Alan’s expertise and thoroughness really helped us launch the acupuncture we’ve been envisioning. He has an everlasting patience and desire to educate us about how our business can best grow. His tax knowledge has helped us make better and better financial decisions as a budding company. He even offers us help on doing our own personal taxes, and how those choices interweave into our business tax decisions. Highly recommend.
