About Us

Mavrik North America

We are based in a 6,000 square foot facility in Santa Rosa which houses our management, engineering and field operations teams as well as support staff. It also houses our equipment fabrication center and warehouse.  Contact us today for a guided tour.


Our approach to everything is to develop either a new technology, or else a significant improvement to the way something is currently done.  Being "just another . . . " is not good enough.




Bob Kreisher, Ph.D.

Bob was born and raised in Indianapolis.  He graduated from Purdue University the year it started its Enology and Viticulture program, completely unaware of this development.  After many years in university administration, teaching, and consulting, Bob moved to California to help with the organizational design of an emerging winery.  Meanwhile, Bob developed a keen interest in developing technologies of winemaking that are gentle and cost-effective to allow cutting edge cellar techniques that enhance the expression of terroir and winemaking, rather than reducing wines to similarity.  After intensive research into available and emerging technologies, Bob formed MNA with Mariana Brown.  In his spare time, he enjoys cooking, film, hiking, gardening, travel, and spending time with his family and friends.
