"Add-Venture has been a key business for us as we have grown our revenues. Cheryl came in at a time when our books were a bit of a mess and helped us develop systems that work for us "creatives." She is always quick to answer questions and a pleasure to work with, and her website lets us communicate with her from all over the world (which we often do). I would recommend Cheryl without reservation."

"Cheryl has been a lifesaver for us. Her knowledge and expertise took away all the headaches and worry of trying to figure out complicated returns on our own. She was aware of adjustments and procedures we easily would have missed. She also directed us towards an excellent financial planner, and their collaboration about our financial needs and planning is a tremendous value. There is no way I would go back to trying to do returns on my own; Cheryl has saved us invaluable time and money."

"I have worked with Cheryl for the past eight years. She is incredible, and I have been 100% satisfied with her service. Her work ethic is impeccable, and she is efficient, accurate and honest. She knows her stuff, and I have the utmost confidence in her ability. She has handled a variety of complex tax issues for me with ease, and always puts me in the best possible position to maximize my returns. Let's put it this way, if Cheryl ever decides to leave Portland, I will follow her - at least my taxes will!"
