Gary Isenberg is the Founder and President of Iron Mountain Hospitality (IMH) – a firm built to deliver high-touch hotel consulting, hotel asset management, and hospitality expert witness services grounded in more than four decades of hands-on experience. Owners, investors, operators, and trial attorneys across the country trust Gary to help them navigate the full complexity of the hospitality business, whether that means protecting an asset, growing a portfolio, or winning a case.
Gary’s career started on the front line. He began as a doorman at the Sheraton Russell Hotel while in college – a ground-floor start that gave him direct, unfiltered exposure to guest service and hotel operations. Over a 17-year tenure at ITT Sheraton, he completed the corporate training program and advanced into senior leadership across operations, finance, and information technology, serving in both property-level and corporate roles. That experience spanned hotels ranging from 155 to 1,800+ rooms – full-service, convention, luxury, all-suite, and boutique properties across the U.S. and several international markets.
After Starwood acquired ITT Sheraton, Gary was recruited as Chief Operating Officer for Field Hotel Associates, a regional hotel owner, operator, and developer. There, he led development, repositioning, and rebranding initiatives that lifted property performance and guest satisfaction. He later founded and led the Asset Management and Consulting Services division at LW Hospitality Advisors, building a platform that oversaw more than 50 hotels nationwide while growing a consulting practice focused on measurable gains in asset value and operational efficiency.
At Iron Mountain Hospitality, Gary brings all of that experience to his clients through customized, data-driven advisory and asset management services. His approach pairs strategic thinking with a genuinely hands-on method – so each property's unique character is preserved while its operations stay aligned with the goals that protect profitability and sharpen competitive positioning.
We see the big picture while addressing the smallest operational details – because both determine whether a hotel wins or loses.
Every recommendation comes from real-world experience and proven methodology. No theory. No guesswork. Just what works.
No two properties are alike, so no two strategies should be either. We build every plan around your specific goals, market, and challenges.
We develop tailored metrics tied to the KPIs that actually move the needle – using data to guide decisions, track progress, and deliver results you can see.
As a true owner advocate, every decision we recommend is made to protect your investment and build long-term value.
Gary has personally owned and operated hotels. That perspective – of an owner who has had real money on the line – shapes every advisory and litigation engagement.
Whether you need a trusted hotel expert witness for an active litigation matter, or a seasoned hotel advisor to protect and grow your investment, Gary Isenberg and the IMH team are ready to help. Let's talk about your next move.
