Sarah Zeigler, CADC III

Sarah Zeigler is a Certified Alcohol and Drug Counselor Level III and a Therapist Trainee. She is currently in her final year of studies to complete her M.A. in Counseling Psychology at the California Institute of Integral Studies.

“Dignity, agency, authenticity, and community are the core values guiding my recovery approach. I understand addiction as a disease that erodes our connection to these essential elements of humanity and recovery as a process of deep and intentional reconnection to the values that make life worth living. My dedication to these values has been cultivated over six years of experience working in addiction treatment, and they continue to inform my work as a Therapist Trainee at Summit Estate Recovery Center. As a therapist, I aim to facilitate collaborative experiences that empower individuals to connect with themselves and others authentically. I am passionate about providing trauma-informed, trauma-specific care focused on the cultivation of safety, self-efficacy, and self-compassion. I am also enthusiastic about helping clients integrate somatic, artistic, spiritual, and cultural practices into personally meaningful recovery and holistic wellness programs”.

Shelley E. McAlpine, M.A., LAADC

Shelley E. McAlpine, M.A.; LAADC; Lifetime Certified Health and Wellness Coach; Author of A Taste for Recovery

Shelly was born and raised in California. After graduating from high school, she attended
the University of Oregon, where she earned her Bachelor’s degree in Sociology. She then went on
to earn a Master’s degree from Rutgers University in New Jersey. While at Rutgers University
Shelley worked at the Rutgers Center for Alcohol Studies, where they were developing the Bio-
Psycho-Social model of addiction. Following graduate school, Shelley returned to California,
where she worked for local governments in Human Resources and occupied the positions of
Director, Chief Labor Negotiator, and Risk Manager. Throughout much of her adult life, Shelley
had her struggles with alcoholism and finally entered recovery. She has remained sober for a
number of years, during which time she launched a second career that she describes as her
purpose and her passion– an Alcohol and Drug Counselor, researcher, and author.

Shelley’s approach to recovery can best be described as “holistic.” Make
connections with others in recovery, eat a healthy diet, exercise, meditate, explore new interests
and activities, and turn a negative (active addiction) into a positive (active recovery), and you’ll
discover that recovery is an exciting adventure! It will be the greatest gift you ever give to
yourself and to those who love you!

At Summit, I am passionate about the mission and culture of the organization, and take pride in being part of a team that genuinely prioritizes client well-being.

I believe in meeting clients where they are and providing personalized support that helps lay a strong foundation for long-term recovery. Whether coordinating care with clinical staff, supporting direct care teams, or working one-on-one with clients, I believe in bringing both professionalism and heart to everything we do.

My passions include reading all kinds of genres, indoor gardening (I have over 150 houseplants!) & making sure that my fur kids are cared for and feel loved. I am an avid hiker and since moving to the Bay Area 6 years ago – I have hiked up and down the Northern California Coast from Norcal to the beautiful & awe inspiring PNW.

Lead Admissions Coordinator

Elyssa Mahoney

As an Admissions Coordinator, my primary role involves guiding individuals through the initial stages of treatment. I am deeply passionate about my work, as it enables me to be part of someone’s journey toward recovery and healing. I acknowledge the immense courage required to make that first phone call and the overwhelming emotions that can accompany the initial steps of seeking help. My job is to be there for you—to listen, provide support, and answer any questions you might have.

Admissions Coordinator

Tswyee Vue

I am an active member of the sober community and have had many lived and professional experiences with marginalized and “in need” communities. My work has involved communication and collaboration with individuals and groups from the LGBTQIA+ communities, justice-involved communities, homeless communities, communities whose individuals identify as immigrants, refugees, and migrants, as well as individuals experiencing SUD and/or mental health challenges. It is my passion to bridge the gaps between these communities and the help and services they may seek. I believe that all individuals deserve the chance to flourish and grow beyond their highest potential. In addition to my professional life, I enjoy recreational activities such as dance, singing, and beauty and fashion.

Group Facilitator - Rock to Recovery

Drew Mottinger, MA

“I love the quote, “Music can heal the wounds that medicine cannot touch.” I find this to be especially true in recovery, where music has proven to be an incredibly effective and sustainable tool in helping to calm anxiety, regulate mood, and improve impulse control. The early days of recovery can be unbelievably treacherous for addicts and alcoholics. Music can help us better navigate that early period of rebuilding and recalibrating. I have witnessed firsthand the healing power of music in a treatment setting, where clients who normally struggle to open up are able to do so through musical expression. By “forming a band” in Rock to Recovery, clients are able to work together on social skills, enhance communication, and increase self-esteem in a sober and creative environment.” 

Redeat Mengistie, EMT

Associate Therapist

Cassidy Hozer, ASW

Cassidy is a licensed Associate Therapist with a Master’s degree in Social Work, specializing in trauma recovery. With a professional background in healthcare, dual-diagnosis treatment, and care management, she brings a holistic and integrative approach to therapy. Cassidy empowers clients by fostering autonomy, self-confidence, and the tools needed to sustain lifelong sobriety. Her experience spans diverse populations, and she is deeply attuned to the systemic and generational challenges faced by marginalized communities. Through trauma-informed care, she helps clients navigate and heal from these complex adversities.

“I believe recovery begins when clients recognize their inherent worth and feel empowered to reclaim their lives. In therapy, I prioritize collaborative decision-making, ensuring clients’ beliefs, values, and motivations guide our work together. Using evidence-based techniques, I support clients in rediscovering their identity beyond addiction—equipping them with skills to live authentically and in alignment with their core values.

Addiction is a deeply stigmatized disease, often perpetuated by shame and isolation. It impacts every facet of a person’s life—straining relationships, self-perception, and future possibilities. In recovery, we honor the grief of what was lost while rebuilding trust, safety, and connection. Healing isn’t just about sobriety; it’s about restoring dignity, repairing relationships, and reclaiming a life anchored in self-respect.”

Counselor

Janine How Galliano

I am a Substance Abuse Counselor with over 23 years of experience in recovery services, born and raised in the Bay Area. I believe healing is a collaborative process rooted in honesty, accountability, and compassionate care without judgment. Creative expression is central to my philosophy, as it opens pathways to insight, resilience, and lasting change.

My professional foundation began at Sequoia Treatment Center in Redwood City, where I completed my supervised practicum in Substance Use Disorder treatment. My counseling style is direct, grounded, and encouraging, shaped by both lived experience and years of clinical work.

At Summit Estate, I facilitate psychoeducational and process-oriented Substance Use Disorder (SUD) groups focused on relapse prevention, behavioral awareness, coping strategies, and recovery skill development. Through guided writing, experiential exercises, and reflective dialogue, I help clients strengthen self-awareness, process emotions, and engage fully in their recovery.

I serve as a 12-Step Facilitator at Hillcrest Juvenile Hall in San Mateo County and as an H&I Volunteer facilitating recovery meetings for veterans at the VA Palo Alto Health Care System. I hold a Bachelor of Arts in French Language Education from La Sorbonne in Paris and am Director Qualified in Early Childhood Education (ECE). I completed Substance Abuse Counseling coursework through Penn Foster Career School and maintain CPR and First Aid certification.
