SA$5.83/min per minute(10)Excel FormulasShir Aviv • New York, NYCreated 11 years ago in Technology / OtherMicrosoft Excel contains over 400 unique functions, along with comparison & arithmetic operators, custom VBA functions, and the ability to nest by up to 64 levels. The best part? You only need to know 10% of this to get 90% of the results (Pareto, step aside!). The possibilities are virtually endless, but I will teach you how to use the top 44 functions in ways that make even "Excel Experts" go "Holy Crap! I didn't know Excel could do THAT!!"Shir Aviv New York, NY(10)

Thank you for your input earlier today. It was very helpful. I am not ready to move forward with you on the spreadsheet today.
Thanks again!
Best regards,

Source: Clarity Cassie Liao Apr 26, 2015Shir is a master technician and teacher. He is simply an Excel wizard. He can navigate, formulate, and maneuver complex data with ease and precision. His command of the software and how to skillfully work within it is impressive and unassuming. His customer service is nonpareil, and he is a joy to work with, a charming sense of humor accompanying his instruction. I would highly recommend him to anyone who needs tutoring or assistance working with this indispensable tool. Shir, I thank you!
Source: Clarity Mark Hofmaier Mar 31, 2015Shir was amazing. I'm a writer with very few spreadsheet skills -- which is a real problem considering that I now work in content strategy. Shir showed me a few life changing tips + tricks to make my workday infinitely faster. Will definitely be hitting him up again!
Source: Clarity Jessica Adamiak Mar 23, 2015Thank goodness for Shir! It's evident by the way Shir answers any questions that he is truly passionate about passing on his knowledge of Excel to others and sharing his expertise. He works hard to make sure you understand the material and genuinely cares about your learning. He breaks down the concepts step by step and demonstrates to you using the real data he's collected on Excel. With Clarity, he is able to guide you through the problem solving process and help you build your own intuition.
