Oak Street Health is a nationwide healthcare provider whose mission is affordable and accessible primary care for moderate-to-low-income senior adults. Given its target demographic, Oak Street Health focuses on making its clinics places people want to visit, with large community areas that feel pleasant and relaxing. To optimize layouts and improve efficiency, CosciaMoos Architecture was selected to helm the company’s national expansion. Drawing on its healthcare expertise, CosciaMoos paid special attention to enhancing the patient experience in each clinic’s communal spaces while also improving staff flow and refining the brand manual for the owner’s project managers and other vendors. As Oak Street Health’s rapid growth demanded increased speed to market, CosciaMoos completely overhauled the project management approach while also developing new standards replicable in any state. The firm built partnerships with local consultants to get practical insight and helped Oak Street Health build relationships with manufacturers to leverage buying power and dependability. Oak Steet Health has built over 150 clinics across 20 states in the last 4 years.
