Engineering Precision Meets Local Real Estate Expertise

Whether you are an active-duty military family executing a fast-paced PCS move, a veteran, a diplomat, or a local homeowner, buying or selling a home in the D.C. Metropolitan Area requires high-level strategy and relentless attention to detail.

Born in Lima, Peru, and bilingual in English and Spanish, I made Northern Virginia my home in the late 90’s. Before entering real estate, I earned my Bachelor’s Degree in Computer Engineering from George Mason University, followed by a Master’s Degree in Telecommunications from George Washington University, and served as a Patent Examiner at the U.S. Patent and Trademark Office (USPTO).

I bring that same analytical precision, negotiation rigor, and problem-solving mindset to every real estate transaction—from single-family homes and townhouses to luxury penthouses.

Military Spouse & Veteran Family

Deep Military Connection & Proven Results

Military expertise runs deep in my family. My husband, Elliot Tommingo, is a retired U.S. Marine Corps Major and former Director of the DC Mayor's Office of Veterans Affairs. Combining his veteran background with my full-time local real estate expertise gives military families relocating to the DMV an unrivaled advantage as I understand the unique pressures of PCS timelines, remote home buying, and out-of-state listing preparation.

High Profile Record Sale

A career highlight includes my involvement in the sale of Vice President Kamala Harris’s D.C. condominium, which was featured in The Washingtonian and House Beautiful (listed under my maiden name, Diana Flores).

Diverse Clientele

I regularly advise military service members (Army, Marine Corps, Navy, Air Force, Space Force, Coast Guard), veterans, civilian buyers and sellers, diplomats, World Bank/G4 visa holders, corporate transferees, and first-time home buyers.
