Patient Testimonials

★★★★★

“ONE OF THE BEST DOCTORS OFFICES I HAVE BEEN TO!”

“I've been going to Modena for allergy shots for almost a year now. The staff has been amazing - they are pleasant and make the experience as easy as possible. My appointments have always run on time, and the couple of times I've needed to reschedule, it's been no problem. The office is tidy, and the practice is super organized - no one enjoys shots, but this is as good as it gets!”

— S.S., allergy shot patient.

“If you're an allergy and/or asthma sufferer, I can't say enough about my experience with Dr. Modena and the entire staff. Dr. Modena was very thorough, explained everything in the direction we would be going for treatment, and had all the things I would need ready to go. Sometimes, a doctor visit can be unnerving, but this was anything but that. I felt welcomed, and, to be honest, had a pretty fun time. The best part, I feel so much better than I did a week ago. Love this place!!!”

–W.B., allergy and asthma patient.

“I am really pleased with the attention; the staff at the front office is very attentive, and the doctor listened to me and explained everything very carefully and dedicated. It is a very nice environment. It was really easy to get an appointment, and once I was there, they took care of me very soon. I have to wait no more than 5 minutes to be seen.”

–M.M., allergy and asthma patient.

“I love that I can do something about my allergies long term!! Nice and helpful staff who answer all my questions. It’s also very flexible schedule-wise to get regular allergy shots since I can show up anytime during business hours.”

–A., allergy patient.

“I’m grateful for the time spent with me, time far above my expectations for a doctor visit that, in my experience, usually is a brisk 15 minutes and then done. Here, an in-depth interview was performed, and time was taken to speak on a personal level about concerns and possibilities. It was a very positive experience.”

–R.B., San Diego, CA, allergy and asthma 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.”

–L.S., allergy and asthma patient.

“Dr. Hill is the best around. Her bedside manner is fantastic and I feel like she genuinely cares about curing you. I’ve been coming to for over a year for allergy shots and it has always been a pleasant experience. Her new office is stunning. Mike always has the warmest welcome and fantastic to schedule with. You rarely get great reception teams in a doctors setting so it’s such a breath of fresh air. Seriously one of the best doctors offices I have been to!”

- J.T.

“The staff at this clinic are incredibly friendly, kind, and patient. From the moment I walk in, I always feel welcomed and cared for. My provider, Dr. Hill, is extremely knowledgeable and takes an exceptional amount of time with me, working diligently to find the root cause of my concerns. I truly appreciate her dedication and thoroughness—she goes above and beyond to ensure I feel heard and supported. Highly recommend!”

- T.C.

“Great service all around!! Michael that works in the front is the very best! I transferred from another clinic in NC and I couldn’t be happier with the results. When I get my shots, they do their best to make you feel comfortable and that you don’t feel a thing!”

- V.D.

Under the direction of Dr. Modena, our team ensures that patients of all ages have access to exceptional care and ongoing support.

Modena Health care-team profiles describe each clinician’s published role, background, clinical interests, and associated offices. Treatment recommendations remain individualized and depend on the patient’s diagnosis, history, goals, and response to care.

food allergies One Step at a Time

Oral Immunotherapy (OIT) for Pediatric Patients

Food allergy care requires an individualized assessment. Depending on diagnosis, clinical history, goals, and medical suitability, a clinician may discuss oral immunotherapy, sublingual immunotherapy, other management options, or continued avoidance with an emergency plan.

OIT involves gradually introducing small amounts of the allergen under strict medical supervision. By gradually increasing exposure, OIT aims to desensitize the immune system, allowing individuals to gradually review care goals to the allergen. For qualified patients, OIT may support day-to-day planning for food allergy care. With our experienced allergist San Diego patients are carefully evaluated to determine if OIT is the right choice. We prioritize patient safety and provide close monitoring throughout the OIT journey. Through regular appointments and ongoing support, we empower patients to understand their condition and manage their food allergies with confidence. Schedule a consultation today to see if food allergy might be the immunotherapy solution you’ve been seeking.

Embrace Food Freedom

Specialists in Food Desensitization

Food allergy desensitization is a medically supervised treatment that uses measured allergen doses. For an eligible patient, the treatment goal may be to increase the reaction threshold while dosing continues. It is not a cure, reactions can occur, and ongoing dosing, safety planning, and follow-up may be required.

Transforming Asthma Care

Asthma Testing and Treatment

Asthma has no cure, but it can often be managed with an individualized plan. Chest tightness, wheezing, shortness of breath, or recurrent cough may warrant evaluation because several conditions can cause similar symptoms. Asthma testing and treatment depend on clinical history, examination, lung-function testing when appropriate, severity, triggers, and response to therapy.

Overcoming Inhalant Allergies

Inhalant Allergy Desensitization

Allergen immunotherapy uses controlled allergen exposure over time and may be considered for selected patients with clinically relevant environmental allergy. The clinician reviews diagnosis, expected benefit, duration, alternatives, and the possibility of local or systemic reactions before treatment.

Finding Answers

Skin Testing

Allergy skin testing, including skin-prick testing, may evaluate selected environmental or food allergens when the clinical history supports it. A positive result shows sensitization but does not by itself prove that an allergen causes symptoms; the clinician interprets results with the history, examination, and test controls.

Uncover Your Skin’s Sensitivities

Patch Testing

Patch testing may help evaluate delayed contact allergy to selected substances. Results must be interpreted with the timing and location of the rash because a positive reaction does not always establish clinical relevance. When relevant, the care plan may include practical avoidance guidance and follow-up.

Unlock the Secrets of Your Immune System

Immunology Testing

Recurrent or unusual infections can have many causes and require careful evaluation. When clinically indicated, an allergy and immunology clinician may review infection history, prior records, medications, family history, and laboratory results before recommending additional testing or a management plan.
