Trauma and PTSD therapists & psychiatrists in Colton, CA

My name is Dianne Fontaine, MSN, APRN, and I'm a Licensed Psychiatric Mental Health Nurse Practitioner, Board Certified (PMHNP-BC) by the American Nurses Credentialing Center (ANCC). I obtained my Master’s Degree from Walden University and has undergone advanced clinical training, equipping me to assess, diagnose, and treat a spectrum of psychiatric illnesses, as well as provide psychotherapy.

I am a California-licensed Marriage and Family Therapist with over a decade of experience providing specialized, confidential telehealth. My practice is built to support ambitious individuals—including busy professionals and dedicated college students—navigating high-pressure environments, life transitions, and relationship challenges.

Because your schedule is already packed with work or demanding coursework, I offer dedicated session times outside standard hours, including early mornings and weekends. Whether you are dealing with academic/professional burnout, family-of-origin issues, or deep emotional blocks, I provide a warm, inclusive space to unburden those patterns. I practice fluidly in English, Spanish, and Spanglish, honoring your unique cultural or bicultural lived experience.

I am skilled in helping adults of all ages heal from trauma. I also help my clients learn how to manage anxiety, including social anxiety, panic, and health anxiety. Beyond healing, I am committed to working with you to discover what matters most to you so you can take clear action and create the life you want.

Hello, I am a Licensed Clinical Psychologist based in California. I received my Doctorate Degree from Alliant International University in Fresno. I was born in Southern California and raised in the Bay Area. I have been practicing for 10 years and I enjoy empowering adults in their journey of overcoming their mental health challenges. I motivate clients for change and promote their personal growth.

I am a licensed psychotherapist with 20 years of clinical experience working with anxiety, depression and complicated relationships among many other concerns. I tend to use a more logic-driven, analytical structured approach with my clients where together we try to understand and analyze patterns of behavior that are causing problems and getting in the way of their lives. As a result, neurodivergents and people who work in the hard sciences, technology fields, or are business executives tend to respond very positively to my style and approach. I also work with mood disorders, unconventional or complicated relationships, historical spiritual abuse and military veterans.

Specialty in AI and technology:

I also specialize in the psychology of AI, technology and how it affects society and relationships. For 7 months last year, I spent extensive time within AI-user online communities to learn about their firsthand experiences involving AI-related harm and parasocial relationships. I was featured in the 2026 title How to Talk to AI (And How Not To) by BBC journalist and author Jamie Bartlett, where I discussed parasocial relationships in AI use.

Hobbies:

I love the outdoors, backpacking and going on road trips with my dog. I teach outdoor skills in a wilderness class each winter. I also love California native plants and am a trained naturalist.

Reaching out for help can be challenging for many. As psychotherapy aims at positive changes you desire, I am honored to provide a safe place for your self-exploration and reflection in which you can gain your inner peace and change you long for. Being specialized in trauma, PTSD, sexual abuse and domestic violence, I can offer some resolution in your trauma work. Trauma can penetrate not only your emotional well-being but also almost every facet of your life.

People come to therapy for different reasons. Sometimes something clearly isn't working. Other times, life may look okay on the surface, but you feel stuck, disconnected, or unsure about what you want next. I work with adults navigating anxiety, depression, grief, relationship difficulties, and major life changes, as well as those wanting to better understand themselves and the patterns that keep showing up in their lives.

My approach is warm, grounded, and curious. I’m interested in understanding what’s happening beneath the surface, including your thoughts and emotions, the patterns you've developed over time, and how your experiences show up in your body. Therapy can be a place to make sense of those experiences while finding ways to move forward that feel meaningful and true to you.

As a bilingual and bicultural therapist, I offer therapy in both English and Spanish. I strive to create a space where you can speak openly, feel understood, and explore your experiences in the context of your relationships, culture, identity, and the life you’ve lived.
