Testosterone therapy and men's health for Cypress. Six miles down Valley View — read against your baseline, and tracked.
Castellano Health Institute serves Cypress men a six-mile drive down Valley View — same doctor every visit, labs read against your own baseline instead of a population range, and the trend tracked at every follow-up.
Garden Grove · Mon–Fri 9 AM – 5 PM
The Cypress patient Dr. Castellano sees most.
He works in something measured — engineering, aerospace, a hospital, an analyst’s desk — forty-five to sixty, the kind of man who trusts a number he can see moving over time more than a verdict handed down in a fifteen-minute slot. His annual physical says “normal,” but normal is a single dot on a wide chart, and he knows the difference between one reading and a trend.
What he wants isn’t a bigger promise; it’s a better dataset. Where does his testosterone actually sit against his own baseline — not the population range? Is the estradiol accounting for symptoms the testosterone number alone doesn’t explain? Does the LH point at the testes, or at the pituitary signal above them? Those are questions a focused panel answers when someone actually reads it, and a screening tube checked against a range doesn’t.
One reading is a data point. A trend is the picture.
The weakness of the once-a-year lab isn’t only that it’s narrow — it’s that it’s a snapshot. A single testosterone value sitting inside a reference range that spans healthy twenty-five-year-olds and struggling seventy-year-olds tells you very little on its own. The signal lives in the movement: where the number is now versus where it was, and which direction it’s heading.
That’s the case for the same doctor reading the same markers at every visit. Dr. Castellano orders a focused panel — total testosterone, estradiol, LH, a complete blood count, and PSA when age calls for it — and reads each follow-up set against your own prior one, so a dose adjustment is a response to evidence rather than an educated guess. Thirty years of reading these panels is what turns a column of numbers into a direction.
When the driver is the thyroid, not the testosterone.
Sometimes the testosterone comes back fine and something upstream isn’t — an early thyroid shift, a cortisol rhythm that’s off, a fasting insulin quietly climbing. Chasing testosterone there fixes nothing. For the Cypresspatient whose numbers read borderline while the symptoms don’t, hormone support runs the deeper workup that finds the actual driver — and treats that instead.

Dr. Castellano sees Cypress 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.
The questions Cypress patients ask most before the first visit.
- How far is the clinic from Cypress?
- About six miles — down Valley View or a short run on the 22 to S Euclid. Most Cypress patients are in and out inside 90 minutes, lab draw included. Free on-site parking at the suite.
- What does the basic TRT panel actually measure?
- Total testosterone, estradiol, LH, a complete blood count, and PSA when age calls for it. It's kept deliberately lean to hold your cost down — every marker on it is there to answer a question that changes the plan. Dr. Castellano reads those numbers against your symptoms and your own prior baseline, which is where an "in-range" result can still be low for you. Wider panels exist for men whose picture points somewhere other than testosterone; they're ordered when the case calls for them, not bolted onto every workup by default.
- Do you track results over time or just at the start?
- Every visit. One reading is a data point; a trend is the actual picture. Because you see the same doctor each time, your follow-up labs get read against your last set — so a dose gets adjusted on evidence, not a guess.
Six miles down Valley View to S Euclid. Free parking on-site.
Cypress patients start with the same core program every man here does: testosterone replacement therapy with Dr. Castellano — $250 a month, labs and follow-up visits included. (The initial consultation and bloodwork before starting are a separate service and cost.)
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.
Calling after hours? Leave a message — we’ll get back to you the next business day.
