Hagar ter Kuile,
PhD, GZ psychologist
Welcome to the website of psychology practice HtK Therapy. My name is Dr. Hagar ter Kuile, healthcare (GZ) psychologist. I offer short-term treatments for various mental health issues. If you live in the Netherlands the costs are largely covered by basic health insurance. Treatment is possible both face-to-face in Amstelveen and online and is available in both English and Dutch. I have extensive experience in treating issues such as ADHD/ADD, depression, burn-out, anxiety and panic disorders, trauma/PTSD, migration and identity problems, parenting issues, and stress related issues. I use various therapeutic methods, including Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Schema Therapy.

Online therapy
Online treatment is an approachable and effective way to get help. It is proven to be as effective as on-site treatment. It also has many advantages:
Accessibility Therapy can take place whether you are at home, at work or on vacation.
How does it work?
- Initial consult 15 minutes: Free 15-minute consultation to discuss your needs.
- Intake A one-hour conversation to get to know you and discuss your help request.
- Session 1, Creating a Treatment Plan.: Customized treatment plan based on your goals.
- Sessions: Personalized treatment in person or via secure video calling. Average of 10-15 sessions.
- Evaluation and process: Regular assessments to measure progress.
- Closure: We work toward closure and establish a plan for relapse prevention.
Waiting List
A free introductory consult (15 minutes) is typically available within three business days.
June 2026: There is a five to seven week wait time, depending on your insurance.
Reimbursement
Treatment is reimbursed through the basic health insurance. The reimbursement depends on your type of policy and health insurance provider and is usually between 65% and 85%. I have a contract with Zilveren Kruis Achmea, which also includes De Friesland, De Christelijke Zorgverzekeraar, Interpolis, and FBTO. If you are insured with one of these providers, the treatment will be fully reimbursed after you have paid your deductible.
Client Experiences
I started therapy with Hagar not really knowing what I needed – “just” feeling exhausted stressed, and lost. From the very first session, I felt safe and genuinely heard. Over time, our sessions became something steady I could rely on. Whether it was work stress, anxiety, or just general overwhelm, Hagar always met me with patience and kindness, and helped me break things down into small, practical steps that actually fit my life. What made the biggest difference was learning to see my patterns more clearly, set boundaries, and respect my own energy. Nothing ever felt forced; we moved at…
Hagar is een hele fijne, oprechte vrouw om mee te praten. Ze staat zelfs voor je klaar op momenten dat je het niet verwacht. Ze heeft mij enorm geholpen om m’n leven weer op de rit te krijgen en de tijd genomen om te kijken wat er nu allemaal speelt. Als een behandeling niet werkte, keek ze mee naar de volgende. Ze neemt echt de tijd voor je. Mede dankzij deze vrouw zie ik weer een mooie toekomst voor me. Als ik iemand zou moeten aanraden dan is het wel Hagar!
Hagar is a wonderful, genuine woman to talk to. She’s there for you even when you least expect it. She’s helped me tremendously get my life back on track and took the time to explore what’s going on. If one treatment didn’t work, she’d help me move on to the next. She really takes the time for you. Thanks in part to her, I can see a bright future for myself again. If I had to recommend anyone, it would be Hagar!
I am forever grateful for the help and guidance that Hagar gave me during my sessions. She didn’t give up on me and kept supporting me. I felt heard and understood. She gave me safe feelings and tools for coping and it gave me strength to face my triggers. Her techniques are amazing, Honestly, my life turned to the better after having sessions with her! Thank you so much!
Hagar helped me when I needed the most. She turned my life to the better. I couldn’t thank her enough. She gave me great tools to cope, I feel heard and understood during all my sessions. She also gave me a safe place. If you are looking for a therapist who truly listens and guides you. Trust me, she is the one.
As someone who suffered a lot of anxiety, I would recommend HtK Therapy (although, I understand that even setting an appointment and showing up can be very scary in the beginning if you’re an anxious person, but you’ll soon learn that there is no need to be afraid). I used to be my own worst enemy – very highly self-critical and fearful of not being good enough. Over time it started to affect me physically too. After experiencing severe heart palpitations, I realized I needed help and put my pride aside. Online, I found HtK Therapy and reached out. From…
