About Charles
Biography
Former expert witness in Breath Testing and Field Sobriety Tests turned crminal defense lawyer, Jeff Sifers bases his law practice in Oklahoma City while serving all of Oklahoma. Mr. Sifers practice has a distinct focus in the defense of those persons accused of Driving Under the Influence, but also extends to serve those people who have been accused by the government of committing other crimes. The Sifers Defense Firm has a singular guiding principle at its root: That all people who have been accused of a crime are innocent until PROVEN guilty. Mr. Sifers' firm works to perserve the client's rights by holding the government to their burden of proof, and making sure that a plea of guilt is the very last option - not the first or only.

Charles Jeffrey Sifers's Lawyer Endorsements
"I endorse Charles. He is a highly skilled attorney that is well respected in the legal community."
"Mr. Sifers is an exceptional attorney. Although I have been practicing law for 24 years as a judge, magistrate, law professor, prosecutor, and private attorney, I learn from his responses on Avvo every time that he posts. If I needed an attorney, I would hire him. I recommend him with no reservation. It would be the best investment of your life to hire him to represent you."
"I endorse this lawyer."
"Jeff Sifers is an absolute "expert" in the field of DUI defense. I first met Jeff some years ago when he was a guest lecturer on forensic breath testing. This is a man that can actually take apart a breath testing instrument, and put it back together again. His knowledge of the science in DUI cases is unsurpassed. I have sent cases to him in the past, and will do so again in the future. I hold Jeff in high regard."
"I have known of Jeff for more years than I have known him personally and more than he has even been a lawyer. He was able to influence the field of DUI defense before even graduating from law school by being an expert in areas of DUI defense like Field Sobriety Testing and Intoxilyzer 5000 issues. I have witnessed Jeff lecture and even lectured alongside him and I endorse him without hesitation. I am proud to have Jeff as a colleague and look forward to fighting the good fight with him for years to come."
"Jeff is the best choice for you if you are charged with a DWI. He has attended some of the most complicated scientific continuing education classes in his effort to be the best attorney possible. He is thoroughly dedicated to his client's best interest and is the best choice for you if you have had your blood drawn and charged with DWI. He understands the government's tests better than the government's lab analysts themselves!"
"I endorse this lawyer. Very professional and knowledgeable!"
"Smart lawyer."
"Jeff Sifers is one of the hardest working DUI attorneys I know. He is an unstoppable force when it comes to presenting a defense for his clients, and his willingness to roll up his sleeves work until he finds a solution is what sets him apart from the pack. Jeff is one of the elite DUI attorneys in OK and will serve his clients in a manner that will leave them with absolutely no questions as to why they hired him for their defense."
"I have known Jeff for a number of years and have always been impressed by his knowledge of the law and the science relevant to DWI/DUI testing. The first time I met Jeff he took me aside and shared a great deal of information about the Intoxilyzer 5000, the evidentiary breath tester then in use in my state. It quickly became clear that he knew that machine better than almost anyone. Without that kind of knowledge a lawyer has no hope of defeating the breath test result. I give Jeff my highest endorsement; if a member of my family received a DWI/DUI where Jeff practices he would be the first person I called."
"Jeff Sifers is one of Oklahoma's premier DUI Defense attorneys. Jeff recently offered his gracious assistance to me in resolving a situation with an Oklahoma-licensed driver who had faced a DUI charge in Mississippi. I am confident that his knowledge and experience of DUI law in Oklahoma is second-to-none. I fully endorse and recommend him for anyone in need of legal help in Oklahoma."
"I endorse Jeff's work. Jeff is a highly respected DUI defense attorney who is well liked by his clients. You will not go wrong if you hire Jeff Sifers!"
"This is an easy endorsement to write. Attorney Sifers clearly has the reputation, knowledge and experience to not only handle any case that is put before him, but to do so in a professionally aggressive manner so as to insure that the consequences are either minimized or eliminated. As evidenced by this lawyer's personal endorsement (as I am physically located in Pennsylvania), Attorney Sifers enjoys a truly well-earned national reputation in this area of law. In addition, he is a man you can trust."
