I help healthcare organizations transform operations, analyze complex data, and conduct rigorous research and evaluation to inform practical decisions. My work sits at the intersection of healthcare leadership, analytics, and health services research. I bring more than 30 years of experience across hospital and ambulatory operations, health information technology, quality improvement, data infrastructure, and organizational transformation. I have served as interim COO and CIO and have advised rural hospitals, safety-net organizations, clinics, and multi-site systems. My experience includes leading major EHR and digital transformation initiatives, building enterprise analytics and reporting capabilities, improving revenue cycle performance, redesigning clinical and administrative workflows, and translating findings into executive-level recommendations. Selected results include reducing emergency department length of stay from 300 to 100 minutes, improving a CMS Star Rating from 3.0 to 4.5, reducing accounts receivable days from 120 to 52.5, and generating $1 million in annual savings through infrastructure modernization. My primary service areas include: HEALTHCARE TRANSFORMATION • Operational and organizational assessments • Digital transformation and EHR optimization • Clinical, administrative, and revenue cycle workflow redesign • Quality improvement and performance measurement • Data governance, reporting infrastructure, and interoperability • Strategic planning, implementation roadmaps, and executive decision support • Interim and advisory COO/CIO leadership HEALTHCARE DATA ANALYTICS • Medicare and Medicaid claims analysis • EHR, hospital discharge, enrollment, survey, financial, and operational data • Longitudinal cohort construction, eligibility logic, and data linkage • Descriptive analysis, regression modeling, trend analysis, and predictive analytics • Geographic and county-level analysis • Quality, access, utilization, spending, and performance measurement • Reproducible workflows using R, SAS, Python, and SQL • Executive dashboards, publication-ready tables, and technical reporting RESEARCH AND EVALUATION • Research questions, protocols, and statistical analysis plans • Program, policy, implementation, and mixed-methods evaluation • Survey design, interview guides, qualitative coding, and evidence integration • Literature reviews, scoping reviews, and evidence synthesis • Medicare, Medicaid, rural health, access, value-based payment, and health policy research • IRB materials, manuscripts, technical reports, and grant-related research products • Independent methodological review and evaluation planning I hold an MPH and am a PhD student in Population Health, specializing in Health Services Research and Policy. My current research examines rural health systems, Medicare payment reform, healthcare spending, access to care, delivery-system capacity, and geographic variation in healthcare outcomes. I also serve as a peer and proposal reviewer in health services research, public health, healthcare quality, and health information technology. Clients receive more than an analysis or a report. They receive a structured approach that integrates the data, methodology, operational environment, policy context, and implementation constraints. My goal is to produce work that is methodologically defensible, clearly communicated, and usable by healthcare leaders, researchers, and policymakers.
