Welcome Patients of Dr. Kim Waterhouse to Allergy, Asthma & Food Allergy Centers

Dear Dr. Waterhouse Patients,

We are delighted to welcome you to our practice! We aim to make your transition as smooth as possible. 

If you are on allergy injections, we should have your vials by July. Please download the new patient paperwork from this page and allergy shot treatment consent and financial consent. We do ask that you please email the completed new patient paperwork, consent forms, copies of the front and back of your insurance card, and driver’s license to info@aafacenters.com. Please include in the subject line “transferring Dr. Waterhouse patient”. Please also schedule an in person office visit at your earliest convenience in order to become further established in our practice. You will need to have that visit before we can refill medications and answer medical questions. The first visit will likely be with Lauren Davis, PA-C in the Chesterfield office, but Dr. Waterhouse will resume her role as your primary Allergist after she starts with the practice in late August. 

  • Allergy injections administered in our Chesterfield office (16216 Baxter Rd., Suite 299, Chesterfield, MO 63017):
    •  8:30AM – 4:30PM Mon-Thur
    •  8:30AM – 2:30PM Fri
    • We plan to add late office hours starting Tuesday, August 31, 2021.
  • We follow the guidelines from our professional allergy societies  that all allergy injection patients will need to wait in the office for 30 minutes after their injections.

If you are on a biologic for asthma or hives (ex. Xolair, Fasenra, Nucala, Cinqair, or Dupixent), please call at your earliest convenience to schedule a telemedicine or in person office visit by June 2021. If this is a telemedicine visit, it will be with one of our Advanced Practice Providers (Lauren Davis, PA-C, Laura Kahle, PA-C, or Dani Loftus FNP-BC) so we can get you established as soon as possible. You can read more about telemedicine visits here. This will allow us to get you registered in the practice and enable us to go through the necessary prior authorization process to obtain your medications. When you are due for your injection(s), and we have verified that we have your medication, we will schedule an in person visit in the office. Please note that our policy is that you will need an office visit for each biologic injection administered in the office. New Patient paperwork is available on this page and information on telemedicine visits is available here. Email the completed new patient paperwork, consent forms (if needed), copies of the front and back of your insurance card, and driver’s license to info@aafacenters.com. Please include in the subject line “transferring Dr. Waterhouse patient”.

For all other patients, we request that you please schedule a telemedicine or in person office visit at your earliest convenience to become established in our practice. We will need to see you to get you established in our system so we can refill medications and answer any medical questions. This is also an excellent time to do an annual visit. We can provide updated food allergy and asthma action plans at the time of the visit if needed. New Patient paperwork is available on this page and information on telemedicine visits is available here. Email the completed new patient paperwork, consent forms, copies of the front and back of your insurance card, and driver’s license to info@aafacenters.com. Please include in the subject line “transferring Dr. Waterhouse patient”.

We recommend that you follow us on Facebook, where we post practice updates.

It is our pleasure to play a role in keeping you well. We look forward to meeting you!


Welcome patients of Dr. Esswein to Allergy, Asthma & Food Allergy Centers!

Dear Dr. Esswein Patients,

We are delighted to welcome you to our practice! While we did not anticipate this particularly trying time, we aim to make your transition as smooth as possible. 

If you are on allergy injections, we should now have your vials. Once we have entered your vials into our electronic system and have you registered in the practice, we will call to let you know that you can come for your injections.  Please wait for this call before you come to our office, but in the meantime, please download the new patient paperwork from this page and allergy shot treatment consent and financial consent. Email the completed new patient paperwork, consent forms, copies of the front and back of your insurance card, and driver’s license to info@aascare.com. Please include in the subject line “transferring Dr. Esswein patient”. If you have not received a phone call in the next 1-2 weeks, please call us. Please also schedule a telemedicine visit at your earliest convenience in order to become further established in our practice. You will need to have that visit before we can refill medications and answer medical questions. The first telemedicine visit will be with Dr. Esswein or one of our advanced practice providers (Lauren Davis, PA-C, Laura Kahle, PA-C, or Dani Loftus FNP-BC) so we can get you established as soon as possible. You can read more about telemedicine visits here.

  • Allergy injections are administered:
    •  8:30AM – 4:30PM Mon-Thur
    •  8:30AM – 2:30PM Fri
    • You will notice we have shot hours on Tue evenings (not currently offered during the COVID-19 pandemic) and Sat mornings. We ask that you kindly avoid these times until further notice, as they are typically our busiest times with the longest wait periods. 
  • We follow the guidelines from our professional allergy societies  that all allergy injection patients will need to wait in the office for 30 minutes after their injections.
  • During this time of concern for COVID-19, we will not escalate your dose. This is to help minimize the risk of an adverse reaction, particularly as we are now in the spring season. We will also allow you an extra week “grace period” where you will not be considered late.
