About Thielen & Associates, Inc.

Thielen & Associates, Inc. was launched in 2004, based on a collaborative idea from our Managing Director, Paula Thielen, and her adult children Jeremy Thielen, and Marisa Thielen Fugate. Their entrepreneurial vision was to create a full service accounting and financial services firm that would not only allow them to share their accounting experience and knowledge with individuals of the public, but also assist fellow entrepreneurs in their visions and establishment of their own successful businesses.

They believed that they could establish a firm that valued relationships, and they felt that by viewing every client relationship like a partnership; their success would be a direct result of the client’s success. They committed to providing close, personal attention to each client, and took pride in giving the clients the assurance that the personal assistance they received came from years of advanced training, technical experience, and financial acumen. Their continual dedication of time and resources in professional continuing education, state-of-the-art technology, and extensive business relationships is indicative of their commitment to excellence.
