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.”  

Nurse Practitioner Jill Curren

"I have been in the medical field for more than 30 years and have always felt it was the right career path for me.  Being able to treat the whole person—body, mind and spirit as well as considering the whole family is the true calling of a Nurse Practitioner. I also understand the misery that allergies create from my own personal experience; because allergy shots worked for me, I now have my own dogs and cats and volunteer in an animal shelter. I really love patient interaction and getting to know Sher Allergy Specialists' patients and their families. Being able to help people is truly a gift that I enjoy doing."
