I Highly Recommend Michael O'Sullivan as Your Next Attorney!

I hired Michael O'Sullivan after receiving a letter in the mail from him when I was arrested for refusing a field sobriety test and breathalyzer after a small, at-fault, fender bender at a red light. As a result, I was charged with Refusal and DUI. His attorney fees are much cheaper than any other in... the area and he was very informative as to every step I needed to take in a timely manner to get my license back quickly with zero hassle. I never had to attend a single court date, and even though it was almost a year later, he got the refusal charge dropped and the DUI charge reduced to a reckless driving charge with a $440 fine. I am so glad he sent me his letter, or I may have ended up with a very expensive "corporate" attorney who probably wouldn't have even known my name. His communication was excellent, and he always answered my questions quickly. Thank You! I highly recommend Michael O'Sullivan! A+++

Best Attorney Ever {from bottom of my heart}

Absolutely amazing. I needed Mr. O'Sullivan's help a few years ago and he was truly "the best". Had a [very] recent traffic violation and once again, he was immediate in answering my call and handled everything in a professional and efficient manner. AND, may I add, speedy manner. I was quite stre...ssed out and Mr. O"Sullivan just "took the reins" and handled everything. The relief I felt was worth everything. This person not only takes care of whatever situation is at hand, but melts the stress of "said situation" away. Forever thankful. To anyone in a "situation": This is the person to hire. Truly.

All Charges Dropped / Very Professional

After being charged with a DUI, drug possession, and a speeding ticket, I was very distraught to say the least. Michael was a positive guiding light and very professional. He accepted my case, and was honest that the outcome may be less than desirable. After a couple of months, all charges were dismi...ssed. Michael always answered my communications and his honesty and capabilities as an attorney were astonishing. 10/10 would recommend.

Highly Recommended

I found Attorney O’Sullivan after being charged with a DUI. His reviews were positive so I had confidence in his ability to represent me. He throughly reviewed my case and was able to get my charge dropped. I highly recommend him.

Michael O'Sullivan

My experience with Michael O'Sullivan was fantastic. I was involved in an at fault accident with three charges being filed against me. Michael was very professional but also was interested in getting to know the real me. He kept me apprised of all aspects of my case and advised me of my options. ...I couldn't have asked for a better outcome considering the circumstances. I would wholeheartedly recommend Michael to anyone in need of a lawyer.
