Port of Subs® Names Mandy Miller as 19th Regional Developer, Expanding into San Diego

April 22, 2026 // FranchisePR.com // Denver, CO. – Port of Subs continues to scale its national franchise platform with the appointment of Mandy Miller as its 19th Regional Developer, marking a key milestone as the brand nears its goal of establishing its first 20 Regional Developers nationwide. Miller’s territory spans Southern San Diego, including Coronado, Chula Vista, and surrounding communities, with plans to develop a minimum of 10 locations and expand into additional territories over time.

Miller brings more than a decade of franchising and development experience to her new role, having previously helped scale a wellness franchise from one location to more than 50 units nationwide. Her background spans franchise sales, real estate, site development, and construction; expertise that will be used to establish and grow the Port of Subs footprint in the region with Jim Rowe, her partner. As a fourth-generation resident of the area, Miller has deep roots in the community. The duo will lead franchise sales and support for the assigned territory.

“We were immediately drawn to the strength of the Port of Subs model and the team behind it, but what really stood out was the opportunity to build something meaningful in our own community,” said Miller. “San Diego represents a unique white space for the brand, and we see tremendous opportunity to thoughtfully grow the footprint while establishing a strong, locally rooted franchise network across the region.”

The appointment emphasizes Port of Subs’ broader strategy to expand with experienced Regional Developers who can build, scale, and support local franchise networks.

The unique model offers Regional Developers the opportunity to act as self-sufficient local extensions of the brand-driving growth in the region while building on an established foundation. With over 50 years in business, a strong leadership team, and the backing of franchise growth engine Area 15 Ventures, both Regional Developers and franchisees benefit from experienced operational, marketing, and technology support and a proven pathway to scalable growth.

Within the role, Miller’s responsibilities include franchise sales and long-term operational support, ensuring consistency, brand compliance, and sustained performance across the market.

“Mandy and Jim bring a rare combination of development expertise and proven franchise leadership, having successfully scaled a brand from a single location to more than 50 units,” said Healey Mendicino, CEO and President of Port of Subs. “Their experience across real estate, construction, and franchise growth, as well as their long history in the community, makes them exceptionally well-positioned to build and support a high-performing network in San Diego as we continue to expand.”
