Precautions We're Taking Regarding the COVID-19 Virus:

We are very concerned with the health and safety of our students, employees and partners with the spread of the novel coronavirus.   
Here are some actions we are taking: 

1) In our training areas, commonly touched surfaces are sanitized before and after each class.

2) We have hand sanitizer available for use during our classes.


3) Following guidelines and recommendations of the CDC, we encourage thorough washing of hands of all employees and students and to limit contact with their faces.


4) Our classrooms are of a good size and class attendance will be kept intentionally small to allow more social distancing between students.


5) In our facilities, we ask that any coughing or sneezing be done in an elbow or in a tissue. When done into a tissue, the tissue should be immediately discarded and hands washed thoroughly or sanitized.


6) If a student has recently visited any of the affected countries/areas or possibly been exposed to the virus through any means, whether there are visible symptoms or not,  we respectfully ask that you postpone your class until after you have recovered. We welcome you back at a future class.
