DEC-2025: Siyan Clinical has been a great experience for exploring who I was, who I am and who I can become. Mr. Poonlarp Lurslurchachai, NP, with his endlessly cheerful spirit, always encouraged me to Do better so I could Feel better. And Mr. Zachary Kahn, LMFT, demonstrated so much radical acceptance & patience with my far-fetched antics! I wish each one much success in Life's journey. Next up for me is IOP, which has been a welcoming, positive environment & I'm also getting acquainted with Mr. Craig Kleinman, MFT, whose style offers a cool, calm, casual approach to life. UPDATE JAN-2026: And Mr. John Wildgust has shown an efficient, thorough manner getting acquainted to take over for medication management. And, for IOP, my insurance is the same but the carrier had some billing changes from 3rd party to direct billing. So, I met with Noely and Daniela who were both extremely patient phoning my insurance with billing inquiries for the new calendar year. Everyone has been so caring. I'm very glad I came to Siyan for help. It's up to me to take action and to be more gentle to myself, but I am learning some new skills, next I must practice in real life.
