Dr. Mandel R. Sher

“Every person is like a snowflake – uniquely different from head to toe!  I meet each child, teen, adult, and family where they ‘are’, with a safe and effective solution to their worrisome and potentially dangerous allergies and asthma. I am board-certified in Adult and Pediatric Allergy and Immunology, in addition to Pediatrics and trained at Northwestern, Duke, Harvard, and University of Michigan. I write, lecture, research, teach, and advocate on allergy and asthma care too. I have dedicated my professional life to allergy and the people behind the sneeze, cough, rash, and runny noses whose lives I change.”

Dr. Johana Castro Wagner

“Allergic disorders are unpredictable and affect all age groups and races with no discrimination. These could be very disruptive in the lives of people, especially children, causing tremendous anxiety for their caregivers. I have committed my life to helping those whose lives are affected by such allergic disorders and strive to make a difference to them. It is a very exciting time in the field of allergy and immunology as we continue to develop ways to treat diseases we could not treat before. My patients know I make communication a priority and when they come to see me they will leave knowing what we are treating and how we are going to achieve success.”  


P.A Lynette Jubay

"I have always reiterated to my patients that you have to live in your body for the rest of your life, so you better take care of it.

Allergy and immunology encompasses so many diseases or disorders that can be life-changing for an individual when stabilized and treated properly. I feel so blessed to be a part of a team that can help people truly enjoy and live life to the fullest!"

Patient Reviews

Lori's Story

“I was getting sinus infections and ear infections every couple of months. Dr. Sher fixed me right up. Started me on injections which I had bad reactions to. He tweaked and came up with a very slow but workable schedule and I have never felt better. When I proved to be a challenge he didn't give up. He tried and tried until he got it right and that is what I love the best. He didn't treat me like a one size fits all patient. I love (almost) never being sick!”
