Each visit is customized to help you breathe better and live healthier — wherever you are in Merced County.

We provide comprehensive allergy testing in Merced, including skin prick, intradermal, and blood (IgE) tests to detect environmental, food, and drug triggers. Understanding the cause of your symptoms lets us create targeted, long-term solutions.

As a leading asthma specialist in Merced, Dr. Bashir performs lung function (spirometry) tests and tailors treatment plans that may include inhaler training, controller medication, and trigger avoidance strategies.

Many chronic sinus and ENT issues stem from allergies. Our Merced sinus and allergy clinic treats inflammation, pressure, and nasal blockage by targeting underlying allergens.

Our Merced immunotherapy clinic offers both allergy shots and sublingual immunotherapy to desensitize your immune system. Over time, this reduces allergic reactions and dependence on medications.

We help patients manage food allergies, medication reactions and insect sting allergies safely. We create personalized plans and teach how to use epinephrine (EpiPen®) if needed.
