Individual Tax Preparation
Overall experience was good. Although, overpriced. I would highly advise to contact tax preparer to confirm their
fees for service prior to making an appointment.

Prepared my 2016 tax returns. It was obvious how knowledgeable Mr. Rondini was through out the process. He was very
easy to work with and extremely helpful in his explanation of the various entries/forms and attachments. It was a
pleasure working with him.

My wife and I have full confidence in Jeff's knowledge, ethics and abilities. We greatly appreciate his care
and concern in wisely managing our tax burden, and we find him to be a very personable gentleman who takes the
stress out of tax preparation.

Jeff prepared my 2014 taxes. He did a timely and thorough job, getting me the maximum return, without taking
risks that would put me in jeopardy if audited. His expertise was greatly appreciated.

I had a non-resident California state tax question and Mr. Rondini was very quick in his response, generously
offering the guidance I needed even though it directed me away from his services. I am impressed with his integrity
and professionalism!

Our returns were subject to an in-office IRS audit this year, and Jeff Rondini was our super-hero! I was
grateful for his calm demeanor and professional skill at puzzling through our situation. Not only did he make
the audit process easy to understand, he was with me every step of the way. He made great arguments to the
auditor on our behalf, and he sleuthed-out some errors that were actually in our favor. I will consider myself
lucky to be able to continue to work with Jeff on "growing up" our business practices. Thanks Jeff!

If you're fed up on giving your money to Uncle Sam, then Jeff is your go to tax guy. Jeff will try his very best
to maximize your returns. He is extremely knowledgeable and will give helpful advice on ways to
My husband and I have found our tax guy and couldn't be happier with his services.

I made an appointment to ask some questions about filing my taxes and about my deceased father's taxes.
Jeff was very knowledgeable, forthcoming and completely honest. He took time to talk with me at a time when he
didn't have any and did not pressure me to use his service. I highly recommend this office!

After many years of using another tax professional, we felt it was time to make a change. So three years ago,
we made the change and started using Jeff at Mt. Diablo Tax Pros. Since we own a business, he prepares our
Corporate Returns, as well as our Personal Returns. He is diligent in making sure he asks questions that might
uncover additional deductions. And, when questions have come up, after filing, he is there to help us
understand what needs to be done in order to resolve them. He also advises us on how we can best position
ourselves to take advantage of possible deductions in future years. Thanks Jeff!

I have worked with a few other accountants through the years. Jeff by far is the most responsive and is diligent in
understanding all of the details that go with filing. I needed help with self employment questions and he responded
quickly and with details. He really seems to care about providing correct and pertinent information, and is thorough. I
highly recommend working with him. I appreciate that he is available and doesn't leave me without answers. It helps with
the stress that comes with taxes and filing.
