About Sapphire Realty
Real estate guidance built around people.
A licensed California brokerage you can check for yourself, and one person who actually answers. Everything on this page is a fact you can verify — the licences, the legal entity behind the name, the office and the phone numbers — rather than a claim about how we feel.
The name, and the entity behind it
How the brokerage is structured
Sapphire Realty is the public name. The licensed entity behind it stays visible on this page, so you can check who you would actually be dealing with before you call.
Why this is on the page
California requires a licensee to show their licence number and the responsible broker’s name as currently licensed. We would rather set it out clearly here than leave it in small print, so that “Sapphire Realty” and the licensed corporation are obviously the same business.
Both licences can be checked on the state’s own public lookup. The lookup confirms licence status; the address it shows is the state’s record and may not match the current office listed on this page. We do not ask you to take our word for any of it.

The Castellon Team at Sapphire Realty
Sapphire Realty’s transactions are handled by The Castellon Team — led by Alex Castellon, the broker behind Alex Castellon and Associates Inc, with Alejandro (Alika) Castellon Jr., Broker-Associate, as the person you will talk to first and most.
Alika answers the phone, runs the conversation about your options and stays your contact through closing. Behind him, a small team covers listing work, offers and the paperwork between them — so you are dealing with a team around one transaction, not a call centre and not a single person doing everything.
He also writes and reviews the guidance published on this site, so the explanations you read here and the conversation you have on the phone come from the same person.
No pressure and no scripts. If a route does not fit your situation, he will say so.

What that does and does not cover
Real-estate guidance only. Nothing on this site is legal, tax, lending or insurance advice — those questions belong with a California attorney, a tax professional, your lender or an insurance professional, and the guidance here says so where they come up.
- Representing buyers and sellers in Ontario and the surrounding Inland Empire
- Explaining how each selling route and each buying stage actually works
- Writing and reviewing the guides, questions and articles on this site
Checkable, not asserted
What you can verify about us
Rather than a list of values, here is the record. Where the state or an association publishes something, we point you at it.
That is the whole list. You will not find award badges, transaction counts or review statistics on this page, because none of them have been verified — and a number we cannot show you the source for is not worth printing.
Why the seller conversation covers more ground
One brokerage can explain both routes
Most sellers are choosing between listing on the open market and accepting a direct offer. Sapphire Realty can talk through both structures, because it both lists homes with a licensed California agent and makes direct offers on them.
That means the conversation can cover both routes in one place instead of two. It does not mean the comparison is automatically neutral, and it does not mean a direct offer is available or suitable for every property. What actually applies to your home comes from the written terms and from what matters most to you — price, timing, condition, or how much you want to be involved.
Buyers too
Sapphire Realty represents buyers as well as sellers, and the property search on this site is open to everyone — current listings available through CRMLS, with no account and no form required to look.
