Dr. Stephen Wong's Testimonials

"Been coming here for over a year now to treat my allergies and it has been a great experience. Not only is Dr. Wong a wonderful and caring doctor but his team is also very caring and understanding. They are very inclusive here and have multiple employees that are bilingual, Mandarin, Cantonese, Spanish, and Vietnamese are just some I know they speak!

As someone that came in with severe allergies and asthma that was left untreated, Dr. Wong was able to help me figure out what I need to be doing to manage them. I also got an allergy test done here, which no surprise I'm allergic to almost everything. So I am currently taking allergy shots on a weekly basis but will slow down the shots eventually. All the employees I see are very friendly and more than willing to help! Brian has been here for awhile and is really such a nice guy! I definitely recommend to friends to come here and get a allergy test to figure out what they are allergic to! It has truly changed my life coming here!"

"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 who is detail-oriented, proactive, 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!"

"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, I'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.

Ready to See an Allergist?

(If you're here, you probably are!)

Before making major changes because of suspected allergies, consider an evaluation with an allergist. Clinical history and targeted testing may clarify whether an allergen is relevant and help patients avoid decisions based only on assumptions or unvalidated tests.

Food allergy evaluation uses the reaction history and targeted testing, with a supervised food challenge when appropriate. For a diagnosed allergy, the clinician can discuss avoidance, prescribed epinephrine, and an emergency action plan. No evaluation or treatment removes all risk.

An allergist can evaluate a suspected food allergy using the reaction history and targeted testing, with a supervised food challenge when appropriate. Accurate diagnosis, avoidance guidance, prescribed epinephrine when indicated, and an emergency action plan can support risk reduction and readiness, but cannot remove all risk.

Recurrent sinus or infection concerns require an individualized assessment. The care team can review patterns, prior treatment, and relevant results, then explain whether additional testing, medical management, referral, or monitoring is appropriate.

Make the Pattern Easier to See

What makes an allergy or asthma history clinically useful?

The most useful history shows what repeatedly happens before, during, and after symptoms. Include dates, possible exposures, time to onset, severity, treatments used, and recovery. For asthma, note nighttime symptoms, exercise limits, rescue-inhaler use, and urgent visits. For recurrent infections, list the diagnosis, organism when known, treatment, and response rather than only the number of illnesses.

Bring records from primary care, emergency visits, schools, and prior specialists to the South Santa Anita Street office when they relate to the current question. A short summary can help the clinician find the important details quickly. Before a testing appointment, ask whether medicine changes or authorization are required and how long the visit may take.

What should I bring to the appointment?

  • a one-page summary of the symptom pattern
  • emergency, school, primary-care, and specialist records
  • medicines, inhalers, epinephrine, and prior test reports

This information supports an efficient visit but does not replace the clinician’s individual assessment.

Planning Questions

San Gabriel Valley Office FAQ

Appointments and insurance

Calling or submitting an online request does not create a confirmed appointment. The office can verify scheduling, referral or authorization requirements, current insurance participation, preparation instructions, and whether a specific service is provided at this location. Benefits and patient responsibility vary by plan and are determined by the insurer; scheduling does not guarantee coverage.

Emergency symptoms cannot wait for an office reply

Call 911 for severe trouble breathing, blue or gray lips, throat or tongue swelling, fainting, confusion, rapidly worsening symptoms, or suspected anaphylaxis. Follow the patient’s prescribed emergency action plan and use prescribed epinephrine when directed. Do not wait for a clinic callback during a medical emergency.
