I found them on the Internet and scheduled a meeting to review my tax returns from the prior years…read moreand talk to them about my current tax situation. I have always had my taxes done by a friend in Cleveland Oh, and just never took the time to find a new one. I scheduled through email and quickly got a response back. (I had emailed a couple places and this is the only one that actually returned my email) I scheduled a time and I think a week out to meet with them. When I arrived, I met with Nichole Thousand and we discussed my current situation and what she needed to take over my taxes and help me with other financial needs. I must say that I was very impressed and that she has made the transition very simple and easy and I feel full confidence in her services. Everyone I have met there has been extremely helpful and polite. If anyone still needs to get their taxes done, or needs advise for their business this is definitely a phone call you need make. Thanks Nicole!

My cousin suggested Mary Cay to me because I needed someone new to handle my taxes. The person I…read moreused last year didn't do a great job and I was ready to bring my giant pile of paperwork to someone and have them sort it all out. Mary Cay did that and more, and I couldn't be happier (or more relieved.) I went on the same day as my cousin and was totally taken by surprise at the "welcome board" she uses... it cracked me up! There was a big sign welcoming both my cousin & I by name, and you don't see that personal touch very often anymore. It at least let me know I was in the right place! I went upstairs and we laid everything I had on the table. Forms and forms and more forms. She took all of my information and then plugged a bunch of things in, which took about 30 minutes. What I LOVED about her services was that she explained what everything meant as she went along and I ended up learning so much just from the brief time I spent in her office. Her fee is reasonable, and what stood out to me was that it includes "anytime financial advice." I can call her or email her with questions about anything related to money throughout the year, and she'll be glad to help me. She also told me she thought it was great that I was taking charge of my finances and had everything organized, which made me feel ahh-mazing. The only thing better than having your taxes done early is doing business with someone you can tell genuinely cares about putting you in the best situation possible. I'll be using Mary Cay for many, many years! I'm crackers for Rackers.
