Dr. Bloom serves as chief medical officer for Adventist Health St. Helena and Adventist Health Clear Lake, leading clinical operations, quality and patient safety while aligning physician engagement and governance across both campuses. At St. Helena, he built new clinical infrastructure, including a vascular and limb salvage program, a regional cardiology call coverage model spanning five hospitals and a formal mortality review structure. His leadership helped reduce out-of-network transfers 40.2% year over year and cut avoidable hospital days by approximately 50%. He also played a key role in strengthening documentation and utilization processes that generated more than $6.7 million in overturned denials and additional billable charges in 2025. He drove a 20.8% improvement in sepsis SEP-1 compliance within six months and helped avoid multiple patient safety indicators through disciplined performance oversight. At Clear Lake, Dr. Bloom led the hospital to CMS 5-star quality status for the first time and reduced mortality by 37% in 2025, while securing at least $2.6 million in additional billable charges through clinical documentation improvement and overturned denials. He expanded access in a rural tri-county region by launching and growing service lines including pulmonology, rapid care, palliative care, orthopedics, nephrology telemedicine, neurology and pain medicine, contributing to sustained year-over-year earnings before interest, taxes, depreciation, and amortization performance. A board-certified emergency physician with deep public health and emergency preparedness experience, Dr. Bloom has also served as acting public health officer for Lake County, leading Covid-19 response and securing $3.7 million in public health funding.
