Welcome Dr. Kaplan, Dr. McMurtry and Allergy & Asthma Consultants!

We are excited to announce that as of October 3rd, Allergy & Asthma Consultants (AAC) has joined Family Allergy & Asthma. AAC’s two offices – located in Gurnee and Libertyville – will be Family Allergy’s first offices in Illinois. Both practices share common core values, and the merger will allow AAC to continue to focus on excellent patient care and customer service.

What does this mean for current Allergy & Asthma Consultants patients?

Although their name will be new, the providers and staff will remain the same, as will their focus on delivering the highest quality care to patients. Dr. Mark Kaplan, Dr. Stacie McMurtry, and physician assistant Sandra Denman, will see patients in both the Gurnee and Libertyville offices. Any visits before the merger will be billed from Allergy & Asthma Consultants and any visits afterward from Family Allergy; this means you may receive a statement from both companies in the same month, depending on the date of your visits. In addition, patients will now have access to an online patient portal, which includes appointment requests, bill pay, medical records, and more. Thank you for your patience as we transition to an electronic medical records platform.
