Meet the Doc


  • Founder, Owner and Head Chiropractic Physician

I’m Dr. Kristi Black, and I help people move better, feel better, and get back to doing the things they love—without relying on painkillers, surgeries, or quick fixes.

I became a chiropractor because I’ve seen firsthand how powerful natural, hands-on care can be—especially when it’s focused on the nervous system, not just the symptoms. My goal with every patient is to listen first, then build a care plan that helps their body heal from the inside out.

Before chiropractic, I spent years as a volleyball coach and certified personal trainer, which gave me a deep understanding of movement, posture, and how the mind and body work together. I bring that same energy into every visit—whether you’re recovering from an injury, dealing with chronic tension, or just want to feel stronger and more aligned.

I hold a Bachelor’s degree in Psychological Sciences from Cal State San Marcos (magna cum laude) and earned my Doctor of Chiropractic degree from Logan University in St. Louis, Missouri.

At BlackSphere Chiropractic, you can expect personalized care, cutting-edge tools, and a healing space where you’re heard, supported, and empowered.
