 UPDATED COVID-19 Information for our patients and families               

Our new office scheduling dynamics are working great!  Well visits and non-contagious visits such as pre op exams, ADHD/behavioral evaluations, and vaccine only visits are being done in the morning or very early afternoons.  All sick visits with ill symptoms are being seen in their cars, so you have no exposure to others contagious illness.  Our patients are loving it!  We are offering telehealth visits with our providers this week starting this Wed afternoon.  Please call for details on what your platform is (Skype or Facetime) and to see if your child is a candidate for this type of visit.  We are all in this together and we will get through this together.....     

JK Peds is here for your well and sick needs. We are changing some things during the COVID-19 outbreak: Our priority is to keep our patients and staff healthy and protected during this outbreak:

Well visits/other routine visits

1. Our front door will be locked to avoid any unannounced walk in sick visit to protect our well patients and staff

2. Please call our office once you arrive for your appointment

3. Please come to the visit with one parent/family member, and no siblings if at all possible

4. Well visits will complete their paperwork in their cars then will be brought into a “well visit only” room for their exam and vaccines.

5. Non-contagious visits such as ADHD checks, ear rechecks, vaccine only visits, ankle sprains can also be seen at designated times so they are not exposed to any illness.

6. A mask is required for anyone entering the office. 


Ill visits

1. Call our office before bringing your child in – our front door will remain locked to walk ins

2. We are screening all callers with questionnaires before bringing them into our office

3. We are offering telephone provider visits that can be billed to your insurance

4. We are seeing our ill patients in their cars and can obtain vitals, testing for RSV, flu, strep, and examine patients in their cars when possible. Please wear a mask!!
