David Schomer

Career Schomer became known within the coffee industry for his innovations, such as how he customizes his grinders and espresso machines with PID controllers to achieve a more constant water temperature.

Besides training hundreds of baristas who went on to influence coffee shops across the country, Schomer self published a book on espresso techniques in 1994, while also writing columns for Café Ole magazine in the 1990s. Schomer's 1996 Espresso Coffee: Professional Techniques has been described as "the industry bible".

Schomer credits Espresso Vivace's survival in a competitive market to his own "absolute fidelity" to the goal of "making a better cup", together with the sound fiscal and operations management of his business partner and former spouse, Geneva Sullivan.
