Got calls from this number a few times. No message. It appears to be a company called the Henne Group. Supposedly involved in "sustainable real estate solutions". In other words, they are soliciting business (probably from real estate agents).

Got a couple calls from this- University of San Franciso. Wanting me to participate in a survey regarding Lupus. It is completely legitimate and based upon info provided via web form, but it's possible someone entered your number by mistake instead of their own. The guy who leaves a voicemail, Tom, is pretty good and will fix it for you if needed.
