Modena Health Patient Testimonials

"Our daughter has been a patient of the Modena practice for the past year or so and we are incredibly grateful that we found such a wonderful group to help us with her food allergies. When she was 9 months old, we found out that she had an egg allergy and that led us to additional testing which uncovered that she had a cashew/pistachio allergy. We were terrified when we heard this news as we never wanted our daughter to experience any type of severe reaction nor did we want her or us to have to live in fear of these allergies for years to come. Dr. Modena and his team spent a great deal of time providing education on her allergies as well as education on a desensitization program that we could employ if we chose to do so. After much consideration we decided that was the right path for our family.

We are absolutely thrilled with the progress she has made and the results we've achieved under their care. Her blood work numbers have dropped significantly, and we are only a few weeks away from completing her desensitization program for her cashew allergy. We will continue to monitor her allergies with Dr. Modena's team as time goes by, and we are so happy to have someone by our side. We are building up to the point where she will be receiving a monitored dose of a couple of cashews several times a week and that is an absolutely amazing relief. It will be so nice to live with confidence that if she were to have any type of accidental exposure her reaction should be mild or nothing at all. It is an amazing concept to slowly expose your body to what it would see as a danger so you can teach it to not overreact.

Allergies, especially in children, should never be taken lightly and we appreciate the team's conservative and caring approach. What a difference a year has made in our lives with the tools, resources and support we have received."

–SAN DIEGO ALLERGY PATIENT

"Dr. Modena is extremely patient. I have a very complex condition that has no definitive cause. It impacts my daily life, but Dr. Modena has been wonderful about treating the symptoms. I am sure at times he is as frustrated as I am to find an answer and make it go away, but he is always patient. He said 'I never give up on a patient.' It's very comforting to know he is always working to make things better for me. His staff is always friendly and efficient. I highly recommend Dr. Modena."

— MAUREEN D., SAN DIEGO PATIENT

"Dr. Modena is one of a kind and the best doctor we could've asked for to treat our son's food allergy. I had performed a deep dive into the world of child food allergies after finding out our son had a peanut allergy at 5 months old. We were interested in having our son undergo oral immunotherapy for his allergy because the research seems to be positive and growing for this treatment. It was difficult to find a provider that was willing, but we are so thankful we found Dr. Modena as he was extremely knowledgeable and talked with us about the treatment as an option.

One important thing to know about Dr. Modena is that he is excellent when it comes to shared decision making. When we met him, I explained how I had researched oral immunotherapy and our interest in seeking treatment for our child. He provided his own expertise and invested time and energy to further delve into the research on OIT for young children. We then consulted further and he was willing to do the treatment, laying out options, risks/benefits, and explaining what the OIT treatment would be like. It really feels like a team effort during our consults and he is very forthright with information that we need to know, explaining things thoroughly We were thankful that Dr. Modena was willing to work with us to provide the OIT treatment for our son. He is truly an amazing doctor that is detail-oriented, proactive, and and acts with a patient-centered focus. His staff are also kind and courteous. If you are interested in seeking oral immunotherapy treatment or similar options for yourself or your child (beyond the traditional avoidance model), then Dr. Modena and his staff will be able to help!"

— LAUREN MIGNEA

"I went to Dr. Modena after my allergist Dr. Jaffer retired and Dr. Modena took the practice over from him. I was having a breathing problem and found that Dr. Modena is extremely caring and thorough. He listens, does not rush patients, and called me to follow up the following week... Thank you, Dr. Modena!"

- ALYSSA S., SAN DIEGO ALLERGY PATIENT

"My first allergist! An amazing Dr. He takes the time with you that a lot of doctors won't anymore. As far as results, l'm doing 200% better than I was before I started seeing him."

- MC, LAKESIDE ALLERGY PATIENT

“Dr. Modena and his staff are great. I immediately felt welcome and HEARD when just booking the appointment. … The rooms were clean and comfortable. This was all before I even met Dr Modena! He continued the vibe of calm understanding, and I felt confident telling my story to someone who seemed like he not only believed me but wanted to help. We haven't started treatment yet, but his plan is solid, and he made sure I understood the different avenues it could take. One of the best medical offices I've been to.”

–S.B., allergy and asthma patient.

“Modena Allergy and Asthma provides excellent service. The office is beautiful and peaceful. The check-in process was smooth and pleasant. I was seen on time. Samantha was kind and thorough. I highly recommend them.”

Do You Have Allergies?

When to see an allergist

Don't let allergies or asthma control your life. Consulting with an allergist can save you from unnecessary stress and expense. Before making drastic decisions (like rehoming a pet or moving), visit an allergist to pinpoint the real cause of your symptoms and develop a tailored action plan.

Skip the costly at-home tests. An allergist can help you interpret results and decide on dietary changes without eliminating foods you enjoy unnecessarily. To prevent severe allergic reactions, seek professional guidance.

An allergist provides accurate diagnoses, advice on avoidance, and effective treatment plans. Don't endure recurring sinus infections; explore innovative, non-surgical treatments with an expert's help.

Act early to tackle allergies with confidence. Meeting an allergist sooner can help you sidestep severe reactions and find the right solutions. At Modena Allergy, our expert team of providers are ready to provide precise answers and a tailored, data-driven plan. This approach helps avoid the frustration of trial and error and ensures safety for you or your loved ones. Discover how to accurately identify food allergies, effectively manage them, and learn rapid response techniques for anaphylaxis—all crucial steps in maintaining your health without unnecessary risks.

Don't let persistent sinus infections disrupt your life. Consult an allergist to explore non-surgical treatments and uncover possible immune system issues. It’s wise to seek expert advice sooner rather than later for these concerns. Dr. Ziering and the team are here to provide clear answers and create a personalized, data-driven plan that delivers tangible results—without the hassle of trial and error.
