My name is Tom Steenhuysen.
This last name is difficult to pronounce in English. I also have to spell it each time someone calls me. "Last name is S-T-E-E-N-H-U-Y-S-E-N ... first name is Tom. So many times I end up saying "just call me Tom."
I started using 'Just call me Tom' as a tagline to easily be remembered and then purchased the domain name justcallmetom.com
