Lewisville, TX · Est. with Purpose

We Started Doctor Slim Because Weight Loss Alone Was Never Enough

Most clinics hand you a prescription and wish you luck. We built something different — a place where medical weight loss, body rejuvenation, and long-term wellness work together under one roof, with real people guiding you every step of the way.
Our Mission

More Than a Weight Loss Clinic. A Long-Term Wellness Partner.

At Doctor Slim Med Spa, we believe that losing weight is only the beginning. The real transformation happens when your outside finally catches up with your inside — when loose skin is addressed, muscle is preserved, collagen is restored, and your body is treated as the complete, interconnected system it actually is.

That belief is what separates us from every other weight loss clinic in Lewisville, TX. We don’t just manage your medication. We invest in your outcome. From your first consultation to your last milestone, our coaches, medical team, and advanced technology are working together on one goal: making sure your results last, look great, and feel even better.

We call it longevity-focused wellness — and it’s the foundation of everything we do.

We serve patients across Lewisville, Flower Mound, Highland Village, Lake Dallas, and all of DFW North — bringing physician-supervised care and advanced rejuvenation technology to a community that deserves both.

Our Approach

The Doctor Slim Difference — Why Our Patients Stay and Thrive

We built our program around one simple truth: real results require treating the whole person, not just the number on a scale.

Medically Supervised From Day One

Every weight loss protocol at Doctor Slim is prescribed and overseen by a licensed medical professional. Our on-site medical director brings clinical expertise and an expanding suite of therapies — including peptides — to ensure your plan is safe, evidence-based, and built for your biology.

Longevity Over Quick Fixes

We focus on what lasts. That means addressing the side effects of weight loss that most clinics ignore — loose skin, collagen depletion, and muscle loss — with advanced RF skin tightening, red light therapy, and peptide protocols that protect your results long-term.

Personalized Coaching at Every Stage

You are not a file number. Your dedicated Doctor Slim coach is with you from your first consultation to your final milestone — adjusting your plan, answering your questions, and keeping you accountable through every stage of your journey.

Advanced Technology Under One Roof

From the 360° body scan that gives you a measurable baseline on day one, to the Pelvic Chair, shockwave therapy, stem cell injections, and vibration plate — we bring the tools that most clinics don’t even offer, all in one convenient Lewisville location.

Accessible Wellness

We believe advanced care should be accessible. That’s why we offer flexible payment options including private pay, FSA/HSA with a qualifying referral, and CareCredit financing through our affiliated physician — so your goals don’t have to wait.
