What Educators Say
"Ms.Vaishali Gupta has tremendous ideas that help in aiding educational institutions, which in turn make our country better. She acquires thorough knowledge before she takes up any assignment. She is highly resourceful and her presentations are very inspiring, informative and educative. Thank you."
"One teacher, One Scientist" is indeed a fantastic concept of Ms. Vaishali Gupta! Our country with 130 crore population certainly needs scientists and having the largest number of worlds youngest population it is indeed imperative that we look for inspiring teachers! I had the good fortune of sharing the Dias with Ms. Gupta and could sense her passion for science teaching and particularly demonstrating to teachers how to use STEAM based activities for students! I wish her all the very best for this endeavour of hers!"
"The pristine Guru in madam Vaishali has effloresced into the books that she has authored"
