Men's health and TRT for Westminster. Three miles down Euclid, when the business runs on you.
Castellano Health Institute serves Westminster men a 3-mile drive down S Euclid St — the closest in-person specialty practice for the business owner whose calendar has no room for a complicated medical relationship.
Garden Grove · Mon–Fri 9 AM – 5 PM
The Westminster pattern Dr. Castellano hears most.
Westminster runs on small business. The corner store, the salon, the auto shop, the restaurant. The Westminster patient who walks in is often a fifty-plus, second-decade business owner who is still doing the work — opening, closing, payroll, the customer who has to be handled personally. Fatigue gets explained away as “I’m just running a business” for ten years before he comes in.
Sleep has degraded but he assumed that was the job. Energy has narrowed but he assumed that was age. The labs almost always say something more specific: testosterone has dropped, sometimes thyroid is involved, sometimes a long-running medication is interacting with the picture. The fix usually isn’t dramatic. The fix is reading the panel honestly, the first time, and matching the protocol to what’s actually there.
How the Westminster TRT options compare honestly.
Westminster has very few local specialty TRT options. The closest commercial chain clinic is roughly 5 to 7 miles away. Telehealth competes too. Castellano sits 3 miles down S Euclid — the closest in-person specialty option in the area.
The honest tradeoff for a Westminster business owner: continuity of care is unusually high-value when your calendar can’t absorb re-explaining your history every visit. Same doctor every visit, full in-house labs, one chart that keeps building. Three miles is a low bar to clear when the alternative is starting from scratch with a new provider every time.
Same doctor every visit. From Westminster to your follow-up.
When you drive in from Westminster, 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 Westminster patient who wants the cheap evidence-based first line, medical hair-loss evaluation often costs less than thirty dollars a month — before surgical referral is even on the table.

Dr. Castellano sees Westminster 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 Westminster patients.
The questions Westminster patients ask most before the first visit.
- How close is the clinic from Westminster?
- Three miles down S Euclid St — often a 10-minute door-to-door drive. Most Westminster patients are in and out of the office inside 90 minutes including the lab draw. Free on-site parking at the suite.
- What if I can't take much time off work?
- After the initial 1-hour visit, follow-ups can be telehealth where appropriate. The 6-week recheck and quarterly labs are typically in person; routine adjustments can happen by phone or video.
- Do you see small-business owners specifically?
- Yes. The "running it all on me" profile is common enough that the practice runs around it — efficient scheduling, no extras you don't need, a real read on the labs the first time so the plan doesn't need three revisits to land.

One conversation tells you whether this is the right fit.
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.
