over 15 years of experience in domestic violence, addiction, homelessness, severe mental illness, behavioral modification, individual and family therapy, relational conflicts, crisis intervention, advocacy, social policy, clinical supervision and program development.

I believe in the immense power of our thoughts and our incredible capacity as human beings to change them through awareness, intention and implementation. Together we will work to create the life you want to live despite the hardships you have overcame and any future struggles that may lay ahead.

I believe life’s hardships and tragedies have strength and the power to empower with self awareness and guidance through the pain.

I am a licensed Marriage and Family Therapist (LMFT) based in Orange County, California. I have worked in this field for over 13 years, and am committed to helping adult individuals from all walks of life navigate life's various challenges. My goal is for us to join together as a therapeutic team to help you better navigate whatever struggles life has thrown your way. I specialize in working with adults experiencing a wide array of concerns including, but not limited to, anxiety, trauma, mood disorders, attention-deficit disorders, relationship difficulties, struggles with self esteem, and various life stressors and transitions.

My Training

I am a licensed clinical psychologist and a graduate of the PGSP–Stanford Psy.D. Consortium, a program known for its rigorous academic training and emphasis on evidence-based care. There, I received instruction and mentorship from some of the leading clinicians and researchers in the country. My practice draws on specialized training and extensive experience in Cognitive Behavioral Therapy (CBT), Emotionally Focused Therapy (EFT) for couples, and comprehensive psychological assessment.

My Approach to Therapy

My clinical approach is focused, compassionate, and results-oriented. I work actively with clients to identify what’s holding them back, and to build the tools and insight needed to move forward with clarity and confidence. For individuals, I use CBT to help shift unhelpful thought and behavior patterns. For couples, I use EFT to deepen emotional connection, improve communication, and restore trust. Whether I’m working with a client facing anxiety, burnout, or relationship conflict, my aim is always the same: to help you reconnect with your strength, values, and capacity for meaningful change.

My Professional Background

Before becoming a psychologist, I served as a U.S. Marine Corps officer, including deployments to Iraq and Afghanistan. Leading diverse teams in high-stress environments taught me how to connect across differences—with people of all backgrounds, beliefs, and personalities. That experience continues to shape my work today. I bring a grounded, nonjudgmental presence to therapy, and I take seriously the responsibility of earning each client’s trust. My passion—both then and now—is helping individuals become the strongest, most authentic version of themselves.
