Expert reports, deposition, and testimonial services

I am a media trained security expert that has developed hundreds of reports and articles, that are visually aesthetic and impactful.

 

I have given hundreds of presentations and executive briefings. I have an expansive career where my reports, presentations have been a proximate reason for change within organizations.

Here's how it works

Site analysis includes evaluation of existing conditions, including crime prevention through environmental design, architectural keying, locking, other architectural programs, security technology, function and operation, operational security, such as policies procedures, training, pre-employment processes/criminal background investigations.

Upon request and with an agreeable schedule, I can facilitate emergency mobilization site evaluation.

On site I can facilitate the discovery of additional information, which can include light metering, site documentation, and interviews with residential or businesses in the surrounding area.

Have questions?

What does an expert witness do?


Once retained, a premise liability/security expert witness is obligated to truthfully and with integrity review, advise, investigate elements of the case, discover new information and provide direction. When requested to do so, the expert, based on the information received, will author their opinion in a report or verbally in a deposition or trial.




What qualities do I need in an expert witness?


A security expert should love what they do, have attention to detail, excellent written and oral communications skills. Presentations and article or book contributions or authorship will typically evidence this. They should have recent or current experience in the area they are being retained.




When should I hire an expert witness?


Ideally, as soon as possible. The longer you wait, the more chance that environmental conditions will change at the site where the loss occurred. Complicated negligence, premise liability cases should necessitate the immediate engagement of an expert witness. The purpose is to assist with validating information and or help obtain new information. Alternatively, a subject matter security expert should be engaged if opposing council discloses they have retained an opposing security expert.




Where do you practice your security expert witness work?


I work all over the United States, but am based in Chicago, Illinois.




My expert wants to conduct a site visit. Do expert witnesses really need to do a site visit?


The opposing counsel will always ask "have you visited the site", and "how can you render an opinion for something you have never seen". So, the answer is ideally, as soon as possible. The longer you wait, the more chance that environmental conditions will change at the site where the loss occurred. The International Association of Professional Security Consultants (IAPSC) has a guideline that addresses forensic methodologies. Get it here
