very knowledgable and met deadlines I needed. I liked his online portal system which is very easy to use to track documents. Very reasonable rates! He was very flexible and rescheduled an appt I recorded incorrectly- and made time to shuffle his schedule the same day. I would recommend him to others who need small or other business taxes and indiv. returns completed. Plus I prefer to support a small local business vs. any chains or franchise tax prep places!
