Obsessive-compulsive disorder therapists & psychiatrists in Cambridge, MA

Hi, my name is Rachel Register and I am a licensed independent clinical social worker who has been in practice in Massachusetts as well as New Hampshire for over 10 years working with adults, couples and families. I feel passionate about healing and empowering clients who struggle with anxiety, depression, relationship issues and life transitions.

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 do Individual, Couples, Family, and Group Therapy. I currently facilitate a Bereavement Group which meets at my Brookline office every Saturday from 2-4pm. I also run groups for substance abuse, depression and anxiety. In addition, I have a lot of experience counseling children of all ages. I am a firm believer in strength-based psychotherapy.

With 165+ reviews and a 4.96 rating on Zocdoc, I have specialized in advanced medication management for complex, treatment-resistant conditions. I utilize a neurobiological approach that focuses on frontal lobe/executive functioning, nervous system dysregulation, and neurotransmitter systems to diagnose and treat various concerns - ADHD/executive dysfunction, OCD, trauma/C-PTSD, high-masking autism, personality profiles, and cases where standard medication treatments have failed. While I specialize in clinical complexity, I bring that same deep, careful attention to treating anxiety, depression, and clients starting medication for the first time.

I grew up in MA. I went to both public and catholic schools. I earned a 2nd degree black belt from Premier Martial Arts. I earned a BA in Psychology from UML. I worked at a group home for teenagers, then one for adult men with schizophrenia. I worked as a support and then a lead teacher at a day program for adults with developmental disabilities. There, I learned a lot about Behaviorism and ABA. I was then able to work as a clinician as I finished my graduate degree.

I earned my graduate degree at Fitchburg State University. I did my internship at the Community Health Center in Fitchburg. I worked in community mental health before venturing out on my own.

I am a Family Nurse Practitioner (FNP) and Psychiatric Nurse Practitioner (PMHNP) with a strong background in both primary care and mental health. With experience in treating individuals across the lifespan, I focus on delivering compassionate, patient-centered care that addresses both physical and mental health needs.In addition to my primary care expertise, I specialize in addiction treatment, offering evidence-based strategies such as medication-assisted treatment (MAT) and behavioral therapy to help patients overcome substance use disorders.
