Mary Mar Keenan - Designer/Owner

MMclay is a handmade tableware business run by local ceramic artist and designer, Mary Mar Keenan, in her Hayes Valley studio in San Francisco. Mary Mar's pottery is used throughout many popular restaurants, and as a result, has become highly desirable tableware throughout private home collections as well.

In 2014, she designed and produced a collection of work for Stuart Brioza's (James Beard Award Winner Best Chef: West) most recent venture, The Progress. From this collaboration The Progress Collection was developed and has been featured in Food and Wine Magazine, Remodelista, Saveur, San Francisco Magazine and many others.

Mary Mar has also produced tableware for an array of other top-tier restaurants in the Bay Area and other cities in the U.S., including Nightbird (SF), Single Thread Farms (Healdsburg), A16 (SF and Rockridge), Octavia (SF), BearCat (New Orleans), Wildhawk (SF), BirdDog (Palo Alto), Alloy (Miami), Goose & Gander (St. Helena), Bellota (SF), Pendulum (Vail), and a variety of smaller projects/collections.
