I have known and used ECS Financial for many years - both for my small business accounting needs and for our personal tax returns. Here's what great about ECS: - Professionalism without jargon - Listening - they really listen to understand what your challenges are and what you need - Solutions - Tobey W, Sam O and all the other staff I have worked with talk me through options/pros and cons - No up-selling. Based on their dedication to listening, they offer you all the services that you may need, but never any pressure to do more business with them than you need - No-surprises billing. I pay what I consider to be appropriate fees for the highest quality accounting services and advice I have ever had!

We are so happy with the services of ECS for our personal tax preparation. We have had questions during the year and received an extremely timely response each time. We will return this year. We worked with Tobey W. and couldn't be happier with his clear explanations and guidance. This is a stable company, with good staff, and a reasonable price.
