Doctors Theodore J. Chu, Anlin Xu, Katherine S. Nelson, and John S. Kellogg

All four physicians in our practice are Board-certified by the American Board of Allergy and Immunology, and either American Board of Internal Medicine or American Board of Pediatrics. We see both children and adults with asthma, allergic and immunologic diseases but do not practice general medicine.

We specialize in the diagnosis and treatment of hay fever, asthma, sinus diseases, chronic cough, recurrent infections, hives, eczema, other skin allergies, food allergy, insect allergy, and pet allergy.

Serving a culturally diverse Bay Area, we are sensitive to different needs of each of our patient populations. Each of our doctors has special interests such as dermatologic contact allergies, patch testing, food allergy, chronic sinusitis, refractory asthma, aspirin sensitive asthma, and pollen and mold identification and counting. Dr. Xu speaks fluent Mandarin and Shanghainese, and we have staff members who speak Mandarin, Spanish and Tagalog.

If you have special concerns, please ask our friendly receptionists so that you may be seen by a doctor who closely matches your needs. Our office manager can also help with any difficult questions you may have.

We take most PPO's and Medicare. We also see patients with HMO insurance through SCCIPA (Santa Clara County IPA) and PMG (Physicians Medical Group of San Jose). If you have HMO insurance, a referral from your primary care doctor is needed before your visit.

If you have called and made an appointment, Privacy and Registration forms are available on the "Patient Forms" tab above. For your convenience, they can be downloaded and filled out prior to your visit.

We value our interaction with you from your very first call! You will be greeted by a friendly receptionist, who will do her best to help you and schedule your appointments. She will tell you about what drugs need to be withheld if skin testing is needed (for more information, click the "Skin Testing" tab above). She will also go over your insurance coverage with you. We try to avoid using answering machines except sometimes on the Chinese language line or on the billing line when specific persons are not available at the moment.

Our office staff work hard to make your visit as pleasant as possible by scheduling convenient appointments, fitting in emergency visits, and keeping us on time while greeting you with a smile.



If you have an allergy, we can help you!

An allergy is a “hypersensitivity” or harmful reaction to substances that are not normally harmful to us. Common allergens include pollens, house dust mites, furry pets and molds. Foods, drugs and chemicals in cosmetics and common house-hold products can also cause allergies. For instance:

Do you have itchy eyes, sneezing, runny nose, and stuffy nose in the spring or fall seasons, or all year round? Do you have a "chronic cold" that has lasted for months? Are you suffering from sinus headache day after day, or a cough never goes away? Are you unable to smell your favorite perfume?

Is your asthma preventing you from playing sports or petting your dog? Do you wake up at night because of cough or wheezing? Have you ever developed hives and don’t know what is causing them?

Is your baby suffering from an itchy rash and you don’t know what to do? Is your child’s school performance suffering because of a runny, stuffy nose, or a chronic rash that keeps him or her from concentrating in class?

These are all common presentations of allergies!

So, if you suspect you might have an allergy such as, allergic rhinitis, asthma, sinus infections, eczema or urticaria (hives), or an allergy to a food, medication, or cosmetics, we can probably help you! We will help you to make the accurate diagnosis and provide you with the proper treatment you need.
