Keystone Psychological Services provides comprehensive programs and interventions grounded in Cognitive Behavioral Therapy (CBT)

Why choose the CBT approach?

CBT helps you make steady progress in the present by teaching practical skills to manage thoughts and actions. It grounds you in the here and now, clarifies where you want to be, and guides focused behavioral steps toward both short‑term and long‑term goals.

Hear From Our Clients

  • Thoughtful and Balanced Help

    “Dr. Diaz served as my therapist during the course of what for me was a ‘surprise’ divorce. She was a source of thoughtful, balanced strength as she skillfully assisted me in navigating this emotional life passage. Beyond helping me understand the interests and motivations of others during this period; Dr. Diaz assisted me with the difficult, but critically important, task of holding up a mirror to myself. In working with Dr. Diaz, I received invaluable life skills that are tantamount to the difference between being ‘handed a fish’ versus being ‘taught to fish’ for oneself. Dr. Diaz is a whip-smart, warm and compassionate clinician and I recommend her highly.”

  • Safe and Supportive Environment

    “I am a police officer who experience a job-related traumatic event, and was having some difficulty handling it. There is a stigma in my profession about seeking help because you will be seen as weak. I can’t thank Dr. Diaz enough for creating a safe and supportive environment for me. I’m not one to talk about my problems, but I can tell you that now I do not hesitate to pick up the phone and call for her exceptional guidance”

  • Compassionate Clarity, Guiding Growth Through Life’s Crossroads

    “Keystone and Dr. Ingrid Díaz’s services have helped me through multiple critical crossroads in my life - from post-partum experiences to problems with toxic relationships and matters in the professional workplace. Their approach is compassionate yet direct, holding me accountable while simultaneously validating my experiences and centering my own agency in my problems and solutions. I often find the little voice in my head during a tough moment sounds like Dr. Diaz, and I look forward to each next conversation! I highly recommend Keystone and her to anyone seeking to understand themselves more deeply and take ownership over how to overcome challenges.”
