AdventHealth plans to expand its presence in Lake Mary Health Park with new medical office

AdventHealth's Lake Mary office looks similar to its planned 36,000-square-foot medical office building on S.R. 50 in Clermont.

Altamonte Springs-based AdventHealth is expanding its footprint in Lake Mary.

The non-profit healthcare system is working to secure building permits for a planned 58,270-square-foot medical office building next to its emergency room hospital at 950 Rinehart Road.


Plans show a 3-story commercial building designed by HuntonBrady Architects with large exterior glass features facing Rinehart Road and a surface parking lot with up to 245 parking spaces behind the facility.

Kimley-Horn & Associates is the civil engineer.


In total, AdventHealth owns about 11.5 acres between I-4 and Rinehart Road. The property is part of a larger assemblage of land AdventHealth bought in 2013 for $6 million.

The new medical office building is set to rise on about 3.5 acres of land, while the 18,700-square-foot emergency building was built in 2016 on about 1.7 acres. Most of the remaining land will be used for parking.

A conceptual elevation submitted to the city shows the hospital will feature offices for lab, physical therapy, imaging and physician practices. Plans also mention a cafe being built within the facility.

Lake Mary’s planning and zoning commission approved its proposed site plan late last month.

The project is located along Rinehart Road where other hospitals and medical offices are being built.

In 2019, Orlando Health opened a two-story, 40,000-square-foot emergency department and 3-story, 60,000-square-foot medical office about a mile south. The plans are part of the health care system’s Reinhart Road campus, which will include a 6-story, 134-bed patient tower as part of a future phase.

The Orlando Health campus sits within the 150-acre Lake Mary Wellness and Technology Park, where Sonata Senior Living and capital partner, Berkshire Residential Investments, recently broke ground on a $62 million, 193-unit assisted living facility.

Representatives with AdventHealth did not immediately respond to requests for comment.


The faith-based health system is one of the largest in Florida. Its Central Florida division has more than 20 hospitals and ERs across seven counties.

In Clermont, AdventHealth is currently building a 36,000-square-foot medical office building and a 19,000-square-foot emergency room at the intersection of S.R. 50 and Citrus Tower Boulevard. The health park is slated to open in October.

The Clermont facility will be AdventHealth’s seventh freestanding emergency room/medical office complex in Central Florida. It also recently opened freestanding emergency departments in Kissimmee and near Disney, along Palm Parkway.

In 2019, AdventHealth paid $9.6 million for a freestanding emergency department building in Winter Garden completed by the publicly traded acute-care hospital operator Community Health Systems.

The health system is also in the middle of building a 12-story, 300,000-square-foot medical office building in Orlando’s Health Village that will be anchored by the Florida headquarters of the Rothman Orthopaedic Institute. The project is expected to be completed in late 2022.

In Apopka, AdventHealth reps are looking to build a distribution facility with more than 455,000 square feet of distribution space at 4051 Fudge Road.
