O’BRIEN LAW OFFICE
The attorney who's been on your side of the table.​
Reduce Real Estate Costs | Improve Performance | Make Smarter Decisions
​
I help companies reduce real estate costs and make smarter portfolio decisions by combining executive-level experience, legal insight, and hands-on operational expertise.
​
Today's competitive environment means organizations must optimize their real estate portfolios, cut costs, and improve efficiency all while ensuring that space aligns with business needs and strategy.
Legal counsel with
a seat at the table
Most attorneys advise from the outside. Gary O'Brien has spent 25 years on the inside — as General Counsel, Head of Real Estate, and senior advisor to executive leadership at global organizations.
​
Led by a former Head of Real Estate at Siemens, O’Brien Law Office brings enterprise-level expertise to organizations that need senior-level guidance—without building an in-house team.
When Icounsel your business, you're getting someone who has led the very transactions and decisions you are navigating now.
​
I have managed large, diverse portfolios of commercial properties, negotiated leases at scale, and delivered tens of millions in cost savings.
​
I know what good deals look like — and I know when you are leaving money on the table.
