Roberta was the best boss that I ever had. She was brilliant, friendly, fun, and most importantly fair. She and her family have been friends of us and our family for many years. Because of her, we are better people and the world is a better place to live.

I have known Roberta for many years. I worked with her and then for her. I really felt it a privilege, as she was truly a wonderful boss. No matter if she just walked in from a weeks trip to China, or had stacks of work to do, she was always with a ready smile and took time for sincere concern for others. Roberta always treated me with respect. She treated me as an equal, even though I understood nothing at all about Alt Fuels and the like. Because of the caring person that Robert was, we became more than manager and admin, we became friends. I loved to hear her talk about her family. She loved them so, and spoke of them often with great pride. Always on her list of things she felt passionate about .. Alt Fuels; racing her cars and boats; rebuilding her Mercedes engine and playing her piano. Oh, how she loved all of life! She said that she learned the love of cars and mechanics from working in the garage with her dad. And whatever Roberta did, she did it with style and grace. She was quite a lady. I will truly miss our Dr. Bob. One last hug.
