It is unfortunate, in OUR professional field, Private Investigators rarely receive reviews. It has nothing to do with the quality of our work, however, I would like to highly recommend Kelmar Global for your investigative need. I have known and been associated with Mr. Riddle for 30 years. Whenever I need professional assistance, I contact Mr. Riddle and he has been there for me. Kelmar Global is "THE" Premiere Texas PI firm. Do yourself a huge favor and contact them today. You can trust their ethics, morals, and integrity. I do. Respectfully, J. Scott Glazener Sr. G-2 Investigations & Insurance Services Texas
