I'm David Lee. I have a B.A. in Psychology but actually started out a math major for my first 1.5 years of college. I have worked in Healthcare Finance and Analytics since 2006. I am a husband and father of 2 girls. I get a lot of enjoyment helping them with their math homework. They also tend to come to me for math help - I believe it's due to my patience and ability to re-word the material in a way that makes sense to them. I use Excel for my job daily. I mostly use Excel to take large datasets and turn them into meaningful summaries so Senior Leaders are able to make decisions about how to run their departments. I've always loved Math. Most of my life, I thought (and was told by people close to me) I would be a math teacher. It's interesting because even though I didn't become a teacher, the most fulfilled I've felt at my job is when I get the opportunity to assist my team/co-workers with their Excel needs by helping them with a formula or thinking through how to summarize a dataset in a meaningful way. Whether it's helping my co-workers with Excel or students with their math homework, I'm always focused on providing just enough information for the student to have ah-ha moments for themselves without doing it for them. If they can't do the work without me there, I've done them a disservice.

I use math every day in my job through Excel formulas. I have led and co-led several internal Excel trainings at my current and previous job. Co-workers often ask me for help with their Excel needs because they know they'll get a quick answer or, if they are interested in being able to do what they're asking on their own, a quick lesson so they'll be able use the skill they just learned at a later time.

I tutored a classmate in high school Algebra. I also tutored a local middle school math class as part of my Psychology studies in college. Now that I have children who are going through Common Core math, I have been impressed with how Common Core structures the lessons. I see math as different rungs of a ladder with ma
