About Us
Family-owned, Clinician-led, Community-focused
HM Behavioral Health was founded with the belief that high-quality behavioral healthcare can be both clinically excellent and genuinely human.
We are a family-owned, clinician-led behavioral health practice owned and operated by Hannah and Tommy McCann, providing therapy and specialized services to individuals and families navigating mental health concerns, trauma, addiction, recovery, relationship challenges, and difficult life transitions. While our services continue to grow, our philosophy remains intentionally simple: people deserve care that recognizes them as individuals—not diagnoses, problems to solve, or numbers on a schedule.
At HM Behavioral Health, we believe some of the most meaningful work happens when people feel safe enough to be honest, supported enough to explore difficult experiences, and empowered enough to begin making changes in their lives. Our clinicians bring professional training and expertise to that process, but we also recognize that every person who walks through our doors brings expertise of their own. Nobody understands your experiences, values, relationships, and goals better than you do.
That is why our approach to behavioral healthcare is fundamentally collaborative.

Hello! I'm Hannah, owner of HM Behavioral Health. We are a therapy practice in Buzzards Bay specializing in addiction, problematic gambling, trauma, recovery, and co-occurring mental health concerns. We provide in-person therapy services in Buzzards Bay and secure telehealth throughout Massachusetts.
We work with adults, adolescents, couples, and families, including people concerned about their own substance use or gambling, individuals maintaining recovery, and loved ones trying to understand how to support someone without losing themselves in the process. We also provide EMDR therapy and specialized substance use, RMV, court-related, and forensic evaluations.
Our approach is direct, compassionate, and practical. We look beyond surface-level symptoms to understand the patterns, experiences, and protective responses underneath them, while also developing tools that create meaningful change outside the therapy room.
Professional Background
I have more than ten years of experience helping individuals and families navigate addiction, recovery, trauma, problematic gambling, and mental health concerns. My background spans private practice, outpatient therapy, Partial Hospitalization and Intensive Outpatient Programs, community-based care, correctional settings, and recovery-focused services. Working across these different levels of care has given me a strong understanding of how clinical needs, relationships, family dynamics, and outside systems often overlap.
Throughout my career, I have worked with adolescents, adults, couples, and families at many different points in the recovery and healing process. Some people come to me because they are worried about their substance use or gambling. Others are maintaining recovery, working through trauma, or trying to manage anxiety, depression, and other concerns occurring alongside addiction. I also support family members who are trying to help someone they love while learning how to set boundaries and care for themselves.
As a licensed clinical social worker (LCSW), licensed drug and alcohol counselor (LADC I), Problem Gambling Specialist II, and EMDR Therapist, I bring specialized experience in both addiction and mental health treatment. My work is grounded in understanding the whole person, not reducing someone to a diagnosis, behavior, relapse, or difficult chapter in their life.
In addition to therapy, I conduct comprehensive substance use, RMV Risk of Recidivism, court-related, Chapter 111E, and other specialized evaluations. I regularly collaborate with attorneys, courts, probation officers, treatment providers, medical professionals, and community agencies. My goal is to provide evaluations that are clinically thorough, clearly written, and respectful of the person behind the circumstances.
I have also developed and facilitated family support, recovery coaching, alumni, trauma-focused, and psychoeducational programming. Whether I am working with a therapy client, a family, or someone seeking an evaluation, I aim to offer a space that feels honest, nonjudgmental, practical, and genuinely human.
What Therapy Is Like With Me
Many clients come into therapy feeling like they should already have things figured out or that they have tried everything before. Often the work involves slowing down and understanding patterns that developed over time, especially when those patterns once served a purpose.
Therapy is a space where you can show up honestly without needing to have everything sorted out beforehand. Together we work to better understand what is happening internally while building practical tools that support change in daily life.

Hi, I'm Tommy. I'm a therapist, addiction professional, and trainer. I've spent most of my career in the behavioral health and addiction field, but the part of this work I've always loved most is simple: getting to know people. I'm naturally curious, I ask a lot of questions, and I genuinely enjoy hearing people's stories—including the complicated, messy, "I've never actually told anyone this before" parts. My style as a therapist reflects that. I'm warm, conversational, pretty laid-back, and not afraid to use humor when it fits. Therapy is serious work, but I don't believe every minute of it has to feel serious.
Professional Background
I have spent my career working in addiction treatment, behavioral health, recovery, and community-based care. My experience has taken me through direct clinical practice, organizational and clinical leadership, program development, nonprofit work, professional education, and consultation. I've had the opportunity to work with individuals and families across the continuum of addiction and recovery—from people taking their first tentative steps toward change to those building meaningful lives in long-term recovery.
Before entering private practice, I worked extensively within addiction treatment organizations in both clinical and leadership roles. My experience has included providing direct therapy, developing clinical programs, training and supporting clinicians, improving continuing-care practices, and helping organizations translate good clinical ideas into things that actually work in the real world. I've also worked in the nonprofit sector, including supporting organizations focused on expanding access to recovery resources and strengthening recovery within the community. These different experiences have reinforced my belief that effective behavioral healthcare doesn't happen exclusively inside a therapist's office.
Education and professional development have also been an important part of my career. I've served as a professional trainer and educator in areas including Motivational Interviewing, substance use disorders, recovery, and behavioral health, and I genuinely enjoy helping clinicians develop their skills. I am a Licensed Alcohol and Drug Counselor I (LADC I), Certified Employee Assistance Professional (CEAP), Certified Clinical Trauma Professional (CCTP), and DOT-qualified Substance Abuse Professional (SAP). That's admittedly a lot of letters after someone's name, but each represents an area of practice that has meaningfully shaped the way I work with people.
My background also includes Employee Assistance and workplace behavioral health, including work with employees and organizations navigating substance use, mental health concerns, treatment, and return-to-work issues. That experience has given me an appreciation for how closely our mental health is connected to the rest of our lives—our careers, relationships, families, responsibilities, identities, and sense of purpose.
Across all of these roles, the part of the work I've valued most has remained remarkably consistent: sitting with people, understanding what matters to them, and helping them move toward something better. Whether I'm working with someone in therapy, developing a program, training clinicians, or supporting a community initiative, that remains the foundation of how I approach behavioral health.
