The Team

Four people. One mission.

We didn't recruit from a job board. This team was forged over a decade of friendship, business, and the shared belief that just because something has been done the same way for 10, 20, 50 years doesn't mean there isn't a better way.

Jonathan McDermott

Founder · Marketing · Sales · Training

Jonathan built JH Concierge from the ground up — starting with a single vacation rental in Fort Lauderdale that he purchased sight unseen in a city he'd never visited. He turned it into a flawless 5.0-rated property across every platform, and in the process discovered a broken system: hosts everywhere were surrendering their most valuable asset — their client and guest relationships — to platforms that couldn't care less about them.

But hospitality wasn't the starting line. Jonathan showed up with twenty years of sitting across the table from business owners — learning what they needed, what they were missing, and what they'd been doing wrong for decades without knowing it.

10 yr Verizon Information Services — B2B media sales across print, digital, social, and visual channels at enterprise scale. Learned how businesses communicate, market, and convert.
10 yr Medical & Dental Equipment Sales — High-tech materials, instruments, and equipment. Consultative selling to the most skeptical, educated buyers in any industry.
Google Training Manager — Trained and developed businesses across the United States and Canada for Google. Taught owners and teams how to market, sell, and grow — at national scale.
4 yr Jonathan's House — Owner-operator. 5.0 rating. Proof that this isn't theory. Active volunteer firefighter. NYC metro area resident running a Fort Lauderdale operation remotely — because the systems work.

Joe Lanza

Director of Business Strategy · Negotiations · Finance

Joe is the person you want across the table when money, terms, and leverage are on the line. A business owner and investor with over a decade of experience structuring deals and protecting the bottom line, Joe brings the operational discipline that turns a great idea into a sustainable business.

At JHC, Joe structures every partnership, pricing model, and vendor agreement. When a client pushes back on terms, Joe knows when to hold the line and when to bend — because he's been on both sides of that conversation in his own business. His network of business relationships across multiple industries makes him not just JHC's strategist, but one of its most potent sales channels.

Jason Ren

Systems · Tech Strategist · Code Architect

Jason is the engine behind everything the client sees and everything that runs invisibly in the background. A systems thinker and code architect, Jason translates JHC's vision into scalable technology — the portals, the guest guides, the onboarding flows, the analytics, the infrastructure that makes a one-person operation look like a team of ten.

As a business owner with deep relationships in the medical community, Jason brings something rare: a technologist who also sells. He understands what it means to sit across from a doctor or practice manager and earn their trust. That dual fluency — tech and people — is what allows JHC to scale without losing the personal touch that makes it work.

Rob VanVoorhees

Sales · Relationship Coach

Rob is the future of JHC's sales operation — and he's already running. With deep roots in the dental industry and a network of professional relationships built through years of face-to-face selling, Rob brings the energy, hunger, and relationship instincts that turn introductions into clients and clients into advocates.

What makes Rob dangerous is his coachability. Mentored directly by Jonathan, Rob doesn't sell from a script — he sells from conviction. He understands the JHC philosophy because he lives it: show up, ask the right questions, deliver more than you promised, and never let a relationship go cold. His dental industry connections give JHC an immediate second sales channel in one of its most promising verticals.
