About Us

Tim Jochner was born and raised in Walnut Creek, and has resided in Walnut Creek ever since.  Tim has owned and operated 4 successful businesses in the financial services industry two of which were separately honored by Entrepreneurial magazine as top 100 fastest growing companies.

Tim currently owns and operates Shadowbrook Winery  as the only bonded winery in Walnut Creek, and serves as Chairman and Chief Executive Officer of Diablo Vineyards.

Mark Jochner serves as President and Chief Operations Officer of Diablo Vineyards.

Mark has been in business for himself for over 20 years in the Landscape contracting business all over the bay area. Mark is professionally licensed for a variety of pest and disease eradication and is well versed in all horticulture and viticulture health and compatibility.

In Mark’s experience most home vineyards thrive. This, he concludes, is because home vineyards tend to be better cared for than larger, commercial vineyards . . . "We are targeting central Contra Costa and down through the tri-valley," says Jochner.

"The soils and sunshine are conducive to vines.  We've learned a lot over the years about planting, constructing proper trellis systems, drip irrigation - and premium wine grapes . We have also found that vines are very forgiving . . . We've done wine making and wine growing classes at UC Davis and continue to learn from several professionals.

" If you think you know everything there is to know about vineyards your in trouble, so we continue to learn everyday "    ~   Tim Jochner
