Summit Diner Exterior Restoration Historic Grant

The Summit Diner, at the corner of Summit Avenue and Union Place, has completed a full exterior restoration that returned the 1939 O'Mahony stainless-steel structure to its original appearance. The months-long project was funded through a $50,000 national historic-preservation grant, demonstrating community commitment to preserving a significant local landmark and gathering space.

Historic Diner and Community Fixture

Union County Life readers in Summit recognize the diner as a fixture at that corner since 1929, when the site opened as a lunch wagon serving railroad workers and downtown employees. The current stainless-steel O'Mahony model arrived in 1939, establishing the iconic structure that has defined the corner for nearly a century.

The diner's longevity represents continuity and community connection—a place where generations of Summit residents have gathered for meals, conversation, and neighborhood community.

Family Ownership and Stewardship

The Greberis family has owned and operated the diner continuously since 1964, when Michele's father George Contorousis and Jim's uncle John Greberis purchased it. Michele Greberis and her husband Jim now own the diner; Jim has worked there daily since before they married, reflecting multi-decade family commitment to the business.

Long-term family ownership often signals stability, care for place, and investment in community relationships that extend beyond profit—commitments reflected in the decision to invest in historic restoration.

Restoration Scope and Details

The restoration addressed specific exterior elements of the 1939 structure. Gutters were repaired. Missing black molding was replaced. The art deco door was restored. Historically similar energy-efficient lighting was installed, balancing modern efficiency with preservation authenticity.

The enamel panels were cleaned rather than repainted—a deliberate preservation choice that kept the original material intact and honored the building's historic character.

The diner's sign, which had been down for months after a truck struck the corner of the building, was restored and re-electrified as part of the project, returning the iconic visual marker to the corner.

"Our sign is now back up and electricity restored," Michele said. "It's wonderful to see the diner shine once again."

Restoration Team and Design Oversight

R.J. Forst Contracting completed much of the hands-on work. Peter Greberis, AIA, LEED-GA, Vice President at MKDA in New York City, worked closely with contractors to ensure the exterior remained true to its 1939 design—critical for historic preservation integrity.

Architect Tom Conway of Kelly, Rosen, Conway Architects provided an early façade review that supported the grant application, contributing technical expertise to the preservation process.

Summit Downtown, Inc. Executive Director Nancy Adams coordinated the grant submission under a tight deadline. "I had just one day to pull everything together. I worked with the owners and gathered information online to submit it in time. I was thrilled my application was successful," Adams said.

Michele credited Adams directly: "Nancy got us in under the wire."

National Preservation Recognition

The National Trust for Historic Preservation and American Express are involved in the Saving Places program, which the diner is part of—a national initiative recognizing and supporting historic preservation efforts.

Carol Quillen, President and CEO of the National Trust, noted: "For generations, neighbors have gathered here, shared stories, made new connections, and enjoyed regional cuisine that often reflects our nation's global roots."

Madge Thomas, Head of Corporate Sustainability at American Express, added: "What started as a pandemic response has grown into a movement to uplift the historic restaurants that shape our neighborhoods and connect generations through food."

Local Recognition and Awards

The diner holds significant local recognition: #1 Best Diner in New Jersey for 2025, voted by New Jersey Digest readers, and Best NJ Diner Breakfast from 94.3 The Point. These awards reflect both customer appreciation and media recognition of the diner's quality and community standing.

Community Partnership and Social Impact

The diner maintains an active partnership with the Other Fellow First Foundation, which marked its 25th anniversary last year. The foundation's 19th Annual Frozen Turkey Drive is planned for this fall, continuing the diner's involvement in community charitable work.

The partnership reflects how local businesses become anchors for community service and charitable efforts, extending their role beyond meal service to social impact.

Business Vitality and Community Connection

"We are fortunate that we have loyal customers and new customers coming in. It is a busy little place," Michele said—reflecting the diner's ongoing relevance and community use despite changing neighborhood contexts and economic pressures on independent restaurants.

Historic Preservation and Community Asset

The Summit Diner restoration represents investment in a community asset that transcends commercial value. Historic diners serve as public gathering places, repositories of neighborhood memory, and architectural landmarks that shape community identity and sense of place.

For Summit residents, the restored diner represents commitment to preserving shared community history and maintaining spaces where neighborhood connection can continue to occur.
