🇺🇸 Memorial Day at Hex 6 🇺🇸
Today, as a proud veteran-owned business, Hex 6 pauses to honor the brave men and women who made the ultimate sacrifice for our country.
In remembrance of our fallen heroes, Hex 6 Diesel Services will be closed today as we reflect on the freedoms we have because of their courage, service, and selflessness.
We would also like to take this opportunity to thank the Lord for the soldiers and military families who have sacrificed so much in service to our nation. We pray for comfort, peace, and gratitude as we remember those who gave everything.
“Greater love has no one than this: to lay down one’s life for one’s friends.” – John 15:13
Today, we honor. We remember. We are forever grateful. ❤️🤍💙
