I found myself in a very unfortunate, and unfamiliar legal situation. I had two previous attorney's on retainer who both advised me to take a plea/settlement deal, which I did not want to do as I knew once the facts of the case were laid out the verdict would be not guilty. Unfortunately, no attorney wanted to take on the size of this case, and all continued to pressure me into taking a plea deal, until I met Greg Whittner, from Rosenblum, Schwartz, Fry. and Johnson. Mr. Whittner, went ABOVE AND BEYOND in finding evidence, witnesses, completing depositions, among countless other things to get a clearer picture of the actual facts. Once Mr. Whittner, gathered everything he informed me that under no circumstances should we consider a plea/settlement deal. He was able to completely dismiss the first case/charges before entering a court room. The second case/charges, we took to court and after fierce litigation, and facts we were able to find a not guilty verdict. Not only did Mr. Whittner do his job exceptionally well, he was able to save my reputation and character and prove that the charges were meaningless and fabricated. If I ever find myself in an unfortunate situation, Greg Whittner will be my first phone call.

We heard Rosenblum Schwartz & Fry were the best of the best and it’s so true! Greg Wittner represented our son and we are eternally grateful for his help. He was able to keep our son out of jail and get him the treatment he desperately needed. Greg was always available and communicated with us every step of the way. We would highly recommend him and this law firm.

We hired Rosenblum Schwartz & Fry, P.C. for our son and it was the best decision. Scott Rosenblum and Greg Wittner were able to keep our son from jail time and get him the help he needed. Greg Wittner represented our son and he made himself available at all times. He went above and beyond to communicate and explain everything to us. He is the best and we would highly recommend him. You are truly wasting your money and time if you choose to go anywhere else!

If you want a lawyer who will treat you like family yet professionally Greg Wittner is your attorney. He took a family member’s case with confidence. Leaving his office the first time I met him I could breathe a little easier. I had Greg’s cell number from the first meeting. I spoke with Greg at 8:00 pm, on Sunday’s he never ignored us. I left the courtroom yesterday knowing my family member would not be spending years in prison. This is thanks to Greg Wittner. He is amazing in the courtroom. I put all my trust in Greg and he did not disappoint. I can’t say enough about this gentleman if you are in need of a great attorney and a person Greg Wittner is the person you call. Thank you Mr. Wittner .

Greg Wittner did a fantastic job of handling my case. He was very communicative and thorough, and his professionalism is second to none. Greg is an exceptional attorney, and I trusted his advice and also appreciated his genuine and patient demeanor. I would absolutely recommend him to anyone. Thank you again Greg!

Greg Wittner was amazing. I went through 2 other lawyers that I had to fire because they kept trying to persuade me to accept the charges brought against me instead of working on my behalf. Greg is straight-forward and to the point. He did not try to persuade me to accept something that would change my livelihood, instead he did what any GREAT lawyer would do and used his expertise and knowledge of the law to help get my case dropped! I am now able to work in finance again and do not have this hanging over my head so I can move on with my life. Without Greg, that would not have been possible! I recommend Greg because he is not fake and won't give you the run around with BS like most lawyers do just to get your money. From personal experience, I can confidently say he is very skilled & ethical, forthcoming, is not afraid to put up a fight for you and is worth every dime you pay!

Greg Wittner,

Thank you for all the work, and time you dedicate to your clients. Your professionalism is second to none. Your ability to make your clients feel serene at the most challenging time in their life is priceless. Your equanimity in the court room is appreciated, and respected.

Greg Wittner was my attorney and he was beyond amazing! My case has been a mess since day one and has involved multiple states and through everything he was awesome! Even though my case involved 3 different states and I currently live in Florida he always made it easy to contact and communicate with through the whole process. He kept me in the loop every step of the way!! I should have been sentenced to 7 years but thankfully for his hard work I only got 5 years probation. Words can not express how truly grateful I am for him. He bent over backwards for me and I am blessed!
