  2. I participated in the Black Hawk, Colorado Stair Climb this morning. The wrist band that was given me to wear had the name Dennis O’Berg on it. I found his picture on the wall of the stair well during the climb. As I looked at his picture on the wall, tears came to my eyes as I could not help but think of the sorrow his parents must have felt. I will always remember this day, the honor of wearing the wrist band with his name on it and his picture on the wall. He and all of those men along with their families will always be in my thoughts. God Bless them all!

  3. This past weekend, September 10, 2016, I had the privilege of climbing for Dennis P. O’Berg at the 9/11 memorial stair climb at Lambeau Field in Green Bay, WI. As I got closer to the equivalent of the 78th floor, I got so emotional. As I ran the bell for him, it was hard to say his name. Thoughts and prayers are with your family. You will never be forgotten!

  5. I had the honor of climbing for Dennis O’Berg today, 9-16-17, ringing the bell for him was a privilege and I thank his family for giving us a hero! Not only did I wear his badge with pride I read the signs they set up as the events of 9/11 unfolded which made it more real for me. I will always remember that day! I was in high school in my civics class when they flipped on the tv and my jaw just dropped.. all those innocent people.. the courage it must have took to enter the trade center building! I hope I honored your memory Dennis! I will most definitely be back next year to honor another fallen hero!! God bless America and all our fallen heroes!! ??

  10. I was Dennis’ manager at Ernst & young and he was such a kind heart & every year on 9/11 I have tears for him & I say a prayer for him. He told me that his dream was being a fireman & not a CPA & he lived his dream. God bless him & his family. He’s not forgotten by the people he touched.
