Meet Guillermo Diaz

Close personal experience with mental illness brought me this field and I bring unique insight and a deep passion for helping others on their mental health journeys.
A bit about my approach to therapy
Known for being easy to talk to, together we will create a safe, supportive space where you can feel heard and understood. Specializing in conditions such as anxiety, depression, bipolar disorder, and dementia, I provide personalized, evidence-based care, including medication management.
What you can expect from our first session
Committed to helping individuals thrive, I believe mental health care should be empowering, respectful, and easily accessible. Goals will be established together and we can work towards these goals as often as you feel comfortable.
