About PracticeHalo: Built by Practitioners

10+ Years in Regenerative Medicine. One EMR Built From It. We didn’t design PracticeHalo from the outside—we built it while running our own clinics.

Our Story

A Decade of Real-World Testing

For over a decade, our team has operated R3 Stem Cell — one of the LARGEST regenerative medicine networks in the USA and Mexico. We have treated more than 27,000 patients across multiple locations.

Along the way, we tried every tool out there. Separate CRMs. Standalone schedulers. Spreadsheets to fill the gaps. Nothing fit. Regenerative clinics work differently. Providers rotate locations. Pricing changes by protocol. Leads go cold in hours, not weeks.

No EMR on the market handled that. So we built PracticeHalo. Every feature comes from a real problem we hit while running our own clinics.

Our Mission

EMR Built for the Way You Work

Most EMRs were made for insurance-based primary care. One provider. One location. One billing model. That is not how regenerative medicine works.

PracticeHalo gives clinic owners one EMR for leads, scheduling, patient records, billing, and reporting. No workarounds. No duct-taped tools. When operations run clean, you focus on patients.

Meet the Founders

From the clinic floor to your screen.

Dr. David Greene (MD, PhD, MBA)

Founder

Dr. Greene started R3 Stem Cell over a decade ago and grew it into one of the largest regenerative medicine networks in North America. After treating 27,000+ patients, he saw every gap that standard EMRs leave open.

Zulfikar Ali

Co-Founder

Zulfikar has worked inside the R3 network for years. He knows what breaks when clinics try to scale with the wrong tools. He turned those pain points into the workflows and architecture behind PracticeHalo.

Samantha Brechner, BA, MBA

Co-Founder

Sam leads growth and partner success. She helped expand the R3 Alliance to 150+ clinic partners and makes sure PracticeHalo keeps up with what clinic owners actually need as they grow.
