Mark Green, MD

Addiction Psychiatrist and Founder

“It is such a relief to find a Doctor who actually listens to me, and understands exactly how I felt. For so long, I’ve felt frustrated, starting different medicines, feeling rushed in and out. It is wonderful to be making some real progress in my life at last.”

Mark graduated (UK version of) summa cum laude in Neurobiology and then completed his medical degree at University College London. He came over to NYC for his Psychiatry residency then an Addictions fellowship (Payne Whitney Clinic, New York Presbyterian Hospital, Cornell Medical Center), and later conducted research in the neurobiology of addictions at Rockefeller University. He’s been on Faculty at Cornell (Asst. Prof), Vermont (Asst. Prof), and Harvard (Instructor) Medical Schools. He is dually boarded by the American Board of Psychiatry and Neurology in both general psychiatry and addictions.

Since graduating in 1999, Mark has set up & run addiction treatment programs (NYC, Vermont), directed supreme evidence-based dual disorders programs, overhauled national addictions and pain programs (Kaiser Permanente, Colorado) and treated thousands of patients.

Mark is an expert psychotherapist. He is trained in many modalities: psychoanalytic, cognitive behavioral, solution-focused, motivational, hypnosis, and others. He’s currently receiving training in Accelerated Experiential Dynamic Psychotherapy. Dr. Green’s therapy approach is relational, pragmatic, structured, direct, and emotionally vivid.

He is an expert psychopharmacologist, remaining cutting edge without taking undue risks with you, using what’s tried and tested, and imaginatively minimizing side effects. He often helps people get off med cocktails they’ve been stuck on for years. He sees medications as facilitating psychotherapeutic change.

Mark completed training as a psychedelic psychotherapist with the Multidisciplinary Association for Psychedelic Studies (MAPS) in MDMA Assisted Psychotherapy for PTSD, and in Ketamine Assisted Psychotherapy (KAP) with Phil Wolfson at the Ketamine Training Center.

He has written many articles in neurobiology, psychiatry and addictions, and lectured at major conferences nationwide.

Drew Welch, RN

Registered Nurse, Family Therapist

“He’s the best nurse I ever worked with. We worked together for 6 years at WestBridge and I am really lucky he agreed to work with me at Psych Garden. He’s thorough, conscientious, caring, humble, courageous, honest and wicked smart.”

Drew Welch is a licensed registered nurse & therapist with over 20 years of experience working with individuals with co-occurring disorders as well as their families. He has extensive training in evidence-based practices including motivational interviewing, cognitive behavioral therapies, family therapy, vocational rehabilitation and integrated dual disorders treatment and has supervised and taught others these skills.

Drew was at WestBridge Community Services for 7 years as their nurse care manager, team leader and national wellness coordinator. Prior to that he was the Nurse Manager for the Co-occurring Disorders Unit at Bournewood Hospital.

Drew has more than 20 years of sobriety. He understands how impossible recovery can seem and that no single path works for all. He knows the importance of education, support and hope. These days he uses all his training, experience and passion to help others feel freer, prouder and more connected. Sometimes 12 step approaches help, sometimes CBT, sometimes a focus on exercise and diet (Drew recently completed his first triathlon). Side-by-side coaching can be invaluable to rebuild the self-confidence withered by addictions and psychiatric illness; so he’ll do that too.

Our Mission

To create a better future for our patients every single day

We are:

  • Focused on healing the core issues, not superficial tweaks. Lasting change needs deep therapies that rewire emotions and memories. Only then can people feel hope, expect success and experience connection and meaning.
  • True to your valued goals. Our agenda is your happiness and safety. We don’t tell you what you should do or judge you for your choices, whether those are about your relationships, medications, or drug use.
  • For complex people who deserve better. We welcome people others find too challenging, think it through and use whatever modalities are necessary to succeed.
  • An integrated team of doctors, nurses, psychotherapists, and life-wellness coaches selected for education, experience and character. We put our heads together daily to make sure we are doing our utmost for you.
  • Expert in the science. We use CBT, DBT, AEDP, EFT, CRA-FT, psychopharmacology including medication-assisted therapies for detox, maintenance and cravings.
  • With you over the long-term. Whatever is holding you back – depression, anxiety, trauma, addictive behaviors, relationship issues – we’ll figure it out with you, patiently, collaboratively, unfailingly.
  • Experts in moderation management and harm reduction.

Members of our team are or have been Harvard Faculty and are highly sought after supervisors and teachers. We offer the best treatment for psychotherapy, general and addictions psychiatry in the Boston area and northwest suburbs.

We use evidence-based practices including emotion-focused therapies (EFT), and we offer a boutique and concierge-type practice where your particular needs are carefully evaluated, met, and monitored; where you get a rapid response from a great team… and where you will feel truly cared about.

Our Values

Closing the gap between patient & therapist

What is Good Therapy?

Good therapy = a strong therapeutic alliance + specific targeted skills.

Too often, therapy can feel like venting to someone who is understanding. That’s all well and good, but people don’t need to pay for that. They can get that from anyone.

We believe that it is essential to:

  • Focus on valued goals,
  • Decrease avoidance behaviors,
  • Increase sense of control, and
  • Attain secure attachments.

At Psych Garden, we’re trained to maximize the therapeutic alliance and provide specific evidence-based therapies expertly. We measure outcomes so we know if we’re on the right track.

Our approaches are less specific to disorders and address issues common to many diagnoses. This is a trend evident in many centers of excellence1.

1. See, for example, the work of P Fonagy, A Caspi, D Barlow, A Abbass and D Fosha.

How we view addiction

  • No one starts using with the idea they may become addicted. It starts either as fun or as a way to cope, a way to manage feelings and different conflictual aspects of ourselves: There were some good reasons why the addictive behavior was so compelling.
  • Addiction changes the way our body perceives and manages stress via the stress hormone circuits. It changes the very way we feel about the dangers in the world and how we decide how to manage. While never the intention, we end up more anxious, more miserable, more reactive.
  • Addiction’s a learned habit, tugging on our thinking, changing our values & taking effort to resist.
  • We can come back from addictions stronger. We need to carve a new identity for ourselves but the resiliency is always there.
  • Abstinence is not always necessary. It is possible to learn to use moderately

How we view psychiatry

  • People need goals that they believe in, have innate strengths that guide them, and need help navigating the challenges that impede them.
  • Medications can be great but are blunt weapons without direction and therapy. Complex problems demand complex solutions.
  • All medications are poisons too: Sometimes less is more.
  • Emotions usurp cognition and people live more freely and fully when therapy helps us to tolerate, accept and use these instead of drowning in them or suppressing them.
  • Profound transformation and recovery do occur.
  • We’ve evolved over a long time but are stretching ourselves to fit a new world, violating honed biological processes and rhythms. We need to pay attention to our selves more carefully.

Treatment tailored to the individual

There is no one “right” treatment. Instead, at Psych Garden, psychological care follows careful diagnosis and the individualized application of evidence-based strategies. And it’s done kindly.

The goal is not to cease the behavior or use. It is to live safer, more fully, more connected and more mindfully. We follow a Harm Reduction approach, as best described by Andrew Tatarsky.


We believe

To change, people need to respond to triggers differently and stay away from triggers altogether. But to change deeply, in ways that go way beyond the addiction, that will make their whole life richer and more meaningful, people need to unwrap the emotions and thoughts that lie deep within automatic behavior, to face what has been avoided, to discover the stifled and stunted parts of themselves that need to be heard, need to contribute. We do this with you.
