@oodleMD - The best money I have ever spent has been on an accountant!
I think we all have our strengths and weaknesses, so I highly recommend outsourcing as many of your 'weaknesses' or the things (especially as a physician) that take you away from patients!
We are also in Washington State, and would highly recommend Helium Tax out of Bellevue, WA. You'll likely talk with Howard or Ryan, and tell them that Jason with Assurance Healthcare pointed you to them. They're a great team that are big fans of DPC.
They will also be able to scale with your business as well, and can help with retirement plans, wealth management, and much more.
