Patient Reviews
Jun 19, 2022
Introduced to Dr. Johnston via an Emergency visit to Howard County General Hospital. Shocked to learn I needed an emergency catherization procedure performed several minutes after I arrived. Surprise Surprise! Immediately had the sense after initially meeting him that I was in very good and experienced hands. He performed the procedure to insert a stent to a fully blocked artery. I was conscious during the entire time and never felt any pain. He did a fabulous job and I am feeling great today. Now that I am researching his background to see who he is, I can see that my initial sense was well justified. Thank you Doc! May God Bless you with happiness, health, and long life! Very grateful to have gotten you in the luck of the draw! I must just be a lucky guy.
