Explore their agency profiles, clients, reviews, cost and more to narrow down the best partner for your business needs.

      So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

      Alex Stackhouse's Review Sourced from Google

      Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

      Sharing our students' incredible stories is crucial to connecting with more people with mobility challenges who could benefit from our TangoStride Program. The team at RH Strategic took an interest in our mission and generously offered to spread the word pro bono. They pitched our story to just the right people, and landed us two local media stories with major news channels Q13 Fox and KING 5! Not only were they instrumental in our outreach to the Greater Seattle community, but they were extremely knowledgeable about the media process and their guidance was invaluable. Thank you, RH Strategic for helping us help people "Dance to Walk" with TangoStride!

      I've worked with many PR firms in Seattle and RH Strategic is at the top of my list. Their team is competent, creative, efficient and responsive. They are lead by John Raffetto who is unflappable, solution-oriented and always accessible. Highly recommended!

      The M16 Marketing team did a phenomenal job with our website! We were in a time crunch to get our new website up and running before an event and M16 delivered (before our scheduled launch date). I would definitely recommend this team of professionals. They are top notch.

      The team at M16 knocked it out of the park for us. Having worked with a few other firms, we saw an immediate difference in terms of organization, responsiveness and communication. Don and the team were incredibly helpful and delivered on time, under budget and surpassed our expectations. Absolutely recommend...in fact, I've recommended them twice already.

      RA's Review Sourced from Google

      As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.
