Services
Allergy Testing
We offer comprehensive allergy testing to identify specific triggers for allergic reactions. Our diagnostic services include skin prick testing and blood testing for both pediatric and adult patients. Our board-certified allergists interpret test results to develop personalized treatment plans targeting your specific allergens.
Immunotherapy
Our immunotherapy treatments help build long-term tolerance to allergens through customized allergy shot regimens. This evidence-based approach addresses the root cause of allergies rather than just managing symptoms. Our providers monitor progress and adjust treatment plans as needed.
Asthma Management
We provide comprehensive asthma diagnosis and management for patients of all ages. Our approach combines pulmonary function testing with personalized treatment plans that may include inhaler therapy, trigger avoidance strategies, and emergency action plans to control asthma symptoms effectively.
Pediatric Allergy Care
Our specialists offer child-friendly allergy care with testing and treatment options tailored for young patients. We address common pediatric conditions like food allergies, eczema, and seasonal allergies while providing parental education about managing childhood allergic diseases.
Allergy Injections
We administer regular allergy injections following personalized immunotherapy schedules. Our clinics maintain strict safety protocols for injection administration with trained staff monitoring patients post-treatment. Injection hours are available multiple days per week at various locations.

The doctors, nurses and everyone who works in the offices are fantastic. I've been seen in Ithaca and Fayetteville and in both locations I have felt welcomed and have gotten treated great. At least one member of the billing team I have not had a great experience with. She called me in regards to a past due balance. I stated that I did not receive a bill in the mail, but I would happily pay it. She confirmed my address with me and then acted like I purposely was avoiding the bill, stating multiple times "You have to pay it!" while raising her voice.

I hung up the phone feeling shaken and very upset. I receive daily e-mails from the post office with a photo of every piece of mail I will receive that day. I looked all the way through April and there was not a single bill from Asthma & Allergy Associates. I understand that she was just doing her job, but the way I was treated was extremely unprofessional.

I can't say enough about this office. I seriously owe Dr. Flannigan SO much. 10 minutes into talking to this man, and he was able to find a solution to live life in a more happy with less breathing and allergy problems. Taking xolair shots here has 100% changed my life! The nurse practitioners are absolutely amazing and kind, and I'd like to think we have a good rapport with them. I'm always greeted by the nurses and reception, which is great in a world where people aren't concerned with providing customer service. I would HIGHLY recommend going to asthma and allergy!

As a first time patient the staff was very friendly and professional. It took less than ten minutes from the time I got checked in to the time I got in a room with the nurse. I personally worked with Dr. Mariah Pieretti. She is very friendly, listens to anything you have to say and always asks if you have any questions after explaining certain criteria to you. She is willing to help get to the bottom cause of your concerns. I feel comfortable at this office and would recommend them to people I know.
