The communication & experience you hope for with an attorney
I contacted Seth to discuss a parental timesharing issue and a support order issue. The cases in question, where very odd and needed an extensive amount of work. Seth was EXTREMELY prompt with communication. He explained what he was allowed to straight forward, in a very relatable and real way. He didn't communicate in legal jargon I wouldn't understand. It was the type of communication and experience you hope to have when speaking with an attorney.

Amazing attorney
I was pulled over for going 72 in a 50. I would've had my license suspended but because of his experience and knowledge of the law, he was able to get me a withhold and driving school. He is extremely talented attorney

Direct, Professional, Efficient - 5 Stars
I called Seth on Monday about a traffic court appearance I had to make that Thursday. He worked quick and diligently, told me what I needed to do and then met me a traffic court and got everything handled without incident. He was straightforward, informed me of what could happen and what steps we would take if it did. If I ever need an attorney again, he's the first person I'll call.

From consultation to verdict, Seth delivers.
Seth Mazirow represented us in a traffic matter and we were totally satisfied with the outcome. Seth's consultation is top notch and I cannot stress the importance of being informed of all options from an experienced, courteous professional. Thank you, Seth. Glad we choose you.

Highly Recommended!!!
Seth was extremely proficient and very personable. My husband and I have gone to him for two totally different issues and with both he was extremely helpful. He was always available and quick to respond, even when he was dealing with his own sickness. He saw the urgency in one specific matter and was on top of it, I had no concern with anything falling through the cracks. He is honest and it is evident that he cares about what he does and was sure to make you feel like you are a priority. We were very impressed with this lawyer, we will always go to him if we need representation in the future. Highly recommended!!!!

Attorney Seth Mazirow is your go to man for allnyour Legal Needs! Honest as the day is long!
Seth is the most thorough and honest attorney we've ever dealt with. Myself and my child and ex were involved in a domestic, he not only helped with injunction immensely, but was in constant communication with me and her biological father too. Seth works with his clients as a team and tirelessly communicates with all parties involved for a quick and fair resolution to all matters. All correspondence is copied to ALL parties involved. Seth Mazirow also follows up several times weekly via email or cell (yes you get his personal cell), to remind you of upcoming hearings and/or new developments. He accommodated our schedules to meet in office when face time need or documents to be signed. Finally, Seth went above and beyond to help in establishing paternity and name/birth certificate/and SS card by researching aspects. His rapport with the court system and honesty and integrity makes for a very good relationship with Judges and court personell. No bluster, easygoing. Worth every dime. I'd recommend him to all I know! Bonus: Our toddlers attended same Daycare center, and although his son was sick, he stopped by pool party with a lovely gift from his beautiful family. As a Lawyer and a family man, you can't get better representation.

Excellent lawyer who saved me time and money
Recently I received a ticket and decided against just rolling over and letting the indifferent State take my money and add points, so I took advantage of my company's legal plan and chose William Seth Mazirow (henceforth named Seth) from a list of many lawyers representing minor traffic violations. Always courteous and of good cheer, Seth answered all of my questions over the phone and in emails, suggesting a plan of action that would lead either to my case being dismissed outright or using my good driving record to ask the court for mercy (my words, not legal terms). Seth took care of all paperwork and went to court as my representative, so I did not have to. At the hearing he spoke with the police officer who had shown up to take the report (but had not witnessed the minor accident) and got the officer to assist him in getting the case dismissed! Couldn't have received a better outcome. Thank you, Seth Mazirow!

Traffic Case
I’ve received a traffic ticket the FHP in Tampa. I was so upset on the reason why the officer pulled me over, I decided to fight the ticket. I was looking online for a good attorney that handles traffic court cases. I went to Mr. Mazirow website and notice that he is highly credential, very knowledgeable, and very down to earth. Because of his expertise, he was able to give me the best possible solution to my ticket situation. If you have any issues with any aspect of the law, he is the attorney to go to.

Seth Mazirow
My name is Anthony and I'm a current client with Mr. Mazirow. If you need a lawyer this is your guy. He has been my attorney for several months almost a year now and has worked with me through several occasions mainly traffic but a criminal case also. Seth has got me an unbelievable 4 withholds with my traffic cases and has saved my license from being suspended when I thought it was definitely going to be gone. He is very familiar with the judges and prosecutors office and they know him as well. He is always on time and is extremely knowledgeable and has done his best and an amazing job from keeping me out of jail/prison. I would recommend him to anyone he's a phenomenal lawyer.

Not one bad thing to say even when looking for one. My highest recommendation for divorce proceedings!!
I was contemplating divorce for a year and during that year, I went to a few different lawyers before taking the plunge. Everytime I went in for that first consultation, the feeling was the same. It was cold, unpersonable, judgemental, terrifying, nerve-wrecking, and completely unhelpful. So much to the point that I bailed on the idea of divorce all together for the time being. The last time I went on the hunt for a divorce lawyer, I came across Seth Mazirow and from the very first phone call, I knew it was the right time and the right place with the right lawyer!! He was friendly and welcoming. He explained everything to a tee. He never once acted like he was above anyone or judgemental of my situation. I am young and relatively inexperienced on legal matters but he took the time to give me every bad or good outcome possibility and all the steps leading up to those scenarios. During the court proceeding, he was so assuring and went over our case thoroughly. He never acted bothered when I had questions or called out of a scheduled time. He was absolutely awesome from start to finish. He has raised the bar for the expectations that I have for future legal needs. I believe that he said he does family and criminal law (but dont quote me on that one.) In any event, hes as good as the best legal respresentation out there but what sets him apart from the rest is that he treats you and your situation with compassion, like a human being. He comes with my highest recommendation!!!
