An affidavit is a concise sworn statement addressing a narrow technical question. When a case requires a formal engineering opinion without a full analysis, Mark provides a focused, court-ready declaration summarizing his technical findings in a clear and legally defensible format.

An expert witness report is a full written analysis of the technical evidence in a case. Mark’s reports include his qualifications, all materials reviewed, detailed engineering analysis, and clear conclusions supported by data, figures, and photographs where needed.

Mark thoroughly reviews all case materials before deposition or trial to ensure he is prepared to defend his opinions under oath. He presents complex electrical and telecommunications findings in plain language that judges, juries, and opposing counsel can follow and challenge.

A post-trial evidentiary hearing occurs when new evidence surfaces after a verdict has been rendered. Mark analyzes newly obtained technical evidence and provides clear engineering opinions on its relevance, helping attorneys and the court understand what the new findings actually mean.

Appeals often arise when a convicted individual challenges the technical basis of their case. Mark re-examines engineering evidence from the original trial, identifying methodological flaws or overlooked facts (if there are any) and provides an independent technical assessment for appellate attorneys and the court.

Mark McFarland has worked on several cases across the whole country. You will not find a more qualified expert witness for your case.
Mark was great to work with. He simplified some complicated issues so everyone could understand the facts. He was available when we needed him, and he met all of our deadlines. This case settled in our favor after Mark issued his expert report. Highly recommended!

Yes, my practice is nationwide.
My practice covers various cases involving electrical, electronic, or telecommunications phenomena.
I work in both civil and criminal cases for the plaintiff or defense.
I have worked with plaintiff and defense lawyers on civil cases in several fields, including wrongful death, personal injury, product liability, medical malpractice, class action, insurance claims, auto accidents, contract disputes, and more.
Some criminal cases I’ve worked on have involved securities fraud, homicide, sex trafficking, and home invasion. The criminal cases usually center around cellular, mobile phone, GPS, and other electronic evidence.
I work for both plaintiff and defense lawyers on civil and criminal cases.
Yes, I am a licensed and Board certified engineer. My Board certification comes from the National Academy of Forensic Engineers. Additionally, I am an NCEES “Record Holder, ” meaning I can typically get licensed in any state within 30 days.
I am accepting new cases and am flexible and available on my clients’ schedules. I take pride in meeting all my clients’ deadlines.
My rates are very reasonable. I have two set rates for testimony time, such as in deposition or trial. The second, a lower rate, is for all other time (research, report writing, etc.) I collect an initial retainer and invoice against that.
I’ve been blessed with the opportunity to gain excellent academic credentials.
I have a Bachelor of Science in Electrical Engineering (BSEE) from Lehigh University in Bethlehem, PA. My first Master’s degree is in Telecommunications Engineering, and my second Master’s degree is in Engineering Management- both from the University of Colorado at Boulder. I also completed about 2/3 of an MSEE degree in RF engineering from Drexel University in Philadelphia before moving to Colorado.
Lastly, I procured the highest credential available in the quality sciences: the Six Sigma Master Black Belt. This required eight graduate courses (24 credit hours) in applied statistics and research at the University of Colorado.
I have over 25 years of experience as an engineer and ten years of experience in quality sciences and applied research.
Yes – I have testified on behalf of the plaintiff and defense at criminal and civil trials.
