Testimonials

I have known Trevor Ellis and his firm, Ellis International Services, Inc., for 30 years and have had the pleasure of working with him regarding many projects involving mine property appraisal and valuation. Trevor has always exemplified the highest ethical standards while completing even the most challenging projects within demanding deadlines and at a fair and reasonable cost to his clients.

- Jack M. Merritts

As our expert you were able to provide tremendous assistance in educating us, and the court, concerning the different qualities of the rock, its age, the location of granite seams, [and] the amount of granite gneiss on the site. Your thorough, hands on inspection of the site, your tremendous knowledge of geology and the mining industry, and your thorough preparation, in my opinion, created the foundation of our recovery.

- R. Bartley Halloran

Your work ethic was exemplary and your honesty and integrity in your work product beyond reproach. Because of your help we were able to obtain the largest eminent domain verdict in the history of the state of Connecticut. If it was not for your assistance in this case, I do not believe we would have achieved the tremendous result we obtained for our client.

- James J. Skelton

My clients and I are extremely pleased at the result, as we achieved a result that could not have been surpassed had we concluded this matter in court…Your work in this case and deposition testimony certainly aided our ability to achieve such a favorable outcome…. I am sure that your testimony was instrumental in our efforts to convince CSSI to settle on our original terms.
