Let’s Work Together

If I’m not off the grid and out of service, I try to respond to most inquiries within one business day. Here are your options for reaching me:

  • Call or voicemail my office line at 406-530-8901.

  • Text my cell at (406) 208-4228. You can call this number too, but I’m usually working during the business day.

  • Email me at zhassler@mammothsurvey.com. What do you need? By when do you need it?

  • For infrastructure projects, Google Earth is my preferred way to communicate survey extents and needs.
