Addiction therapists & psychiatrists in Chelmsford, MA

Hi there, my name’s Ephraim and I'm a licensed Marriage and Family Therapist with 20+ years of experience. My specialties consist of relationships, men’s issues, career counseling, and psychosomatic illnesses.

Whether it's individuals or couples, I'm happy to get to work with whomever comes my way. I do my best to facilitate a warm, trusting environment. I received my Bachelors degree in Child Psychology, working initially with the adolescent population before transitioning over to adults. I then received my Masters in Marriage and Family Therapy. Looking forward to meeting with you soon!

I’m Sean Bourgeoise, a licensed therapist with a Master’s in Psychology. I specialize in helping adults and young professionals work through problem gambling, substance use, and anxiety. My style is supportive, practical, and focused on helping you build insight and create meaningful change.

I have 26 years of experience dealing with individuals, couples, families in therapy. We will work together to develop plans that are unique and right for you.

I earned my Bachelor of Nursing from University of Connecticut (Go Huskies!) before moving to Boston to start my career in bedside nursing in 2019. After serving as an RN and Director of Nursing at a residential treatment center, I earned my PMHNP at Regis College to specialize in mental health. Since then, I’ve gained diverse experience providing cutting-edge ketamine therapy in outpatient clinics and managing complex cases in inpatient psychiatry. Now, I’m bringing that clinical expertise—along with post-graduate training in CBT—to my full-time private practice, where I provide comprehensive, compassionate care for patients navigating anxiety, depression, OCD and ADHD in the South Boston area.

Choosing a psychiatric provider is a personal decision, and I approach that with care. As a psychiatric nurse practitioner specializing in adult mental health, I focus on understanding you as a whole person and creating a treatment plan that fits your life.

I have worked with diverse populations and often see how anxiety, trauma, stress, and executive dysfunction can interfere with work, relationships, and overall well being. I treat adults with depression, anxiety, ADHD, and substance use concerns, with experience in both inpatient and outpatient settings, including complex cases. I especially enjoy working with college students, professionals, and business leaders who are balancing demanding schedules and high expectations. I also collaborate with caregivers and other professionals to ensure well rounded care.

I am a board-certified Psychiatric Nurse Practitioner with a passion for integrative, whole-person care. By blending the principles of integrative psychiatry with a deep understanding of adult medicine, I am committed to treating the mind and body as a unified system. I believe that true wellness requires dedicated attention to both.
