Your majestic piano playing was amazing. Your volunteer spirit beyond serving as a Rotary member including ASTD- sharing your talents with many companies and individuals as well as advancing the profession.

My heart goes out to Diane.

David was a brother, partner, friend and inspiration to me. We met at UT-Austin, in 1968. We both worked on a Curtain Club play called "Now the Revolution" (David-music; me-film). It went to Broadway under Joseph Papp, entitled "Stomp." It's still playing today, off-Broadway at the Orpheum Theatre ($200.00), in New York. Then we grew up sorta, and on August 23. 1969 he married this vivacious demure red-head (Diane)—and had the lapse of judgment to make me his Best Man. Well, as life moves us, David & Diane had many adventures and trials along the trail. David & Diane have always been a relationship model for me, sharing love, pain, peace, endurance and abiding Faith to sustain them—and inspire me, too. I will miss my brother, and will cherish Diane for her devotion and strength, and love for David always.

David was a cherished member of the Alamo Heights Class of '65. The bonds we formed continue even today and we all share in the sadness of David's passing. He will be missed greatly by us all and never forgotten.

Diane I am so sorry for your loss. David was such a wonderful, vibrant person, so full of life and love. He was the same in high school as we was all of his adult years. Enthusiastic, giving, achieving.

You are in my prayers and will be keeping you in the light.

My sincerest condolences to Diane and the Flack family. I worked with David at BancPLUS many years ago, but remained in touch with him. So glad we got to see him at our last B+ reunion. He was a joy to work with. I will keep the family in my prayers.

I will always remember David Flack (back in the "BancPLUS" days) as the best instructor of so many important aspects of professional business. Everyone looked forward to being in his classes and enjoyed every minute of his time. I still have every certificate he gave me. He will definitely be missed.

David and I were San Antonio Association for Talent Development chapter leaders for many years in the 90s and had recently reconnected at the 50th anniversary of the chapter's "Party Like it's 1969."
He had an amazing ability to inspire and coach and I learned so much from him. I will miss him.
My fondest memories were when he donned his green and red plaid jacket and played the piano at the SA ATD Christmas parties.

I was introduced to David back in Class III, Masters Leadership Program. We discovered we shared a love for grand opera and have been opera-going buddies ever since. We attended local productions and we made many of the Met matinees at the movies. We shared favorite moments in our CD collections and discovered new artists we had not previously encountered. I will miss David for many reasons, but his love for and devotion to the musical arts will be a great loss to our community. I wish Diane and Martha and all who knew and loved David the very best moving forward without him. I share your grief and have offered thoughts and prayers to help you through this difficult time.

It was back in the BancPLUS days that I have some of the fondest memories of David. We performed a Holiday concert in the atrium of what was then the BancPLUS building. Our choir consisted of employees of various musical experience with David at the helm. The concert was a smashing success. We went on to perform a 4th of July patriotic concert the following year and with that, the tradition was set, two concert seasons a year. David was a person who could inspire, motivate, and with his wonderful smile had a way of showing us to live life at its fullest. I will always remember him. May his memories bring joy to all who knew him.
