“They saved me over $100,000”

“Fleming Cronmiller is an amazing, highly personal, professional and knowledgeable organization which has saved me over $100,000 inside of 24 hours. They are not afraid to learn, and then know your business with absolute confidentiality. Don’t hesitate to give them a call, or feel free to contact me by way of reference.”

“If I could give more stars, I would.”

“My husband and I came to Margaret a hot mess! Our last CPA screwed us over big time, and left us at the mercy of the IRS with a whopper of an audit. Margaret talked us from our proverbial cliff, then painstakingly went through our entire paper trail for 2012 with a fine-toothed comb. She insisted that we not be at the audit (no argument there) while she went to bat for us. Margaret saved us thousands of dollars on our audit, and many hours of stress.

I’ve learned the hard way the importance of an honest CPA that really knows what they’re doing.”

“No hesitation in recommending”

“Have used Margaret Fleming for many, many years, and am grateful for her wisdom, professionalism and support. She has helped us with many issues that were quite involved. We drive up from the San Diego area annually, and give her a call as needed throughout the year. No hesitation in recommending her as a CPA.”
