Ling was an awesome instructor, I learned so much from her when I took my CPR/ BLS class on 8/8/15. She is very thorough with her teaching and her class was very entertaining, never a boring or dull moment! You can tell Ling is very passionate and knowledgeable with the class content. I would recommend her class to all my friends and family that needs to get certified with CPR/ BLS. Thanks for a great class!
