Charles Lyndel Sifers

Mr. Sifers was Oklahoma's FIRST Member of the National College for DUI Defense. Mr. Sifers was Oklahoma's FIRST Sustaining Member of the National College for DUI Defense. Through his efforts, MANY other lawyers followed and became members of this national organization which is the LEADER in making lawyers better in defending persons changed with alcohol related traffic charges.

Mr. Sifers is the ONLY Oklahoma Lawyer to ever be elected to the Board of Regents for the National College for DUI Defense. He was elected to the Board of Regents of the National College for DUI Defense on July 26, 2000, and served until May, 2005. Less than 40 men and women in the world have EVER reached this level of recognition in the field of DUI Defense.

In 1996, Mr. Sifers was the very FIRST attorney in Oklahoma to own an Intoxilyzer 5000. At that time, there was probably less than 10 lawyers in possession of these law enforcement machines in the entire nation. He has been an intense student of these machines since 1996. He now is a co-owner of eight of these machines!

In 1996, Mr. Sifers became the FIRST DEFENSE ATTORNEY in Oklahoma to receive CERTIFICATION & FORMAL TRAINING as an Operator on these Intoxilyzer 5000 breath test machines. These machines are the primary testing device in DUI Cases. Until 2000, he was the ONLY such qualified defense attorney. In that year, the Oklahoma Board of Tests for Alcohol and Drug Influence (the Oklahoma State agency over these machines) held it's first class for Certification of NON-LAW ENFORCEMENT Operators and Supervisors. Mr. Sifers - and C. Jeffrey Sifers, his son and law partner - made up ½ of that training class! He has maintained his certifications as a breath test Operator and Maintenance Specialist every year since.  In 2006, Mr. Sifers became the FIRST defense attorney in Oklahoma to graduate from a formal training course on the NEW breath device, the Intoxilyzer 8000.

Mr. Sifers is the ONLY lawyer in Oklahoma who holds a certificate of successful completion (May, 2003) for the Robert F. Borkenstein Course on "Alcohol, Drugs, and Highway Safety: Testing, Research, and Litigation" based out of Indiana University at Bloomington. This course is for STATE WITNESSES to testify against DUI offenders. It is taught by the top forensic scientists in the world (Dubowski, Jones, Forney, etc). Only a handful of defense attorneys have been allowed to complete this course.  And, since Borkenstein has now been closed to private attorneys, no other lawyer in Oklahoma will EVER complete it. As a result, Mr. Sifers has been exposed to the "other side's" schemes unlike any other Oklahoma lawyer. This is a benefit to his clients that no other attorney in Oklahoma can offer!
