Cornerstone Dental Specialties

What Cornerstone Dental Specialties does

Cornerstone Dental Specialties is a privately held, dentist-owned Dental Services Organization (DSO) headquartered in Irvine, California, focused on endodontic and expanding specialty dental care. Founded circa 2000 by practicing endodontists and led today by CEO Thomas von Sydow and Founder/President Dr. Hamid R. Abedi, the company operates as a professionally managed platform that signs on endodontists as associate owners while acquiring existing endodontic practices under all-cash deal structures. Its affiliated clinical base spans more than 40 endodontists across 10+ U.S. states (Arizona, California, Illinois, Minnesota, Missouri, Ohio, Tennessee, Texas, Utah and others), positioning the company as one of the largest endodontic groups in the country with over 1 million cumulative root canal procedures performed.

The Cornerstone Success Platform bundles non-clinical administrative services (billing, HR, IT, marketing, payroll, supply/equipment procurement) with proprietary clinical assets developed and refined over 15+ years, including the GEMS endodontic method and product line (launched 2022), a custom mobile application (Connect Team) for scheduling, financials, and supply ordering, and the Cornerstone Training Institute in Irvine offering continuing education and a Fellowship Program. Revenue is generated through three streams: managed services for affiliated endodontists, practice acquisition transactions (cash-based equity transitions), and professional support services.

Customer acquisition is dual-sided: endodontists are recruited through the careers page, industry conferences (AAE, Dykema), and direct partnership outreach led by Phil Roth, while general-dentist referrals are cultivated via collaborative treatment planning. The company explicitly states it is not bank- or PE-owned, with ownership and board control held by practicing endodontists, and was recognized at the 2025 Orange County Business Journal CFO of the Year Awards for financial leadership under CFO Nick N. Khalili.
