"I'm sure you will be pleased should you need Mark Sizemore's help!"


Mark has been our family accountant for almost ten years. We were previously using a very large and reputable accounting firm that was quite expensive. We gave Mark a try many years ago in order to help a start up small business, and have never regretted it. Mark saves us money, in that his fees are less than our previous accountant, with the added bonus of providing us with a very personal touch. I can call or text Mark at any time during the year to ask him to clarify something I don't understand related to our tax situation, or whether I should save a certain receipt, or any other real estate or financial-sense related question I have. He's wonderful! I'm sure that I've asked him the same questions numerous times, but he never fails to return my call or email within 24 hours and graciously educate me, yet again. I'm sure you will be pleased should you need Mark Sizemore's help!
