“I have been in business for almost 12 years and have worked with several CPA companies but EWH really tops them all. While searching for a CPA, I was looking for someone who would act as a community partner, someone to learn and understand how I work as a business owner as well as how we handle our finances. Liesel and Jon with EWH have become my trusted advisors, people that I can call and ask for financial (as well as other business related) questions and I always value their guidance and feedback. They really go above and beyond to help me out and it helps me so much to know that I have them on my side. They laugh with me, but yet they understand and validate my bad days. I’m so thankful for their partnership!”
