Thinh Vo, MDBoard-Certified Pulmonologist & Critical Care Specialist in Houston, TX

Pulmonologists specialize in the lungs and the respiratory system — how you breathe, what makes breathing harder than it should be, and what's causing it. Dr. Vo diagnoses and manages conditions like asthma, COPD, chronic bronchitis, shortness of breath, recurrent pneumonia, interstitial lung disease, pulmonary hypertension, and sleep-related breathing problems. If you've been dealing with a cough that won't go away, breathing that's gotten harder over time, or a lung condition that hasn't responded to treatment, that's what pulmonology is for.

Your primary care doctor is the right first stop for most breathing concerns. But if treatment isn't working, the diagnosis isn't clear, or symptoms keep progressing — it's worth seeing Dr. Vo. Asthma that isn't controlled on standard medication, a COPD diagnosis that needs proper staging, unexplained shortness of breath, or abnormal chest X-ray findings are all good reasons to come in. A pulmonologist doesn't replace your primary care doctor. He adds a layer of expertise when the lungs need more attention than a general visit can provide.

Yes — both are core to what he does. Asthma and COPD are the two most common chronic lung conditions, and they're also among the most undertreated. A lot of patients have been managing on the same inhaler regimen for years without anyone reviewing whether it's still the right plan. Dr. Vo looks at current symptoms, lung function, triggers, and medication effectiveness and adjusts accordingly. The goal isn't just keeping symptoms tolerable. It's getting to a point where the condition isn't running your life.

Dr. Vo starts by understanding the full history of your breathing — when symptoms started, what makes them worse, what treatments you've tried, and what imaging or lung function tests have already been done. Bring whatever records you have, including any recent spirometry or chest imaging. Depending on what he finds, he may order additional testing that day or at a follow-up. You'll leave knowing what's going on and what the next step is — not a vague instruction to come back in three months.

It depends on the condition and how stable it is. Some patients come in a few times a year for monitoring and medication review. Others need closer follow-up while a treatment plan is being adjusted. What Dr. Vo won't do is set a plan and disappear. Lung conditions change over time — seasonally, with other illnesses, as medications get added or removed. Staying on top of it means regular touchpoints, not just a visit when something goes wrong.

Lung health and overall health are more connected than most patients realize. COPD and heart disease often coexist. Kidney disease affects fluid in the lungs. Sleep apnea overlaps with hypertension. Being inside a multispecialty practice means Dr. Vo can coordinate directly with nephrology, primary care, or pain management when those connections matter — without you managing multiple referrals to separate offices. The right hand knows what the left is doing. That's harder to find than it should be.

Spirometry, bronchoscopy, pulmonary function testing, fractional exhaled nitric oxide testing, and sleep study interpretation are all within his scope. These aren't diagnostic boxes to check — each one is designed to answer a specific question about how the lungs are working and why. Dr. Vo explains what each test is looking for before it's done and goes through the results in plain language afterward. You'll understand what the findings mean for your treatment, not just what the numbers say.
