We are all suffering because we are losing the ones we love. But soon God will wipe out every tear from our eyes. Death will be no more, neither will mourning nor out cry nor pain be anymore (Revelation 21:4). Jesus taught us to pray for God's will to be done here on Earth (Matthew 6:9,10). When God's will is done on Earth, people will not get sick or die because of inherited sin and imperfections. (Isaiah 33:24) Right here on Earth righteous ones will be (Psalms 37:29) and yes, even ones that are asleep in the grave (John 5:28,29) and we can all be together again and will all enjoy the blessings resulting from God's Kingdom rule by Christ Jesus! Until then be strong and take care for my prayers will be with you.

My heartfelt Condolences to The Greg Castillo Family. His integrity and professionalism as a Postal Inspector was excellent. I had the pleasure of working one year with Greg and Charlie Casillas on a special Injury Compensation Team investigating and reporting activities of employees on Injury Comp status. Greg's leadership and expertise led to numerous employees taken off of Injury Comp status and returned to full time work saving the Postal Service thousands of dollars. After retirement we enjoyed Greg's friendship as he joined Postal Manager/Supervisors in monthly Lunch times. May the eternal light shine on upon his soul and may he Rest In Peace. We will miss Greg but we'll never forget him.

I am so sorry for your loss. My prayers go to Terry, Felix. and Gregory. Greg was an inspiration and mentor to me. I will always be grateful for having the honor and pleasure to work with Greg in the Postal Inspection Service from 1990 to 1995. He was the epitome of a professional federal law enforcement officer. Any success I had in my career was surely a product of Greg's training and friendship. We spent many times working together, conducting surveillance all night long, driving to remote towns in central and south Texas, and sharing lots of laughter. I loved listening to his stories about his investigations, and about how much he loved Terry, Felix, and Gregory. Greg was very competitive. I'll always cherish the many tennis battles I waged against Greg and Ted Orona. And, I'll always be envious of Greg's incredible memory - especially for birth dates. He could remember peoples birth dates like now one else. As recent as last year, I reached out to Greg, and as usual, he provided me with some sound advice and guidance. I will miss him tremendously.

I met Greg in San Antonio about 1982 in connection with Inspection Service duties. It was my only personal contact with him. He was very cordial and professional. It was a pleasure to meet and work with this true gentleman.

Thoughts and prayers go out to Greg's family and many friends.
