Bio
Fabiano Assi
David approached our company for a tremendous project which served the LED industry. During the multiple exchanges we had for the project I learned a lot from the skills and experience David had in the entire sapphire and LED manufacturing chain. He is a talented, hard-working and warm co-worker and a joy to collaborate with. Later I met David in additional sapphire projects were he continuously brings in a lot of knowledge and important background information.

I have known Dr. Callejo for two years and have seen his ability to develop and improve crystal growth processes first hand. Dr. Callejo brings as much knowledge and experience to the science of crystal growth as anyone in the field. David is also a joy to work with. David communicates well with all levels required to be successful in the business of crystal growth. David can give clear direction to the crystal growth operator, listen to their concerns and at the same time David has the knowledge and ability to discuss the sophisticated technical challenges that frequently accompany crystal growth problems. I can enthusiastically recommend Dr. Callejo to understand and solve even the most difficult crystal growth problems.
