Sollis Health Appoints Katy Marshall as Chief Growth Officer to Lead Marketing, Sales, and Product Strategy

The leading concierge medical provider taps seasoned expert with track record of scaling consumer and healthcare brands to steer the company's next phase of growth into new markets.

NEW YORK, April 14, 2025 /PRNewswire/ -- Sollis Health, the first concierge medicine provider to offer its members 24/7 access to ER-level diagnostics and capabilities, is pleased to announce the appointment of Katy Marshall as Chief Growth Officer, effective today. With 15 years of experience scaling high-growth consumer and healthcare brands, Katy will lead Sollis Health's marketing, sales, and product strategies to further expand the company's personalized, high-touch healthcare services.

Katy's background includes a number of leadership roles, most recently serving as Chief Operating Officer of Thesis where she drove digital innovation and channel expansion, contributing to the company's recognition by the Financial Times as one of America's fastest-growing companies. At Calibrate, as Chief Marketing Officer, she was instrumental in scaling revenue from $1M to $100M and forging strategic partnerships with major corporations. Her earlier experience at Kraft Heinz involved managing iconic brands and co-founding the Springboard incubator, which led to substantial revenue growth and notable marketing successes. Katy started her career at BCG and holds an MBA from Harvard Business School.

"Katy is a powerhouse growth leader who understands how to build trusted, beloved brands while driving operational scale," said Brad Olson, CEO of Sollis Health. "She has consistently delivered results at the intersection of health, technology, and consumer experience, and I'm thrilled to welcome her to the executive team as we enter this next stage of growth."

In her new role, Katy will focus on growing membership by continuing to build Sollis Health's brand, expanding partnerships with medical providers and like-minded consumer brands, and launching innovative new products and services. Her appointment signals the company's commitment to building a category-defining healthcare experience at scale—one that puts members first and sets a new standard for concierge medicine.

"What drew me to Sollis is the opportunity to reimagine what healthcare can feel like—personal, immediate, and completely centered around the patient," said Katy Marshall. "Throughout my career, I've been inspired by category-defining businesses. I'm excited to help scale Sollis's unique model and continue delivering an experience that puts our members' needs first."

The appointment comes as Sollis Health continues to scale nationally with centers in New York, the Hamptons, Los Angeles, San Francisco, and South Florida—and is further expanding its Northern California presence with a new Palo Alto location opening next month. The company provides members with 24/7 access to emergency-trained physicians, advanced diagnostics, and concierge-level care coordination—eliminating traditional barriers to care and delivering peace of mind when it matters most.

Sollis Health also recently launched a nationwide Family membership tier, along with an elevated Family+ membership in Los Angeles—marking the first time families can access both world-class pediatric care and 24/7 emergency medical services under one membership. This comprehensive offering redefines what it means to deliver seamless, full-family care.
