Addiction therapists & psychiatrists in Tustin, CA

Life is filled with ups and downs, which can seem overwhelming at times for many of us. Whether you are struggling with depression, anxiety, trauma, going through a stressful transition in life, or getting stuck in negative thoughts or beliefs, I am here to help you get unstuck.

I communicate in a direct but supportive manner, fostering an environment where you feel heard. Through active listening and structured feedback, we'll work as a team to identify challenges and set clear, achievable goals. Expect me to be understanding yet focused on guiding you to develop resilience and coping skills to overcome difficulties.

My goal is to work collectively as a team with you to identify current difficulties and assist your efforts to overcome these difficulties in a healthy environment where you feel heard and supported. Measurable treatment goals will be established and take priority for each client I serve.

I work with all ages and I'm trained in trauma based therapies such as CBT, DBT, and EMDR. I offer individual therapy using attachment based therapies, solution-focused brief therapy, and Gestalt self-compassion techniques. I'm not currently offering couples counseling except through private pay. I have worked with foster youth, caregivers, families, LGBTQ, and veterans. I have found my work to be professionally rewarding by assisting people in reaching their goals. I’m committed to meeting your needs and learning.

Anxiety and perfectionism have turned your mind into a battleground. Your inner critic nitpicks every interaction, leaving you exhausted by thoughts of “Damnit, why can’t I just be better!” Painful memories get louder, no matter how hard you try to ignore them. Daily invalidations of your Latina, queer, or immigrant identity sting, and you feel isolated as you keep your suffering to yourself. You’ve tried everything: doom scrolling, drinking, and self-help books, but nothing has worked. You're left feeling hopeless and weighed down.

Thank you for reading this. Having a background in grassroots and non-profit work as well as teaching, I am fiercely passionate about equity, social justice and liberation for all people. The therapeutic relationship is unique and radical --- your words have exquisite power and we get to think together about what they mean.

Lynda K. Cash, MA, LMFT (AKA; Lynda K. Martin)

Licensed Marriage and Family Therapist

Lynda K. Cash has over 17 years of clinical experience as a marriage and family therapist. Lynda has helped with individuals, couples and families gain insight and understanding regarding unhealthy/dysfunctional behavioral life patterns. Lynda is competent with facilitating plans of action for overcoming challenges with managing daily living needs and responsibilities.

In my studies at Antioch, I have specialized in Spiritual and Depth Psychology with CBT, DBT, Humanistic-Existential, Client-Centered, Gestalt Theories, Mindfulness, and based on my past experiences have developed a passion for working with a variety of diverse population from 12 years old children and their families to elder adults. I also took courses on World Religions and Women Role in Religion at CSUN, studied in Rabbinical School (AISH Ha’Torah) in Jerusalem, with Buddhist Guru in Nepal and a Hindu Guru in India with knowledge of Vedic (Vedantic), Hindu, Jewish, Christian, and Muslim Tradition.

For over 15 years being on spiritual path and self-discovery journey, I became a Spiritual Guide, Reiki Master, and a Minister. Lead Spiritual Retreats and trainings around the world, including, India, Nepal, Tibet, Russia, Ukraine. This experience prepared me to work with people from a diversity of backgrounds and cultures.

Worked with a vast variety of symptoms and problems providing needed support to my clients suffering from trauma, anxiety, depression, PTSD, low self-esteem. All of these issues and symptoms have a point to make for us to understand our selves better. Working with adolescents in Residential Treatment Centers, Transitional Youth Living Programs, adult and veterans of all ages, there is one common denominator - if you want your life to be better, we can find your individual path and you might become your own Master. We'll apply, or challenge, your believe system, to make positive changes.

I help my clients resolve their problems, learn coping skills, and set their spiritual and/or religious path. Increasing client's understanding of self and accepting life with all the pluses and minuses, learning from the past without the judgment might be a difficult goal to achieve.

My path into psychiatry is both professional and personal. I moved to the U.S. alone at 17 while navigating complex PTSD and periods of misdiagnosis, which shaped how I understand mental health today. I began with a bachelor’s degree in psychology at Nankai University, then trained as a nurse and nurse practitioner at Charles R. Drew University and Purdue University.

Over the past 7 years, I’ve worked across medical and mental health settings, developing an approach that balances clinical precision with individualized care. I specialize in anxiety, depression, bipolar disorder, and complex PTSD, particularly for individuals who feel stuck or haven’t found relief in traditional treatment.

I’m licensed in California, Virginia, New York, Washington, and Oregon, and provide care via telehealth.

Clients often describe me as warm, approachable, and easy to talk to. I aim to create a supportive and engaging space where you feel safe to be emotionally open, while also bringing a sense of ease.

At the core of my style is curiosity. I’m drawn to the “why” - why we feel, think, and respond to life the way we do. I take a holistic and at times existential approach, exploring not just immediate challenges, but the deeper patterns, life transitions, and questions of meaning that shape your experience.

I draw from a wide range of personal and professional experiences, including working directly with and overseeing a large and diverse group of clients. This allows me to adapt different techniques and perspectives to support growth, insight, and lasting change. Throughout the process, I remain thoughtful, engaged, and focused on what will be most helpful for you.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.
