• From Zhenning, Isaac’s father: “Hi Coach Mario… Just want to let you now that Isaac (12 years old) finally passed 2200 (master) in rating last night (4/2022) after the club championship. This would not have been possible without you being his first coach. Really appreciate your teaching. Again, really appreciate you for building Isaac a solid foundation in chess, I can see that is one of the main differentiators of Isaac against many other kids. Best Regards…He told me he learned a lot from your lesson so that he recognized all the techniques his opponents tried to use on him.  I can see he’s built more confidence and interest in chess after today’s winning. It was a very good experience for both of us.  I am very grateful for the teaching, guidance and help you have given…how fantastic you are as his first coach. You helped him build up a very solid foundation in chess play in two years time…You are very good at communicating and your teaching is well organized, I can’t imagine him reaches his level without your coaching in two years… He is very picky in who he wants to pay attention to.  He usually lost focus to me or my wife after 40 secs or so.  He still has a lot to learn from you, not just chess strategy but also life experience. I think you are very good at teaching chess: sometimes (my son) explains a bad move I made when playing against him… I can see it must have made crystal clear sense to him.  In my opinion teaching skill is more important than personal achievement as a coach.  I am very happy with the progress he has been making under your coaching. My wife and I are very grateful for the help you have given him.  I have also recommended you to some of my friends who have kids interested in chess…I will probably still consult you on his chess in the future.  You have given him tremendous help and he won’t reach his level today without your coaching.”

• From a parent: “Hi, Mario…You are a great coach: very patient, encouraging and responsible. Her chess has improved a lot. She has also learned something beyond chess, such as general attitude toward things, from you. Thanks and congratulations!” -2009; Seven years later she wrote: “Benefit from her chess experience and also your help over the years, she has got into Princeton early action.” -Jan. 2017 (note: she eventually chose Harvard)
• From a parent: “…truly encouraging!…(they) can’t stop smiling.” -March 2016″; It was a desperate decision for me to consider chess when they were bringing home failing grades… It’s as if I’d hit the jackpot. Their grades are improving and they are way more confident. Thank you for what you do.” -May 2016; A year after moving to the east coast: “Thank you for being there for them.” -Oct 2018; “Thank you for all that you do!” -May 2019

• Very first one-on-one student (1999-2001) graduated Yale class of 2014.
• From a parent: “Mario…Thanks again for all you do for her – above and beyond pure chess.  You have a great balance of encouraging her, letting her be a little kid (to a degree), but also pushing her, treating her like an adult, teaching her very profound concepts that will help her in all aspects of life in the future.”-2017
• From a parent: “Mario, Rob has worked two years longer… to achieve his diploma. You were one of the people who believed in him, even when I thought it was impossible. We are all so proud of Rob, but most importantly he is proud of himself. Just wanted to thank you. Chess was pivotal in changing how people viewed Rob. When he became the ‘chess kid’, it changed his whole trajectory.” -June 2021
• From a high school student: “Thank you so much for teaching me not only chess but also lots of life lessons. I really appreciate how understanding and patient you were, and especially how encouraging you were. I would always come out of chess lessons feelings as if I actually accomplished something, that I understood something that I didn’t before. You have always inspired me to do my best and also think about what’s really important to me. I, one day, also want a dream just like how you discovered chess.” -2021
