During this public health emergency, Timber Lane Allergy and Asthma Associates is restricting in person visits to our office to those patients who need essential services that cannot be provided otherwise. No one should come to the office who has had a fever within 14 days, symptoms of a common cold, cough, current respiratory illness, or significant exposure to an individual with confirmed COVID19. If you do come to the office please respect social distancing guidelines, proper handwashing, minimize contact with office surfaces and wear a mask or face covering. We will enforce measures to allow safe distancing.

We are now offering telemedicine to allow us to continue to provide patient care as well as minimal in-office visits as needed effective June 1st. Please see FAQ for further information. These recommendations will be modified as the circumstances change.

COVID-19 Virus Information and Action

The health and safety of our patients and staff is our number one priority. To reduce exposure to all, we have initiated the following changes to our practice:

Effective immediately, all injections will be need to be scheduled as we have removed our walk-in hours. Lab hours remain 8:00am-3:45pm Monday and Wednesday’s and 8:00am-4:45pm Tuesday and Thursday’s. We understand how valuable your time is and we expect this change will reduce waiting time. Our new schedule will allow plenty of appointments and there will continue to be no charge to you if an injection appointment is cancelled or missed. We are happy to answer any questions you may have about this change.

  • Anyone with a recent or current fever, symptoms of an upper respiratory infection (such as cold, cough) within the last 2 weeks should not come into the office. Please call us if you have any questions.
  • We ask that only the patient come for their appointment and 1 guardian/caretaker if needed. Additional family will be asked to wait in their vehicle or outside to ensure proper distancing practices.
  • If you need a refill, please call our office and we may be able to make accommodations which eliminate the need to come into the office.
  • You will be roomed as soon as possible upon arriving for your appointment and we encourage our patients to distance themselves if they are in the waiting room.
  • Everyone entering the office must hand sanitize, wear a mask or face covering, and have their temperature taken with a touch-free thermometer. We will have sanitizer at our entry for your convenience.
