I had the pleasure of meeting David Oase for a consultation. He is extremely knowledgeable, polite, and professional. I was blown away by the level of customer service he provided. I'm so elated and thankful that my husband and I can be his clients!! I had also spoken to a member of his team, Vanessa, when I intially scheduled my appointment. She was very informative, patient, and friendly. (My husband and I are also going to use his firm for our tax returns!!)

Before working with David and his team, my previous bookeeper kept me in the dark. I never had timely financials, and business planning for my Tucson based small business was impossible. Firing her and hiring David and his team was a game changer. David, Chad, and Vanessa make sure I have timely, accurate financials every month, and I can also regularly run my own reports. Working with this team is like having a fractional CFO. They also help me with staff financial KPIs. That level of service (and the fact that they are also very fun people) made me choose them over other accounting firms we interviewed nationwide. If you want accurate books and timely, insightful financial guidance, this is your team!
