Meet the Town Square Health Leadership Team
Our leadership team has come together with a singular vision: Create the gold standard for how we experience health care in the United States.
We asked our leaders to share how they feel about being part of the visionary team at Town Square Health.
David Buchanan, MD, MS
Chief Executive Officer
I’m proud that we’ve launched Town Square Health — a new kind of healthcare company delivering Better Healthcare, Built Around You. Building this has been a labor of passion and purpose. I couldn’t be more excited about the visionary team members who have joined to launch this company.
Marshall Glanzer
Chief Technology Officer
I'm excited to be leading the technology team at Town Square Health! Technology has the power to transform healthcare — but only if it enhances connection, not complexity. At Town Square Health, we’re building tech that supports our care teams, simplifies patient experiences, and enables smarter, more seamless coordination across specialties.
Lauren Ranalli, MPH
Vice President, Community and Patient Engagement
Improving access to healthcare has been the driving force of my career. I’m thrilled to focus on building trusted relationships beyond the clinic walls by engaging directly with community leaders, developing local partnerships, listening to patient needs, and creating opportunities to bring healthcare closer to the people who need it most.
Ellen Wager, MPH, MS
Vice President, Operations
It is such an honor to lead the long-term and day-to-day processes that will result in opening new health centers for Medicare patients. At Town Square Health, we’re focused on aligning systems around people — not the other way around. That means smarter workflows, stronger support for clinicians, and simpler access for patients.
Fiona Wagner, MHA
Vice President, Provider Strategy and Population Health
As someone passionate about scaling thoughtful, patient-centered models, I’m energized to be part of a team transforming how value-based care is delivered — from the ground up. I love that we’re building care teams that are collaborative, data-informed, and rooted in deep relationships — because when we truly know our patients, we can change lives for the better.
