Zachary Clark, formerly of Uber Health, steps into the role of Chief Operating Officer, bringing experience in navigating complex Medicare Advantage ecosystems. He joins Dr. Joshua Sclar, who will oversee health strategy and product development, and Logan Hasson, a Cityblock Health founding team member tasked with scaling the CareScape technology platform. Addison Giannini rounds out the expansion as Executive Vice President of Health Plans, focusing on the company’s national footprint.

These hires arrive as payers increasingly embrace nutrition as a primary clinical tool. A June 2026 study published in Nature Medicine underscores this shift, reporting that Medicaid recipients who received medically tailored meals saw hospitalizations drop by 31%. By combining meal delivery with registered dietitian support and closed-loop navigation, ModifyHealth aims to convert these clinical outcomes into standard practice for health plans managing complex, high-utilization populations.
