Most firms in this market are built solely to close transactions. Rosenthal & Excell is structured from the ground up for comprehensive real property asset management.

While we provide expert brokerage, purchasing, and leasing services, we treat them as tools for long-term wealth preservation, not one-off commissions. In fact, our clients typically do not acquire an asset unless we are mutually ready and willing to manage it long-term.

We approach your real estate from an owner’s business perspective, protecting physical asset health and tenant stability through every market cycle. Our clients are exclusively individuals of significant wealth, public government agencies, and established regional businesses who demand fiduciary-level oversight.

What we manage

Shopping centers and medical buildings, mostly.

Seven of the project properties in our client portfolio carry medical tenants, from a hospital-adjacent building in Murrieta to urgent care, dental and optometry suites in Menifee and Temecula. Most of the rest are neighborhood retail.

Against a national firm

Your building will not be handed to a rotating team.

A national brokerage will assign your asset to a team, and that team will change. The people who tour the property, negotiate its leases and answer when a tenant calls are rarely the people who won the account.

This firm has no outside agents and no bench to rotate. Howard Rosenthal and Guy Excell have personally run every engagement since 1987, and they will run yours. That is the difference between a report about your asset and knowledge of it.
