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.
Mail and checks payable to:
