John Rex Charter Elementary has purchased a three-story office building in downtown Oklahoma City for $5,075,000, setting the stage for the district's first high school campus to open its doors in Fall 2027. The property, known as The Athenian, sits at 615 N. Hudson Ave. and totals 31,215 square feet, meaning the charter school paid roughly $162.58 per square foot to secure the site.
According to CoStar, the deal was an owner-user sale, with John Rex Charter Elementary acquiring the building from a private individual who wanted to downsize his real estate portfolio. The Athenian will be converted from office space into a public charter school, joining a growing footprint of downtown campuses run by the John Rex system. Built in 2001, the building sits on a 0.24-acre corner lot within a Federal Opportunity Zone and Oklahoma City's Downtown Business Improvement District, according to Commercial Search.
A Downtown Campus Network Years in the Making
John Rex opened its original elementary campus at 500 W. Sheridan Ave. in 2014, then expanded by leasing the McAlpine Center at 428 W. California Ave. in 2020 for middle school grades before opening a junior high campus at the historic Carnegie Centre in August 2025, per OKC VeloCity. The Athenian purchase extends that pattern into high school territory for the first time, giving the charter network a real path toward a complete downtown PK–12 pipeline.
The timing lines up with broader shifts in Oklahoma City's office market. Commercial real estate firm Price Edwards & Company reported the city's office market closed out 2025 with a 25.9% vacancy rate across 17.8 million square feet of inventory, conditions that have made Class B buildings like The Athenian more affordable for non-corporate buyers, including schools looking to convert office space for classrooms.
Leadership Already in Place Ahead of Fall 2027
John Rex named Dr. Rhonda Hart as founding principal of the new high school in May 2026, alongside Carmen Oswalt as Chief Academic Officer, according to John Rex Charter School. The two are expected to spend the 2026–2027 school year preparing curriculum and operations ahead of the campus opening. The Charter School Growth Fund reports the high school model is built around five industry-aligned career pathways designed to connect students directly with downtown employers through project-based learning and internships, part of a broader goal of establishing a full PK–12 network by 2028.
Even with the sale finalized, conversion work, zoning approvals and facility retrofits remain ahead before students can move in, since The Athenian was built as office space rather than a school. Its downtown location puts it within walking distance of federal government complexes, the Oklahoma City National Memorial & Museum, and the Paycom Center, according to Commercial Search.
Tied to the City's Housing Ambitions
The expansion isn't happening in a vacuum. Oklahoma City's draft downtown master plan, which sets a goal to quadruple downtown housing by 2060, explicitly names the creation of a downtown John Rex high school as a core piece of that strategy, as Hoodline previously reported. City planners view accessible K-12 education downtown as essential to keeping families in the urban core as residential development accelerates.
John Rex's academic track record has helped fuel that confidence. A 2019 report card analysis found John W. Rex Charter Elementary earned an “A” rating from Niche, with 52% of its then 446 students testing proficient in math and reading, well above Oklahoma City district averages of 30% in math and 28% in reading at the time. The school was established in 2014 as a hybrid public school within an Academic Enterprise Zone, a structure that required at least 60% of families in its attendance boundary to qualify for free and reduced-price lunch, before the charter was restructured in 2019 to allow independent expansion into higher grades, according to Oklahoma City Free Press.
The school's profile has also risen on the state policy stage. Oklahoma Governor Kevin Stitt held a formal bill-signing ceremony inside a third-grade classroom at John Rex Charter Elementary in April to enact Senate Bill 1778, a literacy reform mandating retention for struggling third-grade readers starting in the 2027–2028 academic year, backed by more than $43 million in state funding for reading interventions and teacher academies, per the Oklahoma Council of Public Affairs. With that visibility and a downtown building now in hand, John Rex is positioning itself as a central player in both Oklahoma City's education landscape and its long-term urban growth plans.
