Jacqueline Mosselle: Licensed Independent Clinical Social Worker

I am Jacqueline Mosselle, a social worker dedicated to supporting people to recover from trauma and other life stressors so they can live a life of joy, contentment and purpose. I strive to help people remove barriers that keep them from living the life they want and embracing their uniqueness.

 I am a Licenced Independent Clinical Social Worker with over 20 years of experience supporting people on their life journey to wellness. I earned a Bachelor's Degree in Psychology and Political Science from UMASS Boston in 1987. I earned a Master's in Social Work with honors from Salem State University in 2012.

 I have worked in multiple settings over the years. I worked at Germaine Lawrence as a residential staff member for 10 years and earned a staff excellence award. I worked for five years as a social worker at Catholic Charities' child care program and as a staff member in their women's homeless shelter. I worked for the Department of Children and Families for 20 years as a social worker and Supervisor, earning a Commissioner's Award in 2012.

 I was also employed by Lahey Behavioral Health as a mental health staff member in their CCS program and as an emergency crisis clinician. I am grateful and humbled by people willing to open themselves up to me and trust me with their burdens. I don't consider myself to have any specific specialty or client demographic.

I believe in helping whoever is in front of me at the time. When not in the office I enjoy church, walking my dog, exercising, playing with my granddaughter, reading and spending time with my sons.

Jennifer Gonzalez: Office Manager

Hi, I’m Jennifer. As the Office Manager at Square Behavioral Health LLC, I play an essential role in keeping our practice running smoothly while creating a warm, supportive environment for both clients and providers.Working in a close knit team, I manage scheduling, communications, and daily office operations. 



I understand that reaching out for mental health support can feel overwhelming, so I strive to make every interaction feel easy, welcoming, and stress-free. Whether I’m helping a client navigate their first appointment or supporting our team, my goal is always the same: to create a positive, compassionate experience where people feel at ease from the very beginning.

Being part of a smaller practice allows me to take a more personal approach, and I genuinely value the connections I build along the way. Creating a positive, compassionate experience is at the heart of everything I do.
