MMR was founded by Dr. David Krashes in 1961. During the past 50 years, MMR has grown into The MMR Group which consists of three laboratories and approximately 55 employees. The MMR Group employs a number of professionals in a variety of disciplines including materials science, metallurgy, chemical analysis, mechanical engineering, and non-destructive testing. The laboratories are among the leading failure analysis laboratories in the country.

A 1949 graduate of Rensselaer Polytechnic Institute, Dr. Krashes received a Ph.D. degree in metallurgy at RPI in 1958. He is a Registered Professional Engineer in Massachusetts and Delaware. As a professor at Worcester Polytechnic Institute for five years, he taught courses in metallurgy and non-metallic materials, performed research on bi-metallic castings, and helped develop a new metallurgy education program and department. In the early 1960s, he believed that the best way to improve a product was to learn why it failed or wore out in the first place. He was a leader in showing the metallurgical profession that microscopy and electron microscopy were primary tools to use in evaluating failed products, and first began to develop the techniques of failure analysis as it is practiced today.

Additionally, he has developed heat treatments and manufacturing procedures for nuclear reactor fuel elements and control rods, produced the first extruded molybdenum tube, and the first tubes of stainless steels bonded to refractory metals. Technically, he specialized in deterring causes of failures of materials and products and evaluating safety of machines. In 1970, he was significantly honored for his work by being named in the first class of Fellows of ASM (Association Of Materials-Centric Engineers & Scientists) International, formerly American Society for Metals. He has given lectures on determining causes of failures of products, has written a number of articles, and has become widely recognized as an expert failure analyst among metallurgists, material engineers, and the metals industry. He has been a national trustee, the treasurer, vice president, and in 1982, president of ASM International. Additionally, he is also a member of AIME (American Institute of Mining, Metallurgical, and Petroleum Engineers) and ASTM (American Society for Testing and Materials).
