Lived on Cedarcroft Road then in August 1963 moved to Jodyway in neighborhood of Valleywood in Timonium as the family was expecting their 4th child.

The Hasslinger's always made me feel welcome in their home when I was a young boy.
One of my most cherished memories is of listening to records with Greg in Mr. Hasslinger's studio.

I haven't forgotten those days. I think of your Dad & Mom fondly. So sorry for your loss.

Take Care.

I also took piano lessons from Mr. Hasslinger from 1964-1976 and because of him and his great teaching and friendship became a professional musician and composer. He was a major part of my life and will be missed.

To the Hasslinger Family sorry for your loss of John Sr. I grew up at 320 Gailridge Roade right behind their house. I always remember for the rest of my life hearing the sweet sound of the piano being played in that house behind mine growing up and how it made life better just beign able to hear that great sound when I was feeling stressed and how it made me feel better.

I took piano lessons from Mr. Hasslinger 48-yrs ago (for 6-years,) riding my bike thru the neighborhood to Jodyway. He was a gem! And so proud of his children and lovely wife. I have fond memories of time spent with him. My thoughts are with his children.
