Keystone Healthcare Partners

What Keystone Healthcare Partners does

Keystone Healthcare Partners is a privately held physician staffing and management services company founded in 1996 by Glenn Adams and Andrew Portelli. The company delivers emergency medicine, hospital medicine, and critical care physician staffing to acute care hospitals, with a deliberate focus on rural and community hospitals across the southeastern and eastern United States — including Mississippi, Alabama, Louisiana, Florida, New York, Pennsylvania, Kentucky, and Texas. Keystone operates from its Memphis, Tennessee headquarters, with additional corporate operations in Tampa, Florida, and a billing office in Plano, Texas (Keystone Medical Billing Services / KMBS). The company is 100% privately funded with no external institutional capital, and reports that 100% of its business and physician leaders are engaged shareholders, aligning operational incentives with long-term partnership outcomes. Average client tenure exceeds 10 years and physician retention is reported at 99%, with clinical staff retention at 99.8%.

Keystone's technology platform centers on Keystone Telehealth™, a proprietary telemedicine offering that spans pre-hospital (Tele-EMS, ER@Home), emergency medicine (Tele-Triage, Tele-ED), hospital medicine (Virtual Inpatient Rounding, Virtual Specialty Consults, Tele-ICU, Virtual Case Management), and post-discharge (Keystone Connect™ AI patient engagement) settings. Keystone Connect™ applies AI to real-time patient satisfaction and sentiment scoring via text outreach, with reported response rates two to three times traditional methods. In April 2026, Keystone added the DocAssistant AI documentation platform via partnership, providing HIPAA-compliant ambient scribing and CMS E&M-aligned billing optimization, with vendor-reported outcomes of an 85% reduction in charting time and 8% revenue increase per provider. The platform is supported by the Keystone Leadership Academy, an annual physician leadership development program, and a structured Startup Summit onboarding process for new contracts.

Keystone generates revenue through multi-year B2B contracts with hospitals using fee-for-service or hourly-rate staffing models, layered with managed-service practice management agreements that bundle back-office infrastructure (financial reporting, HR, credentialing, compliance, legal). The company operates five core revenue streams: physician staffing, practice management agreements, in-house revenue cycle management (KMBS, launched 2014), locum tenens staffing, and telehealth. GTM is exclusively direct enterprise sales targeting hospital CEOs, administrators, boards, and medical staff leadership through field-based relationship management, with concentrated focus on rural and critical access hospital segments where larger national competitors (Envision, TeamHealth, USACS) have reduced exposure.
