Men's health and TRT for Costa Mesa. Eleven miles up the 55 — same doctor, every visit.
Castellano Health Institute serves Costa Mesa men an 11-mile drive north on the 55 — one physician who reads your labs in the room with you, flat monthly pricing, and a chart that never changes hands.
Garden Grove · Mon–Fri 9 AM – 5 PM
The Costa Mesa pattern Dr. Castellano sees most.
The Costa Mesa patient picture is the high-responsibility professional — running a team, a book of business, or a company out of the South Coast Metro corridor. Calendar packed, decisions all day, travel in the mix. The complaint is rarely “I think my testosterone is low.” It’s “I’m flat by Thursday, the gym stopped working, and I’ve been calling it stress for three years.”
Stress and low testosterone overlap on the surface — fatigue, short fuse, poor sleep, drive that’s gone quiet. They separate cleanly on a lab panel. Dr. Castellano runs the full picture — testosterone, thyroid, cortisol, metabolic markers — and reads it with you in the room. If the panel says hormone deficiency, there is a protocol. If it says three years of compounding workload, the honest answer is different, and you’ll hear that one too.
How the Costa Mesa TRT options compare honestly.
Costa Mesa men have real options at close range. Telehealth reaches everywhere — convenient when the case is simple and the protocol is already working. The Newport-adjacent concierge clinics are a short drive south — full-service memberships with a real physician relationship, priced accordingly. Castellano Health Institute sits eleven miles the other direction, up the 55 in Garden Grove.
The shape of the practice is the difference: one doctor, three decades in, who draws and reads your labs in-house and carries your chart personally — at a flat $250 a month for TRT, labs and follow-ups included, with no membership tier on top. For the man comparing a concierge retainer against a specialist visit, that math is worth running before you sign anything.
Same doctor every visit. From Costa Mesa to your follow-up.
When you drive in from Costa Mesa, you’re not joining a chain. You’re starting a relationship with one doctor — Dr. Castellano (UC Irvine–trained, board-certified Family Medicine, anti-aging fellowship credentials, three decades in practice). Same physician, same conversation, every appointment.
And TRT isn’t the only conversation worth having — for the Costa Mesa professional thinking past this quarter, anti-aging care is the longer plan: muscle mass, bone density, and metabolic function defended over decades, not patched for a season.
Coming soon.
Dr. Castellano sees Costa Mesa 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 Costa Mesa patients.
The questions Costa Mesa patients ask most before the first visit.
- How far is the clinic from Costa Mesa?
- About eleven miles — up the 55 to the 22, exit S Euclid. Most Costa Mesa patients are in and out of the office inside 90 minutes including the lab draw. Free on-site parking at the suite.
- How does this compare with a concierge membership?
- Castellano Health Institute is fee-for-service with one flat number for TRT — $250 a month, labs and monthly follow-ups included. No annual membership, no tiers, no per-script charges. You're paying for the physician's time and judgment, and the visit runs as long as the case requires.
- Can visits work around a heavy work and travel schedule?
- Yes. Because the same physician carries your chart, follow-ups don't restart from zero after a busy quarter. Labs get drawn in-house on the same visit, and once a protocol is stable, Dr. Castellano sizes the follow-up cadence to your calendar — not to a clinic template.
