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!

Web Development Review from Liz Ryan
Handbook handles our website development and web-based front end product development. From the initial concept to the final launch, the team always demonstrates a deep understanding of our needs, and delivers on the requirements quickly and completely.If you're looking for a skilled, reliable, and innovative website developer, I highly recommend Handbook. They have been a fantastic partner, and we look forward to working with them again in the future!

Web Development Review from Victoria Lee
I can count on one hand the number of companies Ive worked with in my career that possess the same level of dedication, responsiveness, attention to detail, and trustworthiness as that of an internal team and thats because theres only one: Handbook.First and foremost, Id like to say that if you're considering working with Handbook for your design and/or website development needs, you absolutely will not regret it. The Handbook team goes beyond simply executing our requests, which has not only been refreshing but has also been key to our growth as an online SaaS business.Handbook genuinely cares about our user experience, website performance, and broader business goals. Instead of just implementing what we ask for, they actively evaluate our needs and offer thoughtful recommendations to improve our outcomes.In addition to the quality of work and forward-thinking perspective, we know that we can count on Handbook to be there when we need them. From countless late-night sale asset takedowns to weekend staging QAs so we can feel confident about Monday morning launches, I have never experienced this level of communication and dedication from a company.I would recommend Handbook time and time again to absolutely anyone in need of web development, design, or messaging support. These guys are a rare find and your only regret will be that you didn't start working with them sooner.

Salesforce Review from Rishi Kumar
I had the opportunity to work with Accenture on implementing Salesforce with ServiceMax. Their expertise and dedication were impressive. Accenture's work on implementing Salesforce and the ServiceMax managed package was invaluable, significantly benefiting our organization's operations and efficiency. However, one area for improvement would be the documentation process. It was challenging to access comprehensive documentation, which slowed down certain aspects of our project. Nonetheless, I recommend Accenture as their talented team delivers exceptional results.

Alita vanZyl's Review Sourced from Google
Attending the LCG Open Coaching session, Looking Back to Lead Forward, facilitated by Tony Martignetti and Geraldine "Jerry" Anathan on 6 December 2024, was a transformational experience. This special year-end session masterfully guided us through a reflective and engaging journey, revisiting the milestones, lessons, and challenges of 2024. The atmosphere was interactive, insightful, and filled with moments of fun and discovery. Both Tony and Jerry brought an exceptional energy and depth to the session, making it both enjoyable and meaningful. These sessions are highly recommended for anyone seeking to gain clarity and direction while celebrating personal and collective growth.

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!
