“I spoke with Chris at Oster & Wheeler and he was incredibly helpful and knowledgeable. If I end up establishing my business in New Hampshire, I will undoubtedly choose Chris to be my CPA. I certainly appreciated the time he took to help me decide whether it would be advantageous to establish in NH or MA. They had come highly recommended by a business associate and certainly lived up to expectation.”
