What does a first session with you look like?

The first session, as with all Thriveworks therapists, will involve talking through your needs and goals for therapy — whether those involve managing depression, anxiety, relationship problems, or another mental health challenge. This will enable you to receive the very best care, as a personalized treatment plan will then be developed for subsequent sessions. Thriveworks helps people live happier, more fulfilling lives. Clients are guided and supported as they work through their unique mental health challenges – and, along the way, shown the life-changing power of therapy.

What is your style/approach to therapy?

I offer a variety of counseling approaches including CBT / Cognitive Behavioral Therapy, Family Systems. Living in our world can be stressful and overwhelming at times; I would like to provide a safe place for you be heard.
