Two licenses, and what each one actually permits.
Pennsylvania licenses the firm and the person separately, and the distinction matters more than it sounds. A company license lets a business hold itself out as a broker. It does nothing on its own. It only has effect because a named individual is answerable for everything done under it.
Both were issued on September 17, 2026 by the State Real Estate Commission and run through May 31, 2028. Both certificates are below, exactly as the Commission issued them.
RB070473, the company

That responsibility is not delegable, and a complaint about anything done here lands on this license.

Verify it yourself.
A license number printed on a website is worth nothing on its own. Anyone can type a number. The Commonwealth publishes the register, so check it there.
Go to pals.pa.gov/verify, search either number, and you should see the license type, the status, the expiration date, and any disciplinary history. If what you see there ever disagrees with what you see here, the Commonwealth is right and we want to know about it.
Memberships, and what they oblige us to.
Membership is not a license to practice and we will not present it as one. The license above is what permits us to work. Membership is a set of obligations we took on voluntarily, on top of the law.
REALTOR® membership runs in three tiers and you join all three together: the local association, the state association, and the national one. Nest joined through the local body.
Greater Lehigh Valley REALTORS® (GLVR)
The local association, covering Lehigh, Northampton and Carbon counties, the heart of the area this firm works. GLVR owns and operates the Greater Lehigh Valley Multiple Listing Service, and our membership carries MLS access. That is how a listing we take reaches every other agent in the valley, and how we see theirs.
Pennsylvania Association of REALTORS®
The state association. Each of our advisors holds this membership in their own name rather than under a shared firm login.
National Association of REALTORS® (NAR)
The national body. Its Code of Ethics is the part that matters to a client: it is enforceable against us through a peer review and mediation process that exists whether or not anyone goes to court, and it asks more of us in several places than Pennsylvania law does.
Only a member of the National Association of REALTORS® may use the term REALTOR®. It is a registered collective membership mark owned by NAR and it is not a synonym for a licensed agent. Every licensee is regulated by the Commonwealth; not every licensee is a REALTOR®.
If something here is wrong.
Tell us and we will correct it the same day. If the concern is more serious than a typo, you do not have to come through us at all: complaints against any Pennsylvania licensee go to the State Real Estate Commission, and ethics complaints against a REALTOR® go to the local association.
