HENRY, WATERS & ASSOCIATES INC. REVIEWS

My relationship with this business dates back to the 1990's. My husband and I both have relied on the professional expertise and counsel for our individual business' needs, as well as our personal tax filings. Steve Henry is top notch in the field and has put together his team of well-qualified folk with the integrity and interpersonal skills that we have come to rely on. We have the peace of mind that we are in great hands. I highly recommend Henry Waters & Associates for business and/or personal accounting and tax services.

Couldn't be happier - the entire team is professional, knowledgeable, easy to communicate with, and supportive - and Steve is simply wonderful. Highly recommended.

He handles our payroll and taxes for our small/medium businesses and does a great job.

DELTA EFFECTS, LLC REVIEWS

We switched tax providers this year and reached out to Anu, and we couldn’t be happier with the experience. She was incredibly responsive from the start, met with us promptly, and took us in as new clients without hesitation. Our tax situation is complex, but she handled everything efficiently and delivered a quick turnaround. We truly appreciate her expertise and professionalism and look forward to working with her in the future. Highly recommend.

My family has been using Delta Effects Taxation Services for the past few years, and we are extremely happy with the support provided by Anu Singh and her team. Their professionalism, accuracy, and timely assistance have been outstanding. We strongly recommend Delta Effects for anyone looking for taxation, bookkeeping, and related services.

Anu has been doing my business and personal taxes for years. She and the people at Delta Effects are efficient, expert and friendly. I highly recommend them for your tax perp and small business accounting. They are terrific.
