  • Marybeth Greenberg LMHC (Massapequa)

    I completed my Bachelors degree in Psychology with a minor in Criminal Justice at Long Island University in 2020 after being a Division II and Division I Field hockey goalie on the NCAA academic squad. Immediately after graduating undergrad, I continued my education at LIU and completed my Masters in School Counseling in May 2022, and then continued on to get my Masters in Clinical Mental Health Counseling which was completed in May 2023. In between my masters program I had completed an EMT-B program in Brooklyn and then utilized those skills to work as a Spravato tech and TMS technician at another practice until I started working at Evolve. I'm a strong advocate for the mind, body, and soul connection when it comes to therapy and using a client centered approach, as well as utilizing mindfulness techniques alongside Cognitive Behavioral Therapy. I look forward to offering a peaceful and judgement-free space for my patients to express themselves freely and evolve themselves through a journey of self-discovery and self-improvement. When I'm not at Evolve, I'll be snowboarding at a local mountain or chasing the sun to a beach and some surf!
