About Dr. Maaz Mohiuddin
Providing relief to patients who have struggled with allergic disease is what drives me to be at the forefront of our field. I earned my Doctor of Medicine from the Medical College of Wisconsin, completed my residency in Pediatrics at the Children's Hospital of Wisconsin, and pursued a fellowship in Allergy and Immunology at National Jewish Health. There, I trained in an environment where we saw the most challenging cases of atopic dermatitis (eczema), asthma, food allergies, and other allergic conditions in patients from all around the world. I was mentored by world-renowned allergists at National Jewish Health, who have written many of the guidelines we follow today. Despite being surrounded by the most advanced diagnostics and minds, I learned that spending time with patients-educating them about their disease and treatments, and ensuring proper technique-is what most often leads to drastic improvements in their quality of life. My goal is that every patient leaves our office feeling empowered and involved in the decision-making process of their health, with no questions unanswered. I especially look forward to treating the most challenging cases in patients who have suffered too long with no relief despite multiple doctor visits.

i waited 30 minutes after my appointment time to be brought back to his office? not even an exam room. dr just sat behind his computer taking notes- never once listened to heart or lungs and there for asthma……
after he typed he circled tests on a sheet and sent me on my way.
the office itself was dingy and gross. i will not be going back there ever again. worst allergist ive ever seen.

This was my first visit with this Dr & he was very underwhelmed. I was brought in his office & all he did was sit behind his desk & ask me questions. At no time did he get up to greet me or walk me out. He also didn't exam me at all. This visit was very impersonal & seemed like more of a transaction than a visit with a doctor. I will try visiting this office once more hoping for a better experience.

I confirmed amount due for next appointment would be zero as my deductible as well as out of pocket maximum have both been met at prior appointment and when I showed up today they attempted to charge me. I cancelled and will not be returning.

The appointment seemed very odd to me. The office staff was not friendly or welcoming to my child and the doctor did the entire appointment from behind his desk.

I have an appointment to see him next week
March 24, 2023Bryan W.Verified patient
I booked an appointment with this office on the same day, after having a different provider cancel on me due to them having inaccurate information advertised on ZocDoc. The staff at Allergy Asthma & Sinus Centers was amazing, not only calling to confirm the appointment and offer varying locations beforehand, but even in their care and kindness within the office. You can tell this office has many visitors each time they’re open, but they do not allow heavy traffic/larger numbers to stop them from being patient and considerate. From the front desk administrators to the physician, everyone handled each patient/family efficiently, professionally, and with a smile. Dr. Mohiuddin is extremely knowledgeable in his field, but more than that I can tell he listened carefully to the explanation of my daughter’s needs and responded attentively. Thoroughly enjoyed our experience here. Worth the drive for me!
