Addiction therapists & psychiatrists in Arlington, MA

I have been in human services for over 30 years. I am see individuals over 21 years of age. I am an LICSW and accept most insurances. Most of my experience is in trauma, substance abuse, anxiety and relational issues

Hello, and welcome. I am Shereda Grossett, MSN, PMHNP-BC, RN. I am a board-certified Psychiatric Mental Health Nurse Practitioner with extensive experience caring for individuals across a variety of mental health settings. My background includes leadership in inpatient psychiatry, nursing education, and direct patient care.

I specialize in the assessment and treatment of anxiety disorders, depression, bipolar disorder, ADHD, trauma-related disorders, mood disorders, and other psychiatric conditions. I believe that mental health care should be collaborative, compassionate, and individualized. My goal is to create a safe, nonjudgmental environment where clients feel heard, respected, and empowered throughout their treatment journey.

I am a down-to-earth, approachable therapist with over a decade of experience supporting teenagers, young adults, and their families. Many clients arrive hesitant about therapy but quickly find a comfortable, nonjudgmental space where they can talk about anything. I strive to be responsive to each person’s life experiences, including gender- and race-based toxic stress and trauma. I completed my training at Boston University and spent several years working with a multidisciplinary team at a safety-net hospital.

I strive to help clients by being curious, kind, reliable, and insightful. This is how I believe therapy helps people to grow, and to ultimately feel better about themselves and their lives.

I primarily work through a psychodynamic lens, focusing on a client's emotional life, exploring connections between a client's past and present, and addressing internal conflicts. I also use ideas found in Cognitive Behavioral Therapy such as exploring thought patterns and negative core beliefs.

I am passionate about working with people to understand and overcome things such as anxiety, depression, coping with issues relating to the Covid pandemic, anger and mitigating substance use.

I am a board-certified psychiatric nurse practitioner. I earned both my Doctor of Nursing Practice and Master of Science in Nursing degrees from Columbia University. My clinical training includes experience in outpatient community health, school-based mental health, private practice, and child, adolescent, and adult inpatient psychiatry. Prior to becoming a nurse practitioner, I worked as a registered nurse in a detox and rehab facility serving individuals with substance use disorders, including low-income, formerly incarcerated, and unhoused populations.

I work with adults who want to better understand their thoughts, feelings, and behaviors so they can feel less overwhelmed by anxiety or depression. Together, we’ll explore what’s happening beneath the surface and develop practical tools that support both your immediate relief and your longer-term goals. My approach is collaborative, thoughtful, and paced to match where you are right now.

I believe that healing happens through genuine connection. As a Licensed Independent Clinical Social Worker (LICSW), I strive to create a safe, supportive, and judgment-free space where clients feel heard, understood, and accepted. I work with adults experiencing anxiety, depression, trauma, substance use, life transitions, relationship challenges, and low self-esteem.

My goal is to meet you where you are. Whether you’re feeling overwhelmed, stuck, or simply ready for change, we’ll work together to better understand your experiences, build on your strengths, and move toward the life you want to create. I believe therapy should feel collaborative, empowering, and tailored to your unique needs.

For the past 3.5 years, I’ve had the privilege of leading a multi-site inpatient unit, supporting individuals with persistent mental illness and substance use as they work toward stability and recovery. Now, I’m stepping into private practice and writing my next chapter. I’m licensed in Florida and passionate about making care accessible and meaningful. I’d love to connect—does this sound like a fit for you?
