Advanced Professional, Technical, and Educational Achievements

  • National College DUI Defense, Inc., Advanced DUI Training and Continuing Education
    Summer Sessions 1998, 1999, 2000, 2002, 2003, 2004, 2005 taught at Harvard Law School, Cambridge, Massachusetts. Winter Sessions, 2002, 2003, 2004, taught in Biloxi, Mississippi, San Antonio, Texas, and San Diego, California. This is the most advanced DUI practice course offered to a limited number of attorneys (approximately 120/year) throughout the United States. It consists of training based on a given factual scenario which each attorney is required to prepare for trial, opening statements, cross-examination of arresting officer; cross-examination of the State or Government's expert witnesses; presentation of exculpatory evidence on behalf of the defendant; and closing arguments, which are critiqued by very top DUI attorneys and instructors from across the United States.
    Trial practice training, conducted in small groups, is supplemented by presentations and lectures by top scientists, law enforcement trainers, criminal defense lawyers, jury consultants. Student/attendees work in groups with scientists and criminalists who explain the inner workings and advanced scientific developments regarding chemical blood, breath, and urine testing using the same devices and instruments used in their own states or jurisdictions, such as the Intoxilyzer.
  • Certified Practitioner, NHTSA/IACP Standardized Field Sobriety Tests
    Jeffrey Siirtola is a certified practitioner of the three standardized field sobriety tests, including the horizontal gaze nystagmus (HGN) test; the Walk and Turn (W/T) exercise, and the One Leg Stand (OLS), following completion of the same three day (24 hour) course and alcohol workshop for practicing tests with live human subjects dosed up to different alcohol levels, taught and supervised by Master Law Enforcement Instructors from the State of Texas.
    Few driving under influence defense lawyers have gone through and been certified in this law enforcement training.
    The course is based upon the law enforcement Training Manual and curriculum developed by the U.S. Department of Transportation, and upon a scientific study done for DWI Detection and Field Sobriety Tests in San Diego, California, including protocols for detecting possible alcohol-impaired drivers by their driving behaviors (driving evidence); by officer observations of subjects from time subject vehicles pull over to right hand side of road until subjects are asked to step out of their vehicles (observation evidence); by proper administration of three standardized field sobriety tests (SFST'S)(field test evidence), resulting in arrest and the administration of chemical tests of breath, blood, or urine.
  • Breath Alcohol Testing (BAT) Certificate, Operator Intoxilyzer 5000
    In 2003, Jeffrey Siirtola became the first lawyer in the State of Arizona to purchase his own Intoxilyzer 5000 evidential breath testing device, then obtain operators training on the device outside the State of Arizona. The Intoxilyzer 5000 is one of two breath testing machines or devices used in Arizona for evidential breath testing of persons arrested for DUI under the Implied Consent Law. The machine is manufactured by CMI in Kentucky, and is the predominant machine used throughout the United States for breath testing.
    Few driving under the influence lawyers have gone through and been certified as operators of this device under national U.S. Department of Transportation standards and the Code of Federal Regulations.
    This course taught how to operate the device, how to conduct valid breath tests on human subjects dosed up to various levels of alcohol; scientific and technical aspects of breath alcohol testing, including photo-spectroscopy, the internal parts and workings of the Intoxilyzer 5000; minimum factory recommended maintenance standards for proper maintenance and operation of their machine.
  • Breath Alcohol Testing (BAT) Certificate, Field Maintenance/Quality Assurance Specialist, Intoxilyzer 5000
    Most law enforcement personnel in the State of Arizona are trained to operate the Intoxilyzer 5000 breath testing device. Only a small number of law enforcement personnel are certified to conduct maintenance procedures, such as monthly calibrations, however, on the Intoxilyzer 5000 breath testing device.
    Mr. Siirtola is certified to federal U.S. Department of Transporation standards under Code of Federal Regulations to do field maintenance procedures and factory-recommended minimum preventive maintenance procedures on the Intoxilyzer 5000.
    Only a handful of attorneys own their own Intoxilyzers and/or have maintenance certificates and the ability to conduct and critique performance of maintenance procedures based on their own hands-on training on the devices to national factory recommended maintenance standards, as opposed to lesser state administrative maintenance standards.
  • Certified Instructor, Breath Alcohol Testing (BAT), Intoxilyzer 5000 Operator Course
    Mr. Siirtola recently served as an adjunct instructor (technical/laboratory instructor) Intoxilyzer 5000 operators course taught to national U. S. Department of Transporation/CFR standards with law enforcement and medical faculty/personnel in West Palm Beach, Florida.
  • Certified Phlebotomist/Medical Blood Draw Technician
    In Arizona, small numbers of law enforcement personnel have received training in how to draw blood in clinical settings, have received certificates within their departments to conduct blood draws on possible driving under influence subjects, and are conducting blood draws to lesser, non-medical standards in field situations.
    Mr. Siirtola recently went through training in proper medical procedures for conducting blood draws, taught to medical standards, and received a phlebotomy certificate, and received a Training Manual for minimum safe and appropriate medical standards for blood draws taken from human subjects, after passing an examination and successfully conducting blood draws to proper standards on human subjects.
    On information and belief, Jeffrey may be the only driving under the influence lawyer in Arizona to have gone through medical training for blood draws, and to have obtained a certificate from a medical continuing education service provider as a phlebotomist.
    There are sometimes problems with how police phlebotomists collect blood; store blood samples; and analyze blood that result in inaccurate or useless numbers for blood alcohol test results, which can be discovered and, if discovered by a knowledgeable defense laywer, used to advantage in a blood evidence case.
  • BAT (Breath Alcohol Technician), Operators Certificate, Intoxilyzer 8000
    The Intoxilyzer 8000 is a new and novel evidential breath testing device being used in the State of Arizona and, at the time of this writing, only five of the other forty-nine other states. The State of Tennessee recently de-certified the device for law enforcement use in Tennessee, because it failed to perform as well, having less accurate and precise breath test results, than the device it was supposedly designed to replace, the Intoxilyzer 5000.
    Mr. Siirtola recently completed a multiple day operators course taught to U.S. Department of Transportation (DOT) standards on the Intoxilyzer 8000 device at or near Memphis, Tennessee.
    He may be the only, or one of a handful, of driving under influence lawyers in Arizona, who have training and certificates for the Intoxilyzer 5000, the Intoxilyzer 8000, the NHTSA/IACP Standardized Field Sobriety Tests (SFST's); and Phlebotomy Procedures (blood), and who has conducted trainings on the Intoxilyzer, as an instructor.
  • Expert Certification/MCLE Presentations
    Mr. Siirtola has been qualified as an expert witness on breath testing by a number of courts.
    Mr. Siirtola has been asked by his peers (and accepted invitations to lecture/provide training to other driving under the influence of alcohol/drugs lawyers), on subjects regarding breath testing and attacking breath test results, and proper maintenance procedures for the devices in Arizona and other states, including:
    • Arizona

Head (Georgia) and Mr. Charles Sifers (Oklahoma) on the Intoxilyzer 5000 using national CMI Intoxilyzer 5000 factory-recommended maintenance guide/standards as primary source material and using live Intoxilyzer 5000 for demonstrations to practice group.
    • Florida
