Our diverse team is made up of innovators, clinicians, administrators, social workers, business professionals, dietitians, nurses, mental health counselors, psychologists and doctors who are all dedicated to helping all individuals receive the specialized care they need and deserve.

“We have a group of incredibly talented people with an extraordinary level of heart. I know this is what sets us apart from other organizations as a place to work and as a place for our patients to experience healing.”– Stu Koman, Founder and CEO of Walden Behavioral Care

Stuart Koman, Ph.D.
President and CEO

Ten minutes with Dr. Stu Koman and you can understand why he has had such a profound impact on the lives of his patients, their families and the hundreds of people who have been fortunate enough to work alongside him. Stu is a visionary. He is a thoughtful, empathetic and persuasive leader whose mission is bold and whose commitment to that mission is brought forth through the teams at Walden each and every day.

Stu founded Walden Behavioral Care in 2003. His tenacious and passionate spirit has been the driving force in the company’s growth to 15 locations up and down the east coast. You are as likely to find Stu running adolescent groups for our residential program and consulting with clinicians on complex cases as you are to find him sharing a refreshed strategy to the Board of Directors.

Since beginning his professional career in 1981, Stu has revolutionized the way individuals and their family’s access and receive mental health care. Fundamentally, Stu believes in creating opportunities for underserved and low-resourced populations to receive top-quality mental health care. As such, he has developed and managed several successful behavioral health care companies including Charles River Hospital and health management in Wellesley, MA, where he developed innovative treatment models for adolescents in hospital settings, and Choate Health Systems, Inc. (CHSI), where he introduced the continuum of care model that offers varying levels of support under one administration. Stu is a lecturer at Tufts School of Medicine, a member of the APA and MPA and a board member of the American Association of Mental Health.

In his “down” time, Stu loves traveling the world and exploring new cultures and terrain on his bicycle. He serves on the board at “Cycle Kids,” a not-for-profit whose mission is to encourage healthy and fun movement for children by teaching them the practical skill of riding a bike. Most recently, Stu is delighting in his new role as “Zayde” (Grandpa).

James M. Greenblatt, M.D.
Chief Medical Officer & Vice President, Medical Services

Dr. G, as we lovingly refer to Dr. James Greenblatt here at Walden, is a rare and wonderful person that we are fortunate enough to have as a leader. He is inspiring, witty, warm and welcoming to all. He is a brilliant and fearless innovator with a comforting demeanor that fosters truly collaborative alliances with each of his patients and our medical and clinical teams alike.

Dr. Greenblatt is an internationally – recognized pioneer in the eating disorder and integrative medicine fields. Board certified in child, adolescent and adult psychiatry, he understands that all individuals have unique biochemical profiles that lead to a range of different behaviors and, therefore, treatment needs. His interest and research in the integral role of nutrition in psychiatric outcomes and the interrelatedness of all body systems have changed the lives of countless individuals whose psychiatric symptoms persisted despite the use of traditional psychopharmacological interventions. As our chief medical officer and vice president of medical services, Dr. Greenblatt utilizes these key concepts with patients and provides medical management, leadership and oversight of all our psychiatric programming.

Dr. Greenblatt received his medical degree and completed his adult psychiatry residency at George Washington University in Washington, D.C. He completed a fellowship in child and adolescent psychiatry at Johns Hopkins Medical School.

Dr. Greenblatt also serves as a clinical faculty member in the psychiatry department at Tufts Medical School. He lectures extensively throughout the United States and Canada on integrative therapies for mental health. Additionally, he is the author of “Answers to Anorexia,” “The Breakthrough Depression Solution,” “Finally Focused” and “Answers to Appetite Control.” A lover of the performing arts and music, there is rarely a performance in Boston that Dr. Greenblatt has not seen or have an opinion on and it is unlikely there is a coffee shop in the metro Boston area that he hasn’t tried.
