Do you accept cases nationwide?

Yes, my practice is nationwide.

What kind of cases do you consult on?

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.

Do you work for the plaintiff, or do you work for the defense?

I work for both plaintiff and defense lawyers on civil and criminal cases.

Are you licensed to practice engineering?

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.

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.
