Attest Health Care Advisors

What Attest Health Care Advisors does

Attest Health Care Advisors, LLC is an independent, privately held professional services firm founded in 1997 as the healthcare payer consulting division of a Big Five accounting firm and divested as a standalone LLC in 2006 in response to Sarbanes-Oxley regulations. Headquartered in San Antonio, Texas, the company operates as a fully virtual organization with all personnel working from home offices secured via a virtual desktop environment with two-factor authentication and a ShareFile-based secure file transfer portal; it has maintained HITRUST certification continuously since first achieving it in 2016.

The firm delivers a concentrated portfolio of non-financial healthcare quality and compliance audit services across five product lines: NCQA-licensed HEDIS® audits and consulting (including HEDIS Compliance Audit, mock audits, supplemental data source audits, and state-based programs such as CA AMP, NYS QARR, and FL ACHA), CMS Medicare Part C & D Data Validation audits alongside Independent Auditor Validation (IAV) and Compliance Program Effectiveness (CPE) audits, URAC Pharmacy Data Validation, HHS Risk Adjustment Data Validation (RADV), and custom Data Consulting covering system migrations and new data source integrations. The company is the largest NCQA-licensed HEDIS audit organization, the sole validator for URAC Pharmacy Data Validation since the program's inception (which it co-developed in 2015), and audited over 50% of all HEDIS submissions and 25%+ of Medicare Part C & D contracts nationwide in 2025. Operationally, the firm employs 19 Certified HEDIS Compliance Auditors (CHCAs) on staff, supported by an in-house IAV tool and 24 dedicated full-time validators for URAC work.

Commercially, Attest operates a sales-led, direct-engagement model serving health plans, pharmacy organizations, hospital systems, provider groups, and data vendors on a national basis in the United States. Revenue is generated through fixed-fee professional services engagements, and the firm has not missed a filing deadline on any audit since 1997. Client retention is reinforced through an annual HEDIS® Client Conference (entering its 20th anniversary in Las Vegas in October 2026), and go-to-market relies on website inquiry forms and direct sales with no self-serve, channel, or product-led motion. The company is led by six Principals functioning as C-suite executives: Laura Hart (CEO), Glen Braden (CFO/CIO), Christy Patterson (COO), Kevin Gregory (Chief People Officer), Michael Williams (Chief Quality Officer), and Melissa Sheesley.
