Tax Preparation Review from Parhum Moshki
Dimov Tax was exceptionally helpful and fair-priced when assisting my family with complex tax questions that involved cross-border considerations. They made sure all of our filings strictly adhered to IRS regulations while maintaining the highest standard of quality. It gave us complete peace of mind knowing everything was handled professionally and completely by the book!

Tax Preparation Review from Gerald Triplett
Working with the team at Dimov Tax has been a fantastic experience. I have relied on them for my filings over the last four tax years, and I always feel confident knowing they genuinely look out for my best interests. They are dedicated, reliable, and consistently advocate for their clients!

Tax Preparation Review from Рубен Газарян
This is easily the finest tax firm I have ever worked with. As a long-term client who grew up outside the United States, I find the American tax system incredibly complex and confusing. However, Kirill Solntsev and George Dimov made my highly complicated 2025 tax return feel completely manageable. Kirill’s exceptional professional support, patience, and meticulous attention to detail were incredible throughout the entire process. They offer top-tier individual tax planning and filing services at a great price point. I wish them continued success and look forward to remaining a loyal client for many years to come!

RH Strategic was our PR firm for several years and was critical to our strategy. I couldn't be more grateful for their assistance to help build over a $100M revenue consumer business. Thank you!

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!
