Here is a sampling of Emails, text messages, and cards I've received from students (and parents) over the years.

Yes, it's good social proof that I know what I'm doing, but more importantly, it reassures me that my life hasn't been a total waste of time. I'm doing something meaningful and have made a difference for a lot of people along the way; as I keep getting older, this means more and more to me.

Additionally, you can read evaluations I received from students while teaching at Harvard here.

Thank you, Eddie! K truly enjoyed learning from you. She bubbled with excitement each week after her sessions with you. You gave her such a gift—the joy of learning something deeply from someone who loves it, knows it well, and understands how to share that knowledge. She’s going to miss working with you! Please let us know if you teach any other chemistry topics.

Subject: Orgo I + II Overview


I hope you are doing well and enjoying the end of summer. I was able to finish Organic Chemistry II with an A-, I am extremely happy with this result! The final was long and tricky, but I was able to do well. When I found you last fall, I really thought this may be the end of my veterinary career, having to drop organic chemistry I. But you provided an extreme depth of knowledge in a manner that was organized and concise, which was a true game changer. Those tutor sessions resulted in me getting an A in Organic Chemistry I upon my retake! Your passion for organic chemistry is contagious to the point where I now think about organic chemistry in my everyday life. I thought Organic Chemistry was going to be a weakness on my application, but now it is a strength. Thanks for everything!

All the Best,

Thanks so much for all of your help this past semester. 

update: I ended up with an A in the class! Could not have done it without your help, knowledge, and encouragement. Somehow, I ended the semester way more interested in Organic Chem than I had been prior, which is crazy to think about. You played a large role in that... thanks again!

Have an amazing (and restful) summer.

Hi Eddie! I hope you are doing well and having a good week!

I wanted to let you know that I ended up passing my O-Chem 2 summer class! I can't thank you enough for all your help and everything you've done to help me succeed. I couldn't have passed O-Chem 1 and 2 without you and I am so grateful to have had your help and guidance. I struggled in these classes, but you made concepts so much easier to understand, and all your extra worksheets and handouts were very helpful. You have been so kind and I am very thankful for your help.

In the future, I will be studying to take the DAT and will definitely need help with that, so I will make sure to get in touch with you! Thank you again for everything, you helped make a daunting subject for me so much easier to handle.

Hi Eddie,

I just checked my S-20 grade online, and I got an A for the entire course! I'm absolutely thrilled.

Thank you again for an amazing summer of working together - we did it!! Your creative handouts and simple explanations of complex concepts made mountains of content just "click," and your responsiveness to my (many!) questions showed how much you care about the material and your students.

I feel honored to have learned from an Ochem "Jedi master" like you, and truly feel like your mentorship has forever changed my approach to learning. Thank you for guiding me on this journey.

Wishing you the best, and I hope to keep in touch in the future! If I hear of anyone planning to take Ochem, I will absolutely send them your way.

PS - we haven't found out our exact grade on the final yet, but I'll let you know -- I'm figuring it must've been not too bad 🙂


-Harvard University student summer 2020

Eddie pours his heart into his work. He has created dozens of well-designed, humorously illustrated handouts that explain orgo in a far more accessible way than dry course lecture slides. Although he is an expert in organic chemistry, Eddie speaks in English, not in orgo.

The day before an exam, Eddie treats his students like an anesthesiologist would treat a patient before surgery. He is exceedingly responsive to last minute questions and addresses with a sense of urgency any shaky areas that could make the exam go poorly.

Eddie is the kind of tutor that I imagine Ancient Greeks wanted to send their children to — people who took it as their personal mission to educate their children to the highest degree. Although I am glad to have organic chemistry behind me, I will miss working with Eddie. He will forever exemplify for me what a good teacher is like.

Hi Eddie,

The [final] exam went alright I would say, it's always been hard for me to tell coming out. I would say the mechanisms were different than usual in that they weren't like what the class had "rehearsed" in terms of known reactions and motifs but rather stuff that you had to think a little harder about. I ended up being short on time towards the end, but I tried to get at least somewhere productive with each of the mechanisms. The format was similar to practice tests, with some interesting spins on concepts like EAS. Glad to be able to take a bit of a break from ochem now!

I can't thank you enough for all of your help. Chem really stressed me out at the beginning, and regardless of how the grade ends up, I am so thankful for our sessions that have made me appreciate rather than dread chemistry. Have a great holiday season and look forward to catching up with you after!

Hi Eddie,

Thank you again for your persistent effort in keeping them prepared. You have kept them focused on the material and have continuously encouraged them to meet the challenges.

They just look forward for your classes each week and I can see that your classes and regular communication gave them the confidence to pursue it with passion.

You are doing way more than tutoring and we are really appreciative of that.

We are sure you contributed immensely in many students success in the past.

Happy holidays Eddie! Now that the semester is officially over, I'd like to thank you again for being easily the best TF I have had at Harvard. Without you, I doubt I could have done nearly as well in a class as difficult as this one.

Thanks so much,

Hey Eddie,

How are things now that the semester is over? The final felt like it went really well!! There were a few challenging questions, but nothing we hadn’t seen before. Any who, I wanted to say thank you for all your help this semester. I really appreciated the time and patience you took to teach me all about the concepts of O-Chem. Without you, I wouldn’t have done nearly as well in the course, nor would I have enjoyed it as much. I never expected to like O-Chem, but I think it’s probably one of the coolest subjects I’ve ever taken. Thank you for always being so encouraging and sharing your passion for learning O-Chem, it was truly contagious. It was a real pleasure working with you and getting to know you. I hope to keep in touch 🙂

Happy Holidays!

Hi Eddie,

How are you? Hope all is well. It’s been a while since I last emailed you. I just had an exciting phone call from "P" and he also just texted me and said that he texted you with his news. We are so happy with his final grade for organic chemistry. I’ve been praying all semester that he would receive a passing grade.

A “B” in Organic Chemistry, in my eyes is an A++++++++++ !!!!!!!! The stress of waiting for his grade over the holidays has been lifted !!!!! Thank you so much for tutoring him and guiding him though this subject. I can’t tell you enough how much Paul and I appreciated it. "P" has done so well in all his classes but, organic was definitely a challenge for him.

Thanks again, Eddie. Wishing you a beautiful holiday season. Take care.

Thank you for checking in with me! Can I just say how much I admire you as a TF and how grateful I am for all of the energy and effort that you put into teaching us. Thank you, thank you. You have made learning organic chemistry a fun and doable process. I finished the Pset and I also completed all of the practice problems from this week's handout. I am reviewing the last two weeks of material by redoing the problems on the psets and on the weekly handouts. I'm planning on taking a practice exam today to gauge where I am with my understanding and focus on the areas that need more work.

If someone were to tell me six weeks ago that Summer Ochem at Harvard will be my best learning experience I would not have believed it given the amount of material to learn and the short amount of time to learn them in. But now this is my unequivocal best learning experience ever. Thank you for teaching me the ins and outs of Ochem and giving me this cherished human experience 🙂

I feel so fortunate to have found you as a mentor/guide/tutor for this challenging course. The fact you work so hard means I'm actually working with someone whose service is OChem centric and nothing else. I couldn't have asked for a better environment to learn OChem in, and most importantly, going through it with your support.

-California Institute of Technology student I did intensives with in September 2014 and during winter break 2015

This email was sent by my former MIT student to other MIT students about to start their first semester.

Relevant to people taking 5.12 this semester (I know there are a couple of you...and feel free to forward on to friends).

To give context, I'm now a senior and the whole 5.12 experience was initially real rough for me - it took me a good while to figure out what was even going on and how to approach everything, all while it seemed like many people in class had seen the material before. Ultimately I got through both 5.12 and 5.13 (even picked up the occasional A), but looking back, I wish I had wasted less time confused and consequently demoralized about it all.

When I took 5.13 last semester, I got in touch with Eddie, who's a top-notch orgo tutor. He is not MIT affiliated and does charge a fee, but in my case I found him and his resources very worthwhile. He knows orgo cold, is an extremely dedicated teacher, pleasant and professional. Everyone's background is different, but if you're anxious about first exposure, I definitely recommend checking him out.

Happy arrow pushing,
