Dr. Daniel Klein
Owner, Chiropractor
With over 30 years of experience, Dr. Daniel Klein has helped thousands of patients overcome pain, recover from injury, and return to the activities they love to do, need to do, or want to do—whether that’s playing golf or tennis, practicing yoga, working out, running, gardening, crafting, hiking, or simply getting through the workday comfortably. He believes every patient deserves a clear, personalized path to healing—so they can stay healthy and fully engaged in what matters most, from family time and travel to professional focus and everyday enjoyment.
Dr. Klein takes a whole-body approach to chiropractic care, addressing not just symptoms but the root causes of pain and dysfunction. He blends gentle, evidence-based techniques with decades of clinical experience to create safe, effective, and individualized treatment plans.
To accelerate healing and improve outcomes, Dr. Klein incorporates some of the most advanced technologies in chiropractic care today—including SoftWave Tissue Regeneration Therapy (TRT) and Class 4 therapeutic lasers. These non-invasive tools help reduce inflammation, increase circulation, and support faster recovery—so patients can return more quickly to the activities they love to do, need to do, or want to do.
Patients describe Dr. Klein as warm, approachable, and easy to talk to. He takes the time to listen, answer questions, and explain each step of care in simple, clear terms—so you always feel informed, confident, and in control of your health journey.
Outside the clinic, Dr. Klein lives the active, healthy lifestyle he encourages in his patients. He has completed 14 marathons and 16 full-distance Ironman triathlons, and firmly believes in the power of movement, mindset, and nutrition. His philosophy is simple: move well, think well, eat well.
“It’s about more than just feeling better—it’s about getting you back to living fully.”

Hoy, después de más de un mes de despertarme con dolores que superaban la escala de 10, hoy por fin me desperté con un dolor mínimo que me permitió dormir toda la noche. Además de explicarme el origen de mis dolores, también me dijeron la solución a mi problema que lleva más de 5 años. Además, me encontré con un equipo de profesionales increíble y lo mejor es que hablan en mi idioma, lo que me hace sentir muy cómoda y con una traducción perfecta.
