There are a number of easy ways to contact me!
I prefer Google voice: 562-546-3326
If I don't have your number entered, I likely will not answer immediately, but if you leave a voicemail I will call you back.
Email in order of increasing formality:
matt (at) 3scan.com
mrg (at) mail.utexas.edu
mgoodman (at) email.arizona.edu
goodman.matthew.r (at) gmail.com
meawoppl (at) gmail.com

Various SNS (don't send me anything important here, I tend to neglect them!):
Or in person:
