      Accounting Review from Dmitrii Legetskii

      This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

      Gabriela Condrea's Review Sourced from Google

      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!

      InlineAdam's Review Sourced from Google

      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.
