​"Mark is incredibly thorough. He always has documentation to back up what he says, never shoots from the hip without facts.  He’s eager to help and very accessible. He makes it easy for those of us in the media to verify what he is saying is true." 


"Mark’s deeply committed to staying up with the latest trends re: his field and always does his homework before reaching out to speak on an issue. He’s in it for the right reasons, to improve public safety and help those of us in the public gain a better understanding of the problems that are impeding that goal."



Testimonial: Joseph T. Williams (Partner) Williams & Santoni |


"I was very lucky to find Mark McDonald and his company, NatGas Consulting, after being retained by the family of a person terribly injured in a natural gas explosion.


I knew nothing about natural gas or the cause of the explosion. I told Mark that I wanted to know the truth, even if the truth proved harmful or even fatal to my case. Mark told me that the truth was all he would give me. I was pleased to learn that Mark was a man of his word.


Mark jumped on the case immediately and reviewed all available information, much of which I was unaware of and very quickly told me about the cause of the explosion.  He explained what had happened and how he was able to arrive at his conclusions. He was crucial to my understanding of the facts.


If I have any matter involving natural gas or anything remotely related in the future I will involve Mark's company immediately. I recommend NatGas and Mark in the highest possible terms to any lawyer or insurer wanting to get at the truth".
