Why “Normal” Isn’t Enough

You may be doing everything “right” and still feel fatigued, unfocused, or stuck. Standard reference ranges are designed for broad populations—not for people who want to age with vitality. Our approach is built to help you reach optimal ranges and sustained performance.

Our Approach: Nurturing Your Whole Self

What Your Journey Includes

  • A Conversation That Truly Listens
    We begin with your story—your rhythms, sleep, stress, food, and what “better” means to you. Your goals shape every step we take.
  • Clarity Through Deeper Testing
    With 150+ advanced markers, we look past basic labs to what’s really happening—heart health, hormones, inflammation, nutrients, and gut balance—so you get clear, useful answers.
  • Your Personalized Wellness Plan
    Together we design a plan that fits your life: simple nutrition shifts, targeted supplements, sleep upgrades, stress tools, and habits you can actually keep.
  • Ongoing Partnership on the Journey
    Through our BeWell follow-ups, we check in, adjust what’s not working, and celebrate wins—so you feel seen, supported, and never on your own.
  • Insurance & Payment
    We’ll help you use insurance when possible, and we accept FSA/HSA to make care more accessible.

Finding Dr. Durrell has been such a relief for our family after months of frustration with traditional medicine. My niece was recently diagnosed with Hashimoto’s and has been experiencing completely debilitating symptoms that have been affecting her daily life, yet when she turned to her primary care doctor and even an endocrinologist for help, she was immediately dismissed with the words, “I can’t help you because your labs are normal.” It was devastating and unfortunately far too common to feel like no one was listening, let alone caring, about her actual symptoms and struggles. We considered many other functional doctors in Miami but ultimately chose Dr. Durrell because of his incredible reviews and his upfront, clear pricing. Making the jump from traditional medicine run through insurance to functional felt risky, but he has been completely transparent every step of the way and extremely generous with his time. We have even been able to use her insurance for some of the testing, which was unexpected and very helpful. At no point have we felt pressured to order unnecessary tests or buy supplements we didn’t need, which was one of our biggest fears in making this transition. From our very first interaction, the difference was night and day. His calm, caring demeanor instantly put us at ease, and he took the time to truly listen and explain things in a way that made sense. Even though we have just begun the process with him, the stress relief we have felt already is enormous. He truly has all 5-star reviews for a reason!! Honestly, I almost didn’t want to post a review just to selfishly gatekeep him, but he 100% deserves for everyone to know what an amazing doctor and human he is. This is what medicine should look like for everyone: patient-centered, compassionate, and deeply attentive. After so many disheartening experiences with physicians in Miami, simply having someone like Dr. Durrell in our corner has been an incredible blessing.
If you feel at the end of your rope with your health and are considering a functional or integrative approach, do yourself a favor and book a consultation with Dr. Durrell. Thank you, thank you, thank you, Dr. D!! <3

“Dr. Durrell Handwerger is the most knowledgeable and effective holistic practitioner I have ever met. From our first session, he asked detailed questions about my stress levels, sleep, family background, overall health, and diet. He wanted to fully understand my symptoms and interpret the tests I had done more than a year before with another doctor. I used to depend on a lot of coffee to get through the day, but that severely affected my sleep. I felt trapped in a cycle of exhaustion. After following Dr. Durrell’s recommendations, especially the supplements and small dietary adjustments, I noticed a huge change in just a few weeks. My energy is better than it has been in years and my anxiety is finally under control. Honestly, I never thought I could feel this good without caffeine. If you are suffering from fatigue, brain fog, or anxiety, I highly recommend Dr. Durrell. If you are forcing yourself to get through the day by convincing yourself that it’s normal to feel this way, it’s not. He has truly changed my life!”

“Dr. Durrell Handwerger helped me SOLVE digestion issues that I’ve had for 5 years! My thyroid is functioning better! He is also a true scientist who helped me gather all of the information I needed in order to understand my health. Dr. Handwerger has acted as an advocate, a consultant who tirelessly helps me understand my test results. This approach has also then empowered me to truly utilize my existing healthcare and team of doctors by guiding me and helping me develop questions to bring to my primary care doctor, my endocrinologist, and even my gynecologist. The supplements he recommends (and provides discounts to) are gentle and effective and MOST IMPORTANTLY treat the ROOT of my health problems. Then the symptoms just go away. I don’t need to treat symptoms anymore. Without Dr. Handwerger’s expertise and thorough testing, I would have had no idea how to understand, much less effectively work on, all of my health concerns. He is an advocate. He is a partner in my conscientious journey to excellent health. He is a return to hope that I will be able to address my health in a constructive way for the rest of my life. I’ve just turned 50 and my health is only improving.”

“It’s a blessing to work with a holistic health practitioner who genuinely takes the time to listen and who puts more emphasis on food as medicine rather than conventional pharmaceutical strategies. I also have to mention the comprehensive testing options that are available right from your home—the kits can be mailed directly to you! Especially for finding the root cause of Hashimoto’s thyroiditis, in my opinion these advanced tests are absolutely necessary (and reasonably priced) to continue to optimize your health when dealing with an autoimmune disease. South Florida Integrative Health Center gives you the ability to get involved in how your health improves; you’re part of the solution because it’s up to you to do the work. Thank you, Durrell, for all that you do for the South Florida community!”
