How likely are you to recommend Dr. Lonquist?
Dr Lonquist saved my life. Twice. In 2019 I moved to Pensacola, after loosing my partner in 2018. I was there for two weeks and had an aortic dissection and coded twice. On exactly the same day that my partner died the year before. To say I’ve been given a second chance is an understatement. I remember the exact moment that I awoke and to everyone’s astonishment,asked for something to drink. Without Dr Lonquist and the amazing care I received at Baptist, I’d be with the holy angels right now. I am beholden and eternally grateful. You only live twice is my theme song. With Eternal Gratitude,Kirk Stone.
