Bipolar disorder therapists & psychiatrists in Lexington, MA

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.

Choosing a therapist can be difficult. I like to help my client feels empowered in an affirming environment to meet their needs and goals.

I do not perform disability work.

I’ve been in practice for over 13 years since completing my postgraduate training at Harvard and University of California affiliated programs. I am board certified in adult, child, and adolescent psychiatry.

I’m open minded, non judgemental, and most of all, want to help. My private practice is just getting started, so I am scheduling patients on an immediate basis.

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.

My approach is client-centered, warm, and collaborative. I believe in treating the whole person—not just symptoms—and I often integrate evidence-based medication management with lifestyle and coping strategies tailored to your needs. I strive to create an inclusive, affirming space for all individuals, especially those from underserved and culturally diverse communities.

Whether you’re navigating trauma, grief, relationship challenges, or life transitions, I am here to support you in finding clarity, balance, and hope. My goal is to help you feel understood, empowered, and equipped with the tools you need to thrive."

Four decades. That's how long I've been doing this work — and I mean that not as a resume line, but as a promise. Over forty years of sitting with people through the things that crack a life open: the identity shifts that come with midlife, the isolation that quietly builds, the grief of a body that's changed, the exhaustion of caregiving for someone else while your own needs go unmet. I bring deep expertise in depression, anxiety, relationship challenges, and the complex emotional terrain that emerges as life evolves through its stages. I specialize in working with adults — particularly women, caregivers, and individuals facing chronic health challenges or major life transformations — who are navigating chapters of life that often go unacknowledged and underserved. If you've ever felt like the world was moving too fast while you were standing still, wondering who you are now and what comes next — this is the practice that was built for you.

Finding a provider can be challenging, overwhelming, and at times embarrassing. I have been in treatment for over 20 years, which prompted me to want to support other people like me. I am proficient in DBT as these skills have saved my life.

I am a woman in recovery, have been in psychiatric units, have a child with another woman, and attempted to end my life. I am healing everyday and you are part of that process.

I have worked with a variety of populations. I am passionate about working with other mental health professionals struggling with anxiety, depression, and trauma. I am honored to work with first responders (fire fighters, police, paramedics, doctors, etc). You are not alone. I understand the complex dynamics associated with seeking help.
