"While donating clothing items at Green Drop in Bethesda I noticed a mobile site that offered PCR testing for COVID. I've had my two shots and booster and aware of the various strains out there so I decided to get tested. I pulled up to the area outside the mobile building and honked the horn as instructed on a sign outside and a moment later IVO NGONG came out and asked if I had an appointment, I didn't but didn't realize I did. IVO advised me to make an appointment using my mobile phone and once done he could perform the test. I'm technically challenged using my mobile only for talking and texting, so IVO made the appointment for me and moments later I was on my way. I didn't know what to expect, but the last thing I thought would be that of a medical technician standing outside in 90 plus degree temperature making an appointment for me. What a patient and extremely helpful man. I must have thanked him a dozen times. Simply said, what a great experience. Thank you again Mr. IVO NGONG."
