By the way we are getting married in Sebatopol, so we have been looking in sonoma county and also San Francisco area.
My husband and I got married this past July in Santa Rosa and used Perfect Day Music (link to their website below) as our DJ service. Noel Plumb - the owner- worked with us to create a playlist for all aspects of our wedding that suited both of our personalities. Perfect Day Music is very affordable, dependable and energetic and they are based out of Santa Rosa, CA. Both my husband and I recommend his company for your wedding. Although, Noel didn’t personally DJ our wedding, we had one of his top DJ’s (Steve) and he kept everyone on the dance floor all night! I would definitely check it out...his company provides a free consultation, so you'll be able to see if you like what he has to offer first. I urge you to reserve your date early, though, because he books up quick!
