Diana knows about cobbling together an income, tracking expenses, and pursuing a dream. She has spent over 20 years juggling the life of a performing artist while developing and maintaining her left brain as the managing director of an arts organization, a waitress, an acrobatics instructor, an office manager, a massage therapist, a bookkeeper and finally a full-fledged tax nerd and earning her EA. Through it all she maintains that connection is the point of everything.

Marci has provided a combination of tax preparation, bookkeeping and accounting services to a wide range of clientele, including individuals, partnerships, corporations and nonprofits for the past 20 years. As a longtime freelancer and award-winning novelist, Marci understands what it means to “hustle” for your dreams. In addition to tax work, Marci can be seen giving the occasional bike tour around NYC, or, most recently, feeding the feral cat colony that has taken up residence in their backyard.
