For competitive sports, yes, I'm that dad... I yell, scream and am generally annoying. To help stop this and keep from embarrassing my children any more, I took up photography.
I did coach comp soccer (U10 silver), elementary school basketball and junior high school track and cross country, which have been very fulfilling. Currently, I'm a volunteer assistant for the high school running teams. I also have been back into running myself (inspired by my kids), so I'm trying to run more than a few times a week.
Feel free to check out my photo projects in the upper corner.
Currently, I work for Sony Interactive Entertainment (PlayStation) which is quite possibly the closest thing to a dream job.
