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 knows an awful lot of medicine – general, sleep, pain, neurology and other areas. He came over to NYC for his Psychiatry residency then and 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.
He has written some articles in neurobiology, psychiatry and addictions, and lectured at major conferences nationwide.
Drew Welch, RN
Nurse, Program Director, 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.
Jonathan Entis, PhD
Jonathan Entis is a licensed psychologist providing psychotherapy to adults across the age span. His areas of interest are anxiety, depression and other mood disorders, relationship and personality difficulties, addictions, trauma and major mental illness. He has particular expertise in treating individuals who have found other forms of treatment unhelpful or ineffective.
While his training has involved a range of therapeutic models, he approaches each person as a partner in therapy and tailors his approach to the unique needs of the individual. He tends to work from an Intensive Short-Term Dynamic Psychotherapy (ISTDP) approach. This model involves an active and concentrated focus on emotions and the ways in which blocking or avoiding them contributes to suffering. ISTDP can be challenging but aims to produce rapid and profound change from the beginning of treatment. It helps individuals take an honest look at the feelings and experiences that they have not been able to shed so that they can finally move beyond them and live the life they want.
Jonathan did most of his clinical training at Harvard Medical School, including a doctoral internship at Harvard/Cambridge Health Alliance and a placement at Harvard/Massachusetts Mental Health Center, and a post-doc at Tufts University. He holds a PhD from Northeastern University, an MA from Boston College, and a BA from the University of Michigan.
In addition to his clinical work, he maintains an active academic career and has published a number of papers on topics covering severe mental illness, ethics, neuroscience, and psychotherapy. He has taught graduate and undergraduate level courses at universities across Greater Boston, including Northeastern University, Boston University, and Boston College. He currently teaches at Harvard Medical School/Cambridge Health Alliance.

Carolinda Sterczala, LICSW
Carolinda uses her warm and compassionate approach to help clients gain safety, comfort, and familiarity with their own emotional worlds. As emotions become a trusted guidance system, a healing process begins, a sense of self-grows, and relationships become more understandable.
Integrated expertise in various modalities helps with this process. AEDP is all about emotions, interconnection, how healing happens, and how to enhance it. EMDR greatly helps unlock the brain’s adaptive capacities after a trauma, and also useful in behavioral addictions. Circle of Security Parenting, or COS-P, distills decades of attachment research into useful bites to help us know what is needed and that we are capable of providing it. Carolinda makes COS-P available for interested parents but also for some of us looking at our own attachment histories, in a way that often “clicks” for people. Carolinda is also excited to lead DBT skills groups again, as naming and focusing on these skills has been part of many “spirals upward” she’s been fortunate to witness in the past.
Carolinda has had various roles in Massachusetts cities since 2000, including DBT program coordinator, Clinical Director, and Private Practice Clinician. Her B.S. is from Cornell University and her M.S.W. is from Boston University.
