Worst accounting firm in California - don't believe the other reviews as they are not legitimate. These people will swindle you out of your hard earned money and charge you more than what you owe the IRS. It will feel like an audit when you do your taxes here, just because they think they are elite claiming CPA, doesn't mean that they are entitled to steal from you which they most definitely will

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

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.
