Breathing concerns
deserve answers,
not assumptions.
A pulmonology clinic that runs the full diagnostic picture — spirometry, CT review, PFTs — for patients who've been handed an inhaler and told to come back in six months.

The questions other doctors
didn't stay long enough to ask.
We built Breathe for patients who've been told "it's probably fine" — when it clearly isn't. Each concern below maps to a specific diagnostic protocol.
"My doctor handed me an inhaler and said it's probably asthma — but nobody ran a single test."
Full spirometry with bronchodilator response, diffusing capacity (DLCO), and lung volume measurement to confirm or rule out obstructive disease — in a single morning.
"It's been eight months since COVID and I still can't climb a flight of stairs without stopping."
Post-COVID pulmonary evaluation including 6-minute walk test, exercise oximetry, and chest CT review to identify fibrotic changes or vascular involvement missed on standard X-ray.
"My toddler wheezes through every cold. Three urgent care visits, three different explanations."
Pediatric pulmonary assessment with impulse oscillometry (IOS) — no mouthpiece cooperation required — to objectively measure airway resistance in children who can't perform standard spirometry.
"The cough has been there for nine months. Everyone says it's reflux. The reflux treatment didn't work."
Systematic cough evaluation protocol: upper airway assessment, bronchoscopy when indicated, methacholine challenge for cough-variant asthma, and cough hypersensitivity testing.
From uncertainty
to a diagnosis with a name.
Most patients leave their first visit with a confirmed diagnosis, a care plan, and a clear understanding of what their lungs are actually doing.
Pre-visit records review
Our team reviews every prior imaging study, lab result, and physician note before your appointment — so we spend your time diagnosing, not catching up.
Full pulmonary function testing
Spirometry, lung volumes by body plethysmography, and diffusing capacity. The complete picture of how your lungs move air and transfer oxygen — not just a partial reading.
Unhurried clinical review
A 45-minute appointment where your results are interpreted in context. We ask about the cough that wakes you at 3am, the stairs you now avoid, the activities you've quietly stopped doing.
Advanced imaging interpretation
CT chest with HRCT protocol for interstitial lung disease, CT pulmonary angiography for vascular disease. We read your existing scans — and order precisely what's still missing.

Complex presentations — including interstitial lung disease and pulmonary hypertension — are our specialty, not a referral we make to someone else.
What changes
when you finally know.
Real patients, real diagnoses. Names and details shared with permission.
"After two years of inhalers that didn't work, I had a name for what was actually wrong with my lungs within 90 minutes of my first appointment. The relief of just knowing was enormous."
Outcome: Diagnosed on first visit after 2 years unresolved

Patricia Delgado
Retired teacher, 61 · Houston, TX
"My son was seven months old when we first came in. They used a test I'd never heard of — no mouthpiece, no cooperation needed. We had answers that day."
Outcome: IOS testing confirmed diagnosis without spirometry

James Osei
Parent · Chicago, IL
"Eleven months post-COVID. I'd been told the breathlessness was anxiety. The CT showed ground-glass opacities nobody had looked for."
Outcome: CT findings identified, treatment plan initiated within 1 week
Mei-Lin Torres
High school teacher, 38 · New York, NY
"I was 54 when I walked in convinced I had COPD. I had pulmonary hypertension. The difference in treatment is everything. I'm grateful every single day."
Outcome: Correct diagnosis led to targeted therapy, 80% symptom improvement
