David Izquierdo
Business Manager
I'm David Izquierdo, Manager of Biziondo. I'm not a doctor, but I know what it's like to live with back pain.
I've been treating spinal problems for over 20 years, training in axial decompression and cervical biomechanics. But beyond the theory, what truly allows me to understand our patients is having been through the same thing.
I've experienced firsthand what it means to go from doctor to doctor without clear answers, feeling like the healthcare system and health insurance companies are putting up obstacles instead of solutions. That's why at Biziondo, we work differently: we seek real, effective, and straightforward treatments.
My philosophy is simple: "If it were my column, what would I do?" That's the question that guides every decision.
If you're looking for answers, you'll find them here.
Your spine, your well-being. We'll help.
Every day you postpone your recovery is a day you lose quality of life. Don't wait any longer.
