Services

Expertise, time, and leadership, scoped to your business.

Seven ways to work together, available hourly, by the half or full day, as a project, or on an ongoing retainer. Every engagement starts with a conversation about what you need.

Two audiences

Events and training are built for two kinds of rooms.

Both can be tailored to your business and booked once or as a series.

For Your Customers & Consignors

Engaging education, direct access to an expert, and hosted experiences that give your clients a reason to show up. Real versus fake demonstrations, private shopping education, and expert presence at consignment and buying days.

Plan an Event

For Your Internal Team

Product knowledge, sound intake decisions, consistent review standards, and practical operations. Introductory education for associates and buyers, and advanced development for working authenticators.

Discuss Team Training

01

Who it is for

Industry organizations, conferences, marketplaces, and leadership teams

Discuss a Speaking Engagement

Speaking & Industry Engagements

For conferences, trade associations, marketplaces, and companies that want a speaker who has actually run authentication teams and can talk about the work with candor.

Engagements can take the form of a paid keynote, a panel seat, a moderated conversation, a fireside format, or a private session for your company. I prepare each talk around your audience and the questions they are actually asking, and I am comfortable in front of executives, operators, sellers, and press alike.

Audiences leave with a grounded understanding of what human expertise does in authentication, what it takes to build trust with consumers, and where the resale industry is genuinely heading.

Available topics

Human expertise in authentication and why it still matters. Building consumer trust in pre-owned luxury. Developing and retaining authentication teams. Counterfeit challenges and how they evolve. The realities of scaling a luxury resale operation. Global pre-owned supply and the US market. Social commerce, live selling, and what sellers need to adapt. Topics can be combined or tailored to a specific theme.

Formats

Keynote, panel participation, moderation, fireside chat, internal all-hands or leadership session, and virtual presentations. Time on stage, preparation, and travel are scoped together.

02

Who it is for

Customers, consignors, VIP clients, and event guests

Plan an Event

Authentication Experiences & Events

For consignment stores, resale boutiques, rental businesses, live sellers, and marketplaces that want to give their customers and consignors direct access to an expert.

I host customer and consignor events, real versus fake demonstrations, interactive workshops, private shopping education, and expert presence at buying or consignment days. In person, sessions draw on my traveling collection of authentic and counterfeit reference examples, with guided examination and open Q&A. Virtually, I work over Zoom with detailed imagery and interactive case studies.

Your guests learn something real, your team is seen as the trusted source, and the event becomes a reason for clients to show up and bring their pieces.

Live intake support is available within an agreed brand, volume, and time scope to help your team make immediate buyout or consignment decisions. Some items require further review, and I will say so rather than force a conclusion on the spot. Every event is booked as a hosted professional engagement for my time.

In person

Guided examination with reference examples, hands-on comparison of construction and materials, hosted conversation, and Q&A. Events can be built around a launch, a consignment drive, a VIP evening, or a recurring series.

Virtual

Live sessions over Zoom using detailed imagery and interactive case studies. Well suited to distributed customer communities, live-selling audiences, and businesses with multiple locations.

Live intake support

Expert presence during buying or consignment events, scoped by brand, expected volume, and hours. I support your team's decisions in real time and flag anything that needs deeper review.

Live selling and social commerce

Channel planning for TikTok Shop, eBay LIVE, and Whatnot, including host selection, audience engagement, product storytelling, show preparation, and the operational discipline needed to turn existing inventory into a compelling live experience.

03

Who it is for

Sales, operations, buyers, intake staff, and authenticators

Discuss Team Training

Private Business & Team Training

For businesses that need their people to recognize quality, ask the right questions at intake, and know when to escalate. Training is built for your inventory and your team's current level.

Sessions cover authentication fundamentals, brand and category case studies, construction and materials, authentic versus counterfeit comparisons, research methods, image requirements, and appropriate escalation. Introductory product and intake education is designed for associates and buyers. Advanced authenticator development goes deeper into calibration, judgment, and complex cases.

Your team makes better intake decisions, speaks about product with confidence, and applies consistent standards without over-relying on a single expert.

Workshops build skill and confidence. Attending a session is not a certification, and I am careful to say so.

Introductory product and intake education

For sales associates, store staff, buyers, and new intake team members. Focused on quality signals, common red flags, documentation habits, customer conversations, and knowing when to route an item for review.

Advanced authenticator development

For working authenticators and senior reviewers. Deeper brand and category study, construction analysis, research methods, escalation judgment, and consistency across reviewers.

Formats

A single workshop or a structured series, delivered in person or virtually, always with room for questions. Materials are tailored to your categories and experience level.

04

Who it is for

Operations leaders, authentication managers, and founders

Discuss Operations Support

Authentication Operations & Team Calibration

For resale businesses, marketplaces, and authentication teams that have grown faster than their process, or that need senior operational judgment without a full-time hire.

I assess how items move through your operation, then design or refine workflows, SOPs, routing logic, serviceability decisions, escalation ownership, and quality assurance. I build onboarding paths and skills assessments, and I run training calibration so reviewers apply the same standards and exercise sound judgment. Calibration, in plain language, means making sure two people looking at the same item reach the same well-reasoned conclusion for the same reasons.

Fewer bottlenecks, clearer ownership, more consistent decisions, and a team that adopts the changes because they helped shape them.

Assessment

A structured look at your current workflow, staffing, tooling, escalation paths, and quality signals. I identify friction and prioritize what will make the biggest difference.

Implementation

Practical changes to routing, documentation, review standards, and escalation ownership. I work alongside your team rather than handing over a document and leaving.

Ongoing calibration

Recurring sessions, skills assessments, and quality reviews that keep standards consistent as people and inventory change.

05

Who it is for

Training leads, operations teams, and growing organizations

Discuss Custom Resources

White Label Training & Resources

For businesses that want durable internal resources they can present as their own, written for their inventory, their processes, and their team's experience level.

Deliverables can include brand guides, model references, intake manuals, onboarding materials, training decks, case-study libraries, and internal reference resources. Everything is developed for your audience and formatted in your identity. Permitted use, distribution, and update cadence are scoped within each engagement.

New hires ramp faster, existing staff have a reliable reference, and your training no longer lives in one person's head.

All materials are created fresh for your organization. Proprietary content from employers, clients, or authentication providers is never shared.

What can be built

Brand and model reference guides, intake and condition manuals, onboarding curricula, training presentations, case-study collections, and quick-reference tools for the floor or the review desk.

How it is scoped

We agree on audience, categories, format, usage rights, distribution, and how updates are handled. Resources can be delivered once or maintained on an agreed schedule.

06

Who it is for

Authentication teams, category leads, and training managers

Discuss a Reporting Engagement

Authentication Trend Guides & Reports

For businesses that need their reviewers and buyers to stay current without building a research function in-house.

Reports cover emerging counterfeit patterns, current authentication challenges, changing identifiers, review considerations, and recommended training priorities. Each report is tailored by brand, category, audience, or business need and can be delivered under your brand for internal use.

Your team is briefed before problems reach your intake desk, and training time goes where it matters most.

These are commissioned reporting engagements with an agreed cadence and scope, written for each client. There is no off-the-shelf archive.

One-time guides

A focused report on a specific brand, category, or challenge, often commissioned ahead of a launch, a season, or a category expansion.

Recurring updates

Monthly or quarterly briefings on an agreed set of brands and categories, with review considerations and training recommendations for your team.

07

Who it is for

Founders, executives, and category leaders

Discuss Advisory

Strategic Advisory & Enterprise Solutions

For leadership teams that want a senior advisor who understands authentication, resale economics, global supply, social commerce, and how the pieces fit together operationally.

Advisory covers authentication operations, pricing and valuation approaches, category development, provider selection, US market entry, social commerce, and connecting your business with appropriate authentication partners. I assess what your business actually needs before recommending a path, and I help put the right solution in place and make it work.

Clearer decisions, a realistic operating model, and the right partners for your volume and categories.

Through my work as Head of Luxury at Legitmark and as a senior authenticator with Real Authentication, I have direct visibility into how leading providers operate. For scaled needs, I can help you explore Legitmark enterprise solutions and potential volume pricing, subject to provider terms and fit. I do not guarantee discounts, and I recommend a provider only when it suits your business.

Retainer advisory

A monthly or quarterly arrangement for ongoing access, strategic input, and hands-on involvement in operational decisions.

Provider selection and introductions

Needs assessment, evaluation of authentication providers, and warm introductions where the fit is right. I remain your advisor through onboarding.

Pricing and valuation guidance

Practical frameworks for pricing pre-owned luxury, valuation for consignment and buyout, and category-level margin considerations.

US market entry and global supply

Advisory for global pre-owned luxury businesses seeking to understand the US customer, operating environment, channel mix, and market expectations. My perspective is informed by first-hand travel across Japan and China, where I have studied technology, inventory, authentication, and condition standards that can help raise the bar in the United States.

Social commerce and live selling

Strategy for sellers adapting to TikTok Shop, eBay LIVE, and Whatnot. This can include selecting and preparing the right host, shaping a show around the audience, presenting product clearly, and matching inventory to the speed and interaction of a live channel.

How engagements work

A simple path from first conversation to delivery.

  1. 01

    You share the goals

    Tell me about your business, the audience or team involved, what you need to accomplish, your timing, and whether you prefer in person or virtual.

  2. 02

    I develop a custom scope

    I come back with a clear proposal that covers format, preparation, customization, follow-up, travel, and any report or resource updates, each scoped appropriately.

  3. 03

    We deliver together

    The agreed session, project, event, or ongoing advisory support, with your team involved so the work sticks after I leave the room.

Clients engage me for professional time and expertise. There are no per-item fees and no consumer authentication service on this site.

Questions

Frequently asked.

Are services available virtually?

Yes. Training, events, advisory, and speaking can all be delivered virtually. Virtual sessions use detailed imagery, interactive case studies, and live discussion over Zoom.

Do you travel?

Yes. I am based in New York City and travel for in-person training, events, speaking, and operational work in the United States and internationally. Travel is scoped as part of the engagement.

Who is training for?

Sales associates, store operations, buyers, intake teams, and authentication teams. Introductory sessions suit people who handle product and customers. Advanced sessions are built for working authenticators and senior reviewers.

Can engagements be ongoing?

Yes. Many clients begin with a workshop or assessment and continue with a training series, recurring calibration, or a monthly advisory retainer. Hourly, half-day, full-day, project, and retainer arrangements are all available.

Can resources be white labeled?

Yes. Guides, manuals, decks, and reports can be developed in your brand for internal use. Permitted use, distribution, and updates are agreed within each engagement.

How do authentication provider introductions work?

I start by understanding your volume, categories, and operating model. If a provider is a good fit, I make a warm introduction and stay involved as your advisor. For scaled needs, I can help you explore Legitmark enterprise solutions and potential volume pricing, subject to provider terms and fit. Recommendations are never guaranteed discounts.

Do you authenticate individual items for consumers?

This practice focuses on business consulting, education, and events. If your business needs ongoing item authentication, I am glad to discuss suitable provider options as part of an advisory conversation.

Authentication assessments are made by highly trained human experts. AI is not used to determine authenticity.
