Ive been working with Jeff and Mt. Diablo Tax Pros for going on 8 years. Jeff is easy to work with and has a true understanding of tax laws. He gets my taxes done quickly and effortlessly. I cant say enough good things. If you dont have a tax professional pick Jeff!

Mr.Rondini has been helping me with my taxes for over two years. He is extremely professional and dedicated! He even remembers most of my taxes related information, so whenever I have a question to him, he gets straight to the point.

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 doesnt leave me without answers. It helps with the stress that comes with taxes and filing.

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 had a phenomenal experience working with Jeff. He is a subject matter expert and was able to answer all of my questions. His customer service standards are excellent. He has a patient personality and is very flexible with his schedule. Not only did he take the time to answer all my questions, but he took the time to explain the different options i had, ran my numbers using both standard & itemized methods to help understand which route would bring me the bigger return. He is worth every penny and then some. If your looking for someone to get your taxes done that you can trust, feel comfortable that your in good hands, & pay an exceptionally reasonable price go see this man. you wont regret it. Thanks JEFF!!!

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

I have absolutely loved having Mr. Jeff Rondini as my taxman for many years! Im so happy I found him. Hes very careful to check & double check, reviewing each area & item relating to all aspects of not only the paperwork, but great care is also taken with the people he serves. He truly invests in those he is assisting, valuing each of us not only as clients, but as friends. I know this from how he has cared for me & my own tax needs, & have heard others express their satisfaction & appreciation over the years...I look forward to the time well spend together this year, & hopefully for many more tax seasons to come. Jeff is extremely professional, knowledgeable, trustworthy, thorough, sincere, & he is such a treasure... I always smile when I think of him :-)Peace & Joy to all who may read this ~ Cindy D.

Been using Jeff for years with filing my taxes. He always makes sure to take a comprehensive look at everything and get back the most money as possible while still remaining affordable. Will be following him to Mt. Diablo Tax Pros this tax season - definitely goes the extra mile in everything he does! I highly recommend!

New to Concord and went on to Yelp. Found Mt Diablo Tax Pros and read all the reviews. The one that convinced me to give Jeffery a shot was when one gentlemen asked for a quote at 1:30 in the AM and was upset they he did not hear back until 6:00 AM the next day.... He then proceeded to post of screen shot of their correspondence. Jeffery responded in short its very difficult to give you an accurate estimate since you have not told me any info about your situation, how many w2s are you single, IRAs, do you rent or own, etc.I felt anyone that would take would take the time to respond professionally and politely is probably a good bet. And sure enough he was. I would highly recommend their services. They are quick, smart, and willing to help you keep your money in your pocket. I will be taking my taxes to them next year.

My wife and I have been working with Jeff for several years on our tax return. He is both efficient and VERY knowledgeable so our return is always completed on time and to our best possible benefit. We highly recommend Jeff to anyone in need of tax assistance of any kind.

Weve been using Jeffrey to do our taxes, for quite a few years now. We couldnt be happier with results. We have special needs regarding our returns, and he makes it simple. Great communication , very timely, a real professional , and a hell of a nice guy. Looking forward to doing business with Jeffrey agian, soon.

This is my 2nd year with Jeff, and I am as impressed this year as I was last. He responds quickly, answers questions throughly, and assures you of the right choices to take when filing taxes. One painless appointment and your taxes are filed quickly and precisely. I appreciate his advise and support!

Jeff by far is the best tax preparer ive been to. He explained every paperwork filed and is very professional and knowledgeable.I would recommend him to any one looking to get their income tax paperwork filed correctly.

I have been seeing Jeff Rondini for many years. My whole family sees him as well. Jeff is very professional and it is clear to me that he always has my best interests in mind. He is knowledgeable and I trust him to do my taxes because I know it will be done correctly. I actually really enjoy having Jeff do my taxes because its like meeting up with a good friend and catching up on what has happened in the past year. Go see Jeff Rondini, you will be happy you did!

After reading Jeffs stellar reviews we decided to give him a shot and so glad we did! Great to work with, highly recommend.

I would use them as subcontracotrs.

Jeff is very professional in terms of taxa declaration, he explains very well the work he will do and provides useful suggestions in the process, he helped me with a statement from a past year and the process was simple, it is also friendly and fun.
