I have seen him 3 times (for an immune deficiency). The first appointment I was called back quickly, the 2nd one I waited over an hour, and the 3rd time was about 30 minutes. But even the time I had to wait over an hour I got that time back with him as he was not in a hurry to push me out the door to get to the next patient so I am presuming that the patient's in front of me needed him and his time as badly as I did so I don't mind waiting if I get that time back when it's my turn. My only complaint is with the office, if you need to get a message to him or have office staff call you back it is impossible. I was having a rather urgent matter and left a message for the receptionist (only option for my issue) and left 3 messages and never did get a call back, and then I had another matter that, prior to my appointment, I needed an answer, left another message with receptionist and never got a call back. I'll be the 1st to admit a receptionist is going to be incredibly busy, so they need to have another staff member that just goes through and checks for voicemails and does those call backs.

I have Ehlers-Danlos syndrome and I have been having autoimmune issues for years and one Dr would tell me no I think it is this, go see this doctor and that took place 7 or 8 times over a 5 year period. Then... I was referred to Dr. Khan. She sat and reviewed my records and sent me to see a hematologist to rule out one of the differential diagnosis that she had in mind. Once that was ruled out she began a plan of attack to help get my immune system in check. It has been a day and night diffence to my health since I met with her 2 years ago. I couldn't ask for a better doctor. She sat and listened to every concern I had and rather than looking at one symptom she looked at all of them and saw the big picture! Thanks Dr. Khan

About Allergy, Asthma, & Immunology Associates

Allergy, Asthma & Immunology Associates is a specialized medical practice that helps people of all ages overcome challenging symptoms and return to an active life. At our offices in Tampa and Brandon, Florida, our board-certified physicians, nurse practitioners, and staff warmly welcome each person, taking the time to connect and learn about their concerns.

As a full-service practice, Allergy, Asthma & Immunology Associates providers diagnose and treat all types of allergic conditions, including hay fever, asthma, chronic cough, and food and insect allergies. Our comprehensive care includes allergy testing, shots, and allergy prevention recommendations.

The team also cares for a wide range of allergy-related conditions and symptoms in multiple organ systems. Patients frequently seek the team’s expertise when they need treatment for skin problems like contact dermatitis and hives and respiratory conditions like asthma, nasal congestion, and sinus infections.

Immunodeficiency diseases are especially challenging for patients as they face repeated infections. The team has extensive experience managing these disorders with advanced treatments that strengthen the immune system and restore health.

Allergic patients are often affected by multiple allergic conditions at the same time, such as allergic rhinitis, asthma, and eczema. Their symptoms are sometimes made worse by other underlying conditions such as chronic sinusitis, acid reflux, and immune deficiency. It is important to seek help from a board-certified allergist who has the expertise to evaluate and treat all these conditions in order to achieve the best results.

At Allergy, Asthma & Immunology Associates, our physicians and staff pride themselves on providing state-of-the-art medical care while treating patients with compassion and respect.
