About Family Allergy & Asthma Care
Caring for you just like we care for our own family.
We’ve brought peace of mind to families for over 25 years. Our friendly, caring team helps both adults and kids find relief from stressful food allergies, bothersome environmental allergies, and debilitating asthma.
Being moms and caring for our own families has given us a deeper understanding of how to care for you and your family. We understand the need for early morning and evening clinic hours, educational resources, a listening ear, and a caring heart. As board-certified allergists we have completed the highest level of training in allergies, asthma, and immunology which allows us to offer you expert care. We’re your devoted partners in solving your healthcare needs.
MEET OUR DOCTORS
Fellowship-trained, board-certified allergists. And, we’re also moms.

“One of my children has a food allergy and so I understand these challenges firsthand. I live with it day-to-day and I didn’t just learn about it in a textbook. It fundamentally changes so much for families including sleepovers, parties, and school. We want to partner with our patients so they not only receive treatment like desensitization and immunotherapy, but also education and guidance on lifestyle changes.”Diplomate: American Board of Allergy & Immunology 1995- Present

SMRIDHI (SIMI) MAHAJAN, MD – DABAI
“I provide comprehensive care for the full spectrum of allergic, asthmatic, and immunologic conditions. While I treat all aspects of allergy and immunology, I have particular clinical interests in asthma management, environmental allergies, and drug allergy evaluation and delabeling. There’s something particularly satisfying about safely removing outdated or incorrect medication allergy labels—it’s like unlocking doors to better treatment possibilities that may have been closed for years. I love being the detective who helps solve these medical mysteries with you. ”Pediatric Residency: University of Texas Southwestern Medical Center / Children’s Medical Center, attended from June 2020 to June 2023
