Clear strategy and strong representation for owners, investors, and businesses across Philadelphia and the Mid-Atlantic.
As Mentioned On
Maximize Value. Reduce Risk. Execute with Confidence.
Commercial real estate decisions are rarely just about space — they're about timing, leverage, and long-term value. Whether you're acquiring, leasing, or repositioning, you need an advisor who sees beyond the transaction — to the financial impact, the strategic fit, and the long-term value it creates.
With more than 600 successfully negotiated transactions, Jon O'Shea brings deep experience working with property owners, investors, healthcare groups, and businesses to navigate complex deals across Greater Philadelphia with clarity and precision.
What makes the difference? Jon is both a commercial real estate broker and an owner of the same types of properties he represents. He's sat on every side of these deals — as an investor, seller, landlord, and tenant. That firsthand perspective means you get more than a broker — you get an advisor who knows what's at stake and keeps your interests and goals at the center of every decision.
Commercial Advisory
From site selection to lease negotiation to disposition, I work with owners and occupiers who need a broker that understands the full picture — not just the transaction in front of them. Strategy first, deal second.
Healthcare & Medical Office
Physician practices, outpatient facilities, and healthcare operators face real estate decisions that carry long-term consequences. I bring specialized experience to every step — so you negotiate from clarity, not pressure.
Multi-tenant Investments
Whether you're acquiring your first medical office building, adding to an existing portfolio, or have decided it's time to sell, I help investors evaluate the right assets, in the right submarkets, at the right time. No hype. Just sound guidance.
Straight talk. No gimmicks. Strategy that works.
That's the O'Shea difference.
Serving Philadelphia & the Mid-Atlantic Corridor, including Philadelphia, Delaware County, Chester County, Bucks County, Southern New Jersey and Delaware.

Straight Talk on Commercial Real Estate
How to Value a Medical Office Lease or Purchase
When physicians start looking at medical office space, one of the first questions I hear is simple: is this a fair deal? Whether you are leasing, buying, or considering the sale of a property, the right value depends on more than just the asking price.
Lease Pitfalls Physicians Should Avoid
Commercial leases can contain language that creates real problems for physicians if they are not reviewed carefully. I see many doctors move quickly because they are focused on opening, expanding, or relocating their practice.
When Physicians Should Lease Versus Buy Medical Office Space
Deciding whether to lease or buy medical office space is one of the biggest real estate decisions a physician can make. There is no single right answer, because the best choice depends on cash flow, growth plans, specialty, and how long you expect to stay.
What Physicians Should Look for in a Medical Office Location
The right medical office location does more than provide space for exam rooms. It affects patient convenience, referral flow, staff satisfaction, and the long-term growth of your practice.
The Developer's Dilemma: When to Sell and Move to Your Next Project

Why Philadelphia's Warehouse Market Will Stay Red Hot
We are becoming increasingly comfortable buying things online. This isn't a trend that's going to reverse. And in order for something to be delivered, it has to touch multiple warehouses.
From One Location to Four: How Private Practice Providers Scale Through Real Estate
When healthcare providers think about expanding their practice, they usually focus on the obvious questions. But the real estate question is often the one that determines whether expansion succeeds.
What Your Medical School Never Taught You: Real Estate Strategies for Healthcare Providers
Doctors are some of the most educated people in our society. But here's something I've discovered: if you were to panel a group of ten physicians, I'd wager all ten would tell you the same thing. No one ever taught them about real estate ownership as part of their practice.
Control: The One Word That Explains Why Entrepreneurs Should Own Their Real Estate
I've worked with hundreds of business owners over the years. Different industries. Different backgrounds. Different goals. But there's one thing they all share: an affinity for control.
Inflation: The Silent Killer of Every Business P&L (And How Real Estate Ownership Fights Back)
Let me walk you through some simple math that keeps business owners up at night. Say you signed a 10-year lease back in 2015 with 2.5% annual increases. Over those 10 years, your rent has gone up by 25%. But what if inflation had been 8% instead?
Why Your Rent Check Should Be Going to Yourself: The Case for Business Owners Buying Their Buildings
