Dr. Harry Mercado was a guest lecturer of the Pioneer group in Oklahoma on several occasions.
It was always a joy to have him!
Not only were his lectures superb, but a delight to visit with.
He had a beaming personality and a gift and love for his work.
My condolences to his family. His colleges have lost a great asset.

I will forever remember Dr. Mercado Sr. He was undeniably the most charming and kind man who was always educating with the most charismatic style. Dr. Senior and his entire family embraced my husband and I for over 24 years. I am thankful for the opportunity to have worked for his practice as well as share wonderful moments with the staff and family. My deepest condolences to all the family. Rest In Peace Dr. Mercado Sr.
