Acceptance and Commitment Therapy
Learn more about Acceptance and Commitment Therapy, also known as ACT. Read below for a brief explanation of some of the main processes that guide what would be practiced in your session.
When pain knocks at our door, it can be difficult to remember what's most important in life. We get lost, make choices we regret, or take actions that go against our best interests, leaving anyone perplexed.
Acceptance and Commitment Therapy (ACT) and Clinical Behavioral Analysis (CBA) can help you live a more meaningful life and help you navigate the inevitable emotional and relational storms that visit us from time to time.
Whether your need is more "internal" (related to self-esteem issues, or painful emotions and thoughts) or "external" (you want to change a specific behavior, quit an addiction, or learn social skills, for example), therapy can help you change your perspective, find new and unexpected possibilities, and engage in much-desired actions.

Frequently Asked Questions
1. How do the sessions work?
I always offer an introductory session to get to know you better. After that, sessions are usually weekly and last 50 minutes.
2. What is the price of the sessions and the payment method?
The price is agreed upon during the first session. I strive to be flexible and find a solution that is sustainable for both of us, as I prefer to prioritize the quality of treatment. Contact me via WhatsApp for more details.
3) Do you accept health insurance plans?
I don't directly accept health insurance plans, but I issue invoices that can be submitted for reimbursement to most insurance companies. Some plans reimburse 100% of the session cost. Check with your insurance company to find out the reimbursement conditions for your plan.
