Our STAFF

I’m Dr. Tim Martin (aka Medicine Man) — Medical Director here at AARS with my own practice in Abilene as well. I’m a physician who believes deeply in treating the whole person, not just the symptoms. Substance use disorder is complex, layered, and deeply human — and I approach every patient with that understanding. My goal is to provide care that’s both evidence-based and heart-centered.

I specialize in opioid dependency and have spent years working closely with individuals navigating recovery. I don’t do fluff, and I don’t believe in one-size-fits-all treatment. What I do believe in is honesty, trust, and treating people with the dignity they deserve — no matter where they are in their journey.

I bring a no-nonsense approach to medicine, but also a great deal of compassion (and if you’ve spent personal time with me, you’ve probably also caught onto my humor). I care about each patient as an individual, and I take pride in offering treatment that respects both their biology and their story.

Outside of the clinic, I find peace in nature and joy in spending time with my children — both are grounding forces in a world that often moves too fast.

At AARS, I’m proud to be part of a team that leads with integrity, humor, and an unwavering belief in recovery. This work matters, and I’m honored to do it every day.

I’m Margaret Gray (aka MG the OG)— nurse, truth-teller, and occasional master of the well-timed deadpan. I’ve been in the nursing field for decades, working in just about every setting you can imagine. What’s never changed is my passion for helping people — especially those navigating opioid use disorder. This work matters to me deeply, and I bring both clinical experience and real-life understanding into every room I walk into.

My life’s been a wild ride — filled with incredible friendships, a couple of romantic relationships (good, bad, and ugly), kids, grandkids, some hard seasons, and a whole lot of laughter. I don’t shy away from the messy parts of life — I’ve lived them. And that’s exactly why I love this work. I see our patients not as problems to fix, but as people worth showing up for.

I’ve got a reputation around here for keeping a straight face just long enough to make you think you're in trouble... and then cracking a joke right when you least expect it. But underneath the sarcasm, I’ll always tell you the truth — especially if you need to hear it. I don’t do fake, and I don’t do surface-level. What I do is show up with honesty, loyalty, and a whole lot of support.

Outside of AARS, my greatest joy is spending time with my grandkids — they keep me grounded, laughing, and busy in the best way. Being their grandma is the role of a lifetime, and I take it just as seriously as I take nursing (okay, maybe with a few more hugs and snacks involved).

At the end of the day, I’m here because I believe in people. I believe in second chances. And I believe in bringing both skill and heart to every patient I meet.

 I’m Sandra Flores, LCDC  (aka The Bossy One)— and I’ve been working in methadone treatment for over 30 years. I believe recovery is a daily commitment, and I’m all about encouraging people to take responsibility for their own healing — with support, honesty, and a little tough love when it’s needed.

I’m a person in long-term recovery, and I share my story because I know how powerful it is to hear, “you’re not alone.” I’m direct, sometimes blunt, but always coming from a place of care. As I often say, “I give a shit if you live or die,” and I mean that with my whole heart. I’m not here to do the work for anyone, and I have no problem saying, “I’m not going to do that,” — because recovery only works when you do.

When I’m not at the clinic, you’ll find me surrounded by my real bosses: my four pugs — Arlo, Bain, Dolly, and Sadie. I recently lost my longtime sidekick, Cali, and she’ll always have a piece of my heart. I proudly claim my title as “pug mom” and, honestly, I love dogs more than humans most days (no offense — well, maybe a little).

I visit my kids and grandkids as often as I can, and they always manage to make me laugh, shake my head, or both. I bring a mix of sass, heart, and just the right amount of cantankerous charm to this work — and if you’re ready to get real, I’m ready to walk with you.

Hi, I’m Jasmine Majkowski, EdD (aka Dr. Jazz and HBIC - and probably other names they don't tell me about!) — a passionate advocate for recovery, a fierce lover of my beautifully chaotic family (shoutout to my incredible Co-Coordinator of Chaos and Chief of my Heart, Brooks, and our adventurous, brilliant, and wild-hearted sons), and a globe-trotting foodie with an unapologetic addiction to bold flavors and even bolder stories.

With a background rooted in education, leadership, and healthcare, I bring sharp insight, heart-centered leadership, and just the right amount of sarcasm and wit to the world of healing and transformation. Recovery isn’t just something I believe in — it’s something I fervently protect and for which I advocate strongly.

 Whether it’s supporting individuals through life’s most raw and real moments or building programs that actually work (because mediocre just isn’t in my vocabulary), I’m here for the gritty, the growth, and the grace.

When I’m not knee-deep in the magic of helping people reclaim their lives on the daily, anymore, you’ll find me passport-in-hand, chasing the next unforgettable journey, meeting new friends, constantly brainstorming and changing the impact AARS and I have on the world, or creating beautiful memories with all my boys.

This work is very personal. One gone is one too many, and one saved is never enough.  This work is sacred. And I’m proud to be doing it.  My best friend, JJ, died of a heroin overdose in 2004.  Why he didn't seek treatment died with him.  I decided in 2020 that his life would not go unnoticed.  

The shame and stigma associated with "recovery" existed in 2004 when JJ died and still exist in today, EXCEPT at ARS- Abilene.  

I'm here because of God, and I'm here FOR ALL WHO SEEK HELP.  No judgment ever.  Nobody walks through these doors on a winning streak, but by my AMAZING STAFF'S perseverance, understanding, and love, and God's grace, we pray they walk out with the tools that will lead them to the biggest win of their lives: living their best life, free of substances.

BEST AND BLESSINGS! XXXOX

Reach me at our clinic at x3.

I’m Terri Kreizenbeck (aka The Talker)— the first face you’ll see when you walk through our doors. I serve as the medical practice manager and nurse here, and I move between the front and back of the clinic depending on what the day (or moment!) calls for. Around here, flexibility is key — and I’ve got plenty of it.

I’m incredibly proud of my sons, Cameron and Colton, and share a special bond with my daughter, Ashleigh, and my sweet granddaughter, Mavis. Family is everything to me — and that includes my fur-baby, Miss Biscuit, who you might catch keeping watch from the front window. She’s convinced she runs the place… and honestly, she might not be wrong.

I’ve always got a story to share, a laugh to offer, and a readiness for whatever adventure comes next — whether that’s in the clinic or out in the wild world.  I'm a mix of sass, class, and smart-ass.  Life’s too short to take too seriously, and I believe in bringing a little humor to the chaos whenever I can.

I’m Jay Powell (aka The Calm One)— LCDC-Intern and probably the quietest presence in the office (but don’t let that fool you — I’ve got a good sense of humor and a lot of heart). I show up each day with a deep belief in recovery — not just because it’s the work I do, but because it’s the life I live. As someone in long-term recovery, I know healing doesn’t look the same for everyone. I encourage people to find their own path, but I also believe strongly in the power of group support, private counseling, and medication as tools that can help people move forward.

I’m currently pursuing my Master's Degree and continuing to grow both professionally and personally. I bring steady consistency, lived experience, and a whole lot of compassion to the table.

After work, you’ll usually find me at the gym — it’s my way of decompressing, staying centered, and taking care of myself so I can continue showing up for others. I’m also a proud father of two adult sons, and I carry that same quiet commitment to fatherhood into the way I support our patients: with calm, consistency, and real care.

AARS has been a meaningful part of my own journey, and I’m grateful to be part of a team that values authenticity, growth, and the transformative power of recovery — one day at a time.

 I’m Debra Gamboa — counselor, truth-teller, (AKA  Pocket-Sized Powerhouse). I may be barely five feet tall, but I bring enough grit, life experience, and straight-up attitude to fill any room I walk into.

Before working in recovery, I spent time working in the prison system and other recovery situations, where I developed a sharp understanding of human behavior, resilience, and accountability. That environment teaches you quickly: people don’t change through comfort — they change through honesty. That mindset still drives my work today.

I’ve become known as the one who “makes everybody cry,” but not because I’m harsh. Growth is uncomfortable. Healing is emotional. And when people finally face the truth about what’s holding them back, things tend to get real. My job isn’t to sugarcoat — it’s to challenge, support, and help people recognize their own strength.

At AARS, I meet patients with authenticity, humor, and respect. Recovery is raw and deeply personal, and I believe compassion and accountability are most powerful when they work together.

Outside of the clinic, my most important role is being a mom — a responsibility that shapes my perspective, my empathy, and my passion for helping others build better lives.

I’m unapologetically myself — tattoos, edge, and all — and I believe our past experiences can refine us without defining our limits.

At the end of the day, I care fiercely about the people I work with. Even when I push them. Especially when I push them. Because real change rarely happens in the easy moments — it happens when someone decides to step up and do the work.

I’m Alexandrea “Alex” Gonzales — and I never know what my job description will be (aka The Rockstar).  I am the proud mama to my son Gregory, honorary bonus mom to Ivy, and loyal to my best friend Chase. I’m also a woman in recovery who knows exactly what it means to rebuild a life — brick by brick, and sometimes with nothing but grit and faith.

If there’s an event to pull off, I’m your girl. Need a speaker? A resource? A whole team rallied in 24 hours or less? I’ve got you. I know the recovery community inside and out — not just because I’ve walked this road myself, but because I live and breathe it every single day. This work is personal, and it’s sacred. I’ll never ask someone to do something I haven’t done myself — but I will hold them to the fire if I know they’ve got more in them. We rise together, or we don’t rise at all.

Give me a clipboard and a cause, and watch me move. I thrive in chaos, shine in pressure, and never back down from a challenge. I don’t need credit — just give me the assignment and step aside. Whether it’s coordinating a community event, rallying volunteers, or connecting someone to the right service at just the right moment, I handle it with heart and hustle.

Off the clock, my world revolves around  my family, laughing every chance I get, and asking Chase to build whatever my brain whips up at the moment.

I believe in radical grace, fierce accountability, and always leaving the door open for the next person coming in from the dark. Recovery gave me my life back — now I get to help others find theirs. And trust me, if there’s a way to make something happen?

I’ll find it. I’ll fix it. I’ll do it.

Because that’s what rockstars do.
