Last Sunday we had two great guest speakers at my "Shelley's Show & Tell".

A registered respiratory therapist filled us in about oxygen and oxygen machines. We didn't film it so I am going to put together some questions for him and we will make a video  of our conversation...it was so interesting and informative!!

Then the CEO of Celluma spoke to us about LED technology, NASA and FDA clearances. It was super insightful. We did film it, so I'm hoping to get it on my website soon. Watch for it!
