I've been a patient of Dr. Slezka for over 21 years and this appointment was the first time I've seen him in several years. I realize he is extremely busy and even though his PAs have been wonderful caregivers, it was a real pleasure to see the Doctor who has been a hero IMO for me since he first took me on as his patient. Watertown area is extremely fortunate to have him as the leading cardiologist in the our north country area and I have nothing but praise for his continued service for our locality.

I developed Cardiomyopathy at the age of 31 , Dr Slezka has been my cardiologist for 10 years. For something absolutely terrifying and almost life ending, this provider gave the care compassion and understanding throughout having a pacemaker defibrillator placed in 2016 to getting me so well I was able to have this removed and NOT replaced last year - if I could rate him 100 stars here I would along with the rest of St Joes. Excellent care !!! I give permission to please share with anyone , I work in healthcare and kind comments are hard to come by some days.
