I endorse this lawyer. Attorney Buckley is an outstanding attorney with an exceptional reputation. He is a strong and zealous advocate for his clients.

John's answers on the AVVO forum are well thought out and usually right on point. I would recommend him for any Criminal Defense work in his area

I endorse this lawyer.

After reviewing attorney Buckley's history as well as his insightful answers to questions posted on Avvo, I believe he is a trustworthy source of legal information and experience.

I endorse this lawyer. John's prior career as a paramedic gives him a unique perspective on how to challenge the chemical tests involved in a DUI charge. John fights hard for his clients and continually looks for weaknesses in the state's case.

I recently called John for some practical guidance regarding how medical professionals handle advance directives (living wills, medical powers of attorney, CPR directives). I am an estate planning attorney and knew that John worked as a paramedic for many years before law practice. John took the time to share his insights and they have been extremely valuable to me as I re-evaluate how to advise clients on end-of-life issues. John is well-respected in the legal community and I recommend him highly.

I am very happy to endorse John Buckley as a true expert and attorney in DUI defense. Unfortunately, what many people facing a DUI don’t know is that there are literally hundreds of attorneys in any metro area who will handle their DUI.
However, maybe only a handful of these attorneys truly know how to defend these complex scientific cases. If you submitted to a blood test or breath test then you need an attorney who has years of formal training and experience defending these complex cases. And no one knows blood test cases better than John due to his years of experience as a certified phlebotomist and SWAT team paramedic.
Rest easy knowing that John has your case. He is one of the top DUI attorneys in Colorado.

John is one of the best people and attorneys I have ever had the pleasure of meeting. I am relatively new to DUI law and he has gone out of his way to help me become acclimated. He has taken abundant time out of his busy schedule to send me important information and/or documents, and he patiently and happily answers any question I ask. He clearly has a vast array of knowledge that can only come from experience and from a true love for what he does. I can only imagine how well he must treat his clients!
