Carly Clement​

Director of Business Development

Director of business development for Orange County drug rehab

I enjoy being present for every moment…every, single moment of my life since I found sobriety.  I’ve found that meditation and music fill my soul and that tapping into what fills your soul is key to success in recovery.  My education in substance abuse, mental health and intervention training for men and women in recovery is a strong foundation, but my personal experiences are what make me so relatable and approachable.  I find that being vulnerable and sharing my experience allows me to truly and authentically connect to others.

I’ve been working in the behavioral health field for over 7 years and I am very passionate about helping others struggling to find their purpose.  I embrace the approach of “Let’s do this together” and looking at how we can make our lives better, to look forward to what you can achieve and not back at what you may regret.

Adrian DeBrey, RADT

Facility Manager

Operations Manager for Orange County drug rehab

I am the Operations Manager of Coastal Addiction Center. I’m a certified life coach and group facilitator.  I’ve been immersed in the recovery community since 2015, and find purpose and passion in helping those struggling with addiction.  I strive to bring compassion, understanding, and awareness while providing hope and safety to the community. In addition, I am an affirming advocate for the LGBTQIA+ community and individuals exploring their authentic selves. Equally important to my professional life, I have a zeal for art, music, philosophy, and writing. I delight in expanding upon my spirituality and reading books which allow me to broaden my perspective, that is, when my lovable wife, imaginative daughter, and Chiweenie “Atticus” are not pulling me away to collect
rocks and build forts in the backyard.

Sue Mannos, MS, LMFT #110222

Clinical Director


I am a Licensed Marriage and Family Therapist with 25 years of experience working with substance abuse, trauma, dual diagnosis, PTSD, mood and anxiety disorders. I have worked with clients in a variety of treatment settings, including detox, residential, intensive outpatient clinics, non-profit organizations, and private practice. I have a Masters in Marriage and Family Therapy from California State University Long Beach in 1994 and have been working primarily with clients in the acute trauma and substance abuse population. I bring a strength and evidenced-based approach while using a variety of therapeutic modalities, including cognitive-based therapy, dialectical-behavioral therapy, psychodynamic, mindfulness, and relational therapy. I believe we are all capable of growing and moving toward positive solutions while facing challenges.  I work to create a compassionate and empathic healing space that leads to deeper insight, positive change, and a healthier sense of self
while helping clients learn to stand on the foundation of recovery.

Dann Buongiorno, CATC

Program Director


Anger Management Professional

Program Director for Orange County drug rehab

“I have been an active member of the local recovery community for over 11 years and have been able to find a true calling in my life while exploring the world through the lens of recovery. I believe I have taken my liabilities and turned them into assets for the assistance of others.“

I am the program director here at Coastal Addiction Center.  I have been working in recovery for over ten years and have been able to obtain certifications with CADC, CATC, RAS as well as become an Anger Management Professional.  I began my career counseling in county-funded indigent programs and worked my way to the program director position here at Coastal Addiction center.  This was accomplished over 10 years of professional development.

    One of the things I immediately sensed here at Coastal is the true sense of family among the staff.   Everyone works together in service towards the common mission of obtaining and maintaining sobriety for all who enter the program.

Case Manager

Case Manager for Orange County drug rehab

I love what I do! I am a case manager here at Coastal Addiction Center.  I just completed my schooling for my CADC and doing what I love while I obtain my intern hours.   I’ve been working in the recovery field for 5 yrs and I can’t imagine doing anything different. I love showing people who struggle with addiction that there is hope while creating meaningful relationships in recovery.  I have over 6 years clean and sober, I understand the struggle, I’ve been where my clients are at. One day at a time.

Dianna Brown

Medical Supervisor


I’ve been a Medical Assistant for ten years. I worked in mental health for 6 years. I really never felt at home until I started to work in treatment.  There is something so rewarding about
watching the darkness of despair fade away and the spark of hope start to illuminate in someone’s Life. If I have the privilege of being a part of that transformation in some small way it
makes it all worth it. I don't think I was made to do any else!!

Monique Edwards, LVN​


My name is Monique. I have been a nurse for 7 years and have had the pleasure of working in recovery for 3 years.  Although not in recovery myself, I chose to work in recovery because I’ve dealt with addiction in my family.  I know the struggle and the heartbreak, I wanted to do something in my career that combines both my experience as a nurse and help patients through what is often a very difficult time for them.  I take pride in caring for each and every one of my clients.

Nicholas (Niko) Castillo

Medical Assistant

Medical Assistant for Orange County drug rehab

One of the most rewarding experiences for me is working in addiction treatment.  Witnessing the growth in others, knowing I played a small part in that is huge for me.  Being able to assist each client with a tool that can give them a better chance towards a new life is the most fulfilling feeling.  I've able to realize my passion while working with others who struggle with addiction.  I have recognized that I have the ability to connect with almost all the clients who come through our drug rehab facility.  It's an amazing feeling to hear from each client that completes our program and seeing where they’re at on this new journey.

Beth Wonder

Care Coordinator Supervisor

Registered Addition Specialist for Orange County drug rehab

Hi, my name is Beth Wonder.  I am a recovering alcoholic with a sobriety date of February 21, 2009. I have worked all 12 of the steps and continue to do them on a daily basis to maintain my sobriety.  I like working in treatment because I enjoy helping others that have suffered from the disease like I have and I want to show them that there is a better life beyond addiction.  I recently finished college courses to get my CADAC.  I’m currently working on my intern hours so I can become a case manager to better help others suffering from drug and alcohol addiction.

Ryan Skinner, RADT

Care Coordinator

Registered Addicton Specialist for Orange County drug rehab

Student at California State University, Fullerton studying Environmental Health Science.   Sobriety Date March 29, 2014.  4 years clean and sober.  I am passionate about helping other alcoholics and addicts because I understand, I became clean and sober at age 22 after living in the throes of my addiction for 9 years.  When I came to the realization that I was powerless over my addiction and surrendered my will to God, I was given a new way of living which has proven to be a life beyond anything I could have imagined. Working in recovery, I have been entrusted with caring for people who need compassion and love just like I did.  My goal is to help clients at our drug and alcohol rehab discover they are worth so much more than they realize, and that they hold the ability to accomplish their dreams. I am devoted to helping our clients see the possibility of breaking the chains of their addiction, and in the process watching them transform their lives into a new way of living which can transmit into every part of their existence.

Jon Washington, RADT

Care Coordinator


My sobriety date is August 6th, 2017. This is my first time ever in recovery and relapse has not been a part of my story. I started working in recovery about 16 months ago. I immediately knew this is what I wanted to do; I enjoy every minute of it. I enjoy helping people who are struggling with addiction, sharing my story and seeing that light in their eyes when they realize recovery is possible. I spent my first year in sobriety at concepts, while I was there, I learned what being accountable meant, I became a responsible person and was able to build my foundation in this program.
I want to show the newcomer it’s possible for them too. I know exactly what they’re going through. I want to be able to give them hope to be able to achieve anything they set their mind too. My passions outside of work are bowling, music, and pool. Fun in recovery is possible…….

Care Coordinator

Hey guys! My name’s JT. I’m a Southern California native and proud to say this is where I found my true Fellowship. A Roque Center Alumnus, I have a sobriety date of December 27th, 2017 and deeply believe in the idea of Recovery through Service. I have been involved in the growing LGBTQ+ AA Community for the vast majority of my sobriety, including the Pride in Sobriety Orange County Alcoholics Anonymous Convention (PISOCAAC) and several meetings in the North Orange County area. I have worked in many different fields, including the music industry and veterinary medicine, but have found my true calling in Treatment. To see others recover from a seemingly hopeless state of mind and body on a daily basis will always be considered the biggest blessing in my life. Each and every day is a new opportunity to grow, learn, and ultimately help improve the lives of those around me. Through my own experiences, I have discovered a peace and serenity I never thought possible – hard earned, freely given – through which I have found an inner strength to overcome the ongoing battle of addiction.
