Founder, Executive Director


David McNamara is a Recovery coach, Substance Abuse Counselor, filmmaker and Zen practitioner. David is currently completing his certification in Harm Reduction Psychotherapy with Dr. Andrew Tatarsky (one of our advisors and collaborators.) David has worked and volunteered in the recovery field for over 10 years as well as having  training in Mindfulness Therapy and meditation. Prior to this he was a filmmaker for over 30 years. After many years into his own recovery he began to see the need for alternatives in the way that we treat addiction and the trauma underlying the addiction. In keeping with the contemporary wisdom for the treatment of addiction, David has spent much of his career investigating how recovery, spirituality and creative expression are integrally related. He began to develop a practice based on his own experience of recovery. Using his  Zen meditation experience, DBT training, and Harm Reduction Psychotherapeutic techniques he began a program called Mindfulness Based Recovery. He has implemented this practice into his work at a traditional Drug Treatment center with some very promising results.

Last year David embarked on a documentary film called “Disconnected” (Healing an addicted society). In the making of the film he has found an incredible group of therapists, teachers, mentors and advisors. In many ways meeting and interviewing these authors of the paradigm shift in the way we treat addiction gave birth to this idea and this center.

In my role as Executive Director of Samadhi I will guide the overarching philosophy of treating addiction with compassion, understanding and mindfulness. I will be responsible for finding new therapists and treatments along with experts in their respective fields. Samadhi will be a living, growing entity working together with our research department and staff to continually evolve.

Family Physician

Maya Hambright, MD is a Family Physician who has been raising her two daughters and practicing medicine in the Hudson Valley for 20 years. She grew up in Washington DC, the daughter of a Chemistry professor at Howard University and a high school Social Worker at the very diverse public school TC Williams. Education, equality, and accessibility for all, was bred into her.

As the opioid crisis tore through her town of Woodstock, overdose tragedy struck close to her family. Her practice now is primarily based on addiction and healing practices. She has spend the past 10 years working with both inpatients at Samaritan Village Daytop and outpatients at Maverick Family Health, part of the HealthQuest organization.

Maya is a prescriber of traditional MAT (Medication Assisted Treatment) and mental health medications, though has become increasingly aware of the limitations of traditional methods. And furthermore is acutely aware of a divergence in the previous styles of substance abuse treatment and in newer modalities. She has been introducing mindfulness and meditation into her medical practice however has had no formal training. As a believer of community and collaboration, she has joined Samadhi, as a place to refer her patients and as a place to further her own discovery and growth.

“We need to address both the mind and body in order to help our clients heal from the trauma and suffering that accompanies addiction. As providers we need to have and show empathy for our clients. We can then model for those struggling to learn empathy and forgiveness for themselves and for others. Without self love and self respect people continue to make unsafe and damaging decisions. As treatment providers we also need to coordinate our care with local community organizations - because without safe housing and food and healthcare - people continue to be forced to make unsafe and damaging decisions. Samadhi will be the much needed intersection of mind, body, community, and wellness in the recovery world.”

Director of Nutrition and Holistic Detox Services


Luis Mojica CHHC is a certified holistic healer, nutritionist and herbalist. He was challenged with trauma, eating disorders, illness, and the Standard American Diet. When a close friend died of a sudden heart attack, his mother bought him a juicer and his healing journey abruptly began.  He juiced, sprouted, breathed, read, studied, and practiced what he was reading and preaching until he cured every incurable disease he was afflicted with - cystic acne, severe asthma, high cholesterol, weight issues, crippling anxiety and insomnia to name a few. I went on to study Psychology, holistic nutrition, life coaching, and somatic therapy. Each modality gave me new tools to, first, heal myself and then help others heal themselves. 

“My personal traumas turned out to be incredible gifts. They motivated me to learn unique healing modalities out of a personal need to heal. They've also allowed me to have experiential empathy and understanding for others, so that I'm able to truly understand where someone is and help them. I find that more valuable than my training even.

In addition to my own journey and studies, I spent a decade working in NYC wellness centers, consulting for wellness businesses, and working with thousands of people directly from every background and with every story imaginable. From there, I started to develop my own form of healing that incorporates herbs, nutrition, and counseling. In 2012, I launched my private practice and have been enjoying it ever since.”
