Expert Allergy, Asthma & Immunology Care in Northern Virginia

When you’re managed by a large, corporate-owned allergy group, you often see whoever’s on the schedule that day. Here, you always see Dr. Ispas.

• Independent, physician-owned practice – not part of a corporate roll-up, so decisions about your care are made by your doctor, not a management company
• Personalized care from the same physician at every visit – Ispas gets to know your history, your triggers, and what’s actually worked for you
• Over 25 years of experience diagnosing and treating allergic, asthma, and immune conditions
• Same-week appointments when available – because allergy and asthma flare-ups don’t wait
• Care for children (5+) and adults – one practice for the whole family
• Advanced biologic therapies for severe asthma, allergic disease, and nasal polyps, alongside traditional treatment options
• Allergy shots prepared in-house by our own clinical team – no outsourced mixing, no delays
