Men's health and TRT for Santa Ana. Five miles west on the 22 — for the man whose body is the business.
Castellano Health Institute serves Santa Ana men a 5-mile drive west on the 22 — same doctor every visit, full in-house labs, the practice that reads the panel before writing the script.
Garden Grove · Mon–Fri 9 AM – 5 PM
The Santa Ana pattern Dr. Castellano hears most.
Construction, trades, physical labor, long shifts. The Santa Ana patient picture isn’t a man chasing peak performance. It’s the guy whose body has been the business since his twenties, who is now in his late forties or fifties, who is still the primary provider, and who needs the energy to finish the workday and have something left over for family at night.
Wear and tear is real. The pattern Dr. Castellano sees from Santa Ana: testosterone has slipped, sleep has degraded under decades of physical work, the recovery curve has shrunk year over year. He’s not asking for a Hollywood plan. He’s asking for the body to keep cashing the checks the work writes. That’s a hormone and metabolic conversation the labs can answer honestly.
The honest read on a body that’s been the business.
Decades of physical work leave a real record in the labs — testosterone slipped, sleep degraded, the recovery curve shorter than it was at thirty. The honest part is what comes next. Dr. Castellano will tell you which of that is reversible with a well-built protocol and which is wear you manage rather than undo — based on your panel and your history, not on what a pitch promises.
That candor cuts both ways. If the labs say a focused hormone or metabolic plan can give you back the energy to finish the day with something left over, he’ll say so and show you the numbers behind it. If the bigger lever is sleep, or a medication interaction, or the metabolic side, he’ll say that too — even when it isn’t the answer you drove in hoping for. What you get is the realistic outcome a disciplined plan can hold, and only the parts of it your labs actually call for.
Same doctor, every visit. From Santa Ana to your follow-up.
The drive from Santa Anabuys continuity: one doctor — Dr. Castellano, board-certified in Family Medicine, three decades in — who carries your chart and reads it himself, every visit. And TRT isn’t the only conversation worth having; for the wear-and-tear picture that isn’t neatly low-T, hormone support runs the wider panel that often surfaces a thyroid or cortisol pattern.
Coming soon.
Dr. Castellano sees Santa Ana men every week. Their before-and-after stories will land here as patients give consent to share. In the meantime, ask about results in person — bring your most recent labs and we’ll show you how the trend lines look in practice for Santa Ana patients.
The questions Santa Ana patients ask most before the first visit.
- How far is the clinic from Santa Ana?
- Five miles west on the 22, exit S Euclid. Most Santa Ana patients are in and out of the office inside 90 minutes including the lab draw. Free on-site parking at the suite.
- What's the typical protocol cost?
- TRT is a flat $250 a month — that includes the medication, the lab work, and the monthly follow-up. No package add-ons, no contract. If TRT isn't the right call after the labs come back, no one is locked in.
- Do you see men with long-running physical-work histories specifically?
- Yes. The wear-and-tear pattern needs labs read carefully — testosterone, thyroid, cortisol, sometimes a metabolic recheck. The protocol gets sized to what the panel actually says, not to a default the patient came in expecting.

Call the office to set up a 1-hour consult with Dr. Castellano. Bring whatever bloodwork you have on file — or fresh labs get ordered up front. Either way, you’ll leave with a real read on what’s going on.
