I'm really enjoying the way CJ teaches. It's making learning the hard stuff so much easier.

Thank you for always staying on top everything! I really appreciate having you through all of these sessions! It’s been a fun experience learning about optical with you. I think you’re totally awesome with your full energy and sharing your knowledge to each and everyone of your students!

Best class I’ve ever taken!! CJ really makes the optical world so understandable and down to earth! Do yourself a favor and sign up for his classes!

CJ is an amazing instructor! When he calls himself an optical nerd he means it. He is so excited and enthusiastic about the material he is teaching that you get excited too. I have been in optics over five years and the way he explained things to me finally made them click! The classes have a great layout and were a lot of fun, the daily quizzes really lock in the information. You cannot go wrong by studying with Optical Nerd!

After failing the ABO twice I decided to give it one more chance but this time having CJ as my tutor, He’s amazing very knowledgeable and down to earth. The way he explain everything, he makes it so simple! He’s awesome. What are you waiting for?? Sign up for your ABO and be successful in the optical world!

CJ is amazing. The class was very informative and so easy to follow. CJ accommodates for all learning styles.He is also very knowledgeable on what things will be on the ABO along with common mistakes to try and avoid.

Thank you so much CJ! I'm truly enjoying the letting process you are starting with us. I've learned so much in just these couple of sessions and I've been in optical for 25 years. I do want you to know that you are a great teacher and I'm grateful for this opportunity to grow in the field.
