Senior authentication leadership at The RealReal through years of rapid growth. Built the luxury category at Legitmark.
My experience connects hands-on authentication expertise with team development, operational judgment, and the commercial realities of resale.
I have spent more than a decade inside luxury resale, building authentication standards, training reviewers, resolving the escalations no one else wanted, and designing the workflows that let businesses scale without losing trust. Businesses retain me for that judgment, for my time, and for my ability to develop the people and operations that make quality repeatable. I still authenticate every day, and across all of my work and personal review, not through any single service, I handle roughly half a million dollars of luxury fashion in an average week before counting the team I oversee, which keeps my advice honest and current.

Businesses I have supported in authentication, pricing, consulting, or advisory capacities.
Supporting marketplaces, sellers, and businesses around the world in all things luxury resale is some of the work I am proudest of. Whether the need is training, authentication support, pricing, consulting, or advisory, I love helping people sell luxury with confidence, and the relationships built along the way keep shaping how I see this industry.

Examples of the work
Categories built, teams calibrated, operations made repeatable.
At Legitmark I built the luxury category from the ground up, from authentication standards and image requirements through team training and quality calibration.
At The RealReal I led fashion authentication as a Senior Manager while the business scaled, owning standards, training, quality assurance, and the complex escalations that shape a company's reputation.
Independently, I have advised resale businesses internationally on authentication operations, pricing, and valuations, including an ongoing expert presence for a luxury resale client with pop-in placements at Holt Renfrew in the Greater Toronto Area.
Travel throughout Japan and China has given me a first-hand view of pre-owned luxury technology, inventory, authentication, and condition standards that are ahead of much of the US market. I now help businesses translate that global supply and operating knowledge for the US opportunity.
I also advise sellers entering social commerce and live selling through TikTok Shop, eBay LIVE, and Whatnot, from choosing the right host to presenting inventory with the clarity and energy a live audience expects.

Nhu's Clues
Learning to see. One clue at a time.
Authentication is a daily practice of noticing. Stitch counts, hardware engraving, heat stamps, materials, and above all context clues. I named my method after the habit itself, and I teach it to the teams and audiences I work with.
