Mark S ClossonPsychologist, PhD

About

Thank you for visiting my page, and welcome to my practice! I have offices centrally located in Hauppauge and Garden City. I accept several major insurance plans, and will help clients on other plans obtain out of network reimbursement. I work primarily with a few groups. I work with many couples with marital issues, and with parenting issues. I help with many adolescents and college students navigate the trials and tribulations of life. Finally, as an expert in ADHD and learning disabilities, I offer state of the art psychological and psycho-education assessment.
