Meryl Rubenstein

As a child, Meryl sometimes hoped for sick days when her mother would bring out a rainy day projects book and they would create things together. Since then, she has continued her love of crafts in her collages and greeting cards using paper, paint, fabric and sometimes even polymer clay.

She has been consulting as a Certified QuickBooks® ProAdvisor for many years, smoothing away the pain of record keeping and financial reporting for small businesses and individuals. And she loves to crunch the numbers for Tam Makers.

Niles Wertz

Niles, Tam High Class of 2019, has a passion for wood turning. He has been wood turning on the lathe for over 8 years. He began wood turning here at the Tam High Wood shop when he was just 9 years old. Niles makes wooden bowls, both sculptural and functional from local trees which he sells at local arts and crafts shows.

Niles has taught Introduction to Wood Turning at Tam Makers, but alas he is going off to college this year. We will miss his teaching skills.
