Welcome!
As a licensed Marriage Family Therapist (LMFT), I believe in prioritizing out mental health as a way to live a happy and balance life. Reaching out for help can be one of the hardest things a person can do, great job on taking that step! I’ve been practicing for 10 years, but in the field for 20 plus years. In the last 6 years I have shifted my main focus to adults 18 plus who are struggling with trauma and substance use.
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.
It has been a privilege to provide psychotherapy to a variety of clients for over 20 years. I have advanced clinical training in trauma, addictions, sexual abuse, mood and personality disorders, and relationships. My therapeutic style is warm, direct, and encouraging. I provide support as you examine core issues and change underlying patterns of behavior or simply gain perspective concerning a recent issue.
I have found my own personal healing to be intimately connected to nature, and it is here that I believe that we can all begin to rediscover our intrinsic humanity and let go of those things that distract us from our higher selves. In my spare time, I work as an outdoor educator and manage my own private practice and guide Outdoor Retreats
I believe it is helpful and important to translate what is discussed in session and in telehealth meetings into lived experience and real change.
I have a passion for coming alongside others and believe it's part of my DNA as a human being. I'm a mom, a Veteran, been married/divorced and I love my job! I specialize in trauma.. the big "T's" and the little ones. I have experience working with sexual assault, complex PTSD, moral injury, addictions, and grief.
