Thanks to everyone who has reached out to us in the midst of the Sonoma/Napa wildfires.

Several of our staff were evacuated from their homes, which we hope have been spared, and access issues are keeping several others away, as well. The office itself, in the downtown area of the City of Sonoma, has been unaffected, and we’re working to complete the most urgent of client projects.

Phone calls are being routed to a cell phone in the office, as many phone lines in Sonoma are still down, so e-mail to mail [at] h-e [dot] com is probably the best method to reach us.

Thanks again!
Bill
