Previous fellow experiences 

“As you can imagine, the beginning of your cardiology fellowship is a very tense and anxiety-ridden time. One of the things I looked for on the interview trail was an environment that would offset those feelings and make it possible for me to get the best training. When I came to Geisinger the first time, I saw right away that the working environment was very collegial and that the attendings take much pride in the fellows’ education. Our support staff here is phenomenal and the pathology we see is very broad. My experience here has been great.”
– John Ulahannan, MD, cardiology class of 2016

“The ideal cardiology fellowship for me would be a place where I would encounter a large volume and variety of pathology so when I finish my training, I would be comfortable being on my own. Geisinger was the perfect place to meet these wishes. In addition, the education I have received from many well-trained and experienced attending cardiologists has been outstanding. The camaraderie among fellows and staff just reinforced why I chose Geisinger for my cardiology fellowship.”
– Gregory Yost, DO, cardiology class of 2015, interventional cardiology class of 2016

“Geisinger is a comprehensive cardiology program with a balance of a strong clinical approach, extensive research opportunities and a collegial environment that fosters learning. Being the only major referral center in the region, the clinical, procedural, and imaging volumes are ample. This is complemented by an outstanding teaching faculty and state-of-the-art technology. All the attending cardiologists have an open-door policy and are willing to spend the extra time for one-on-one teaching. It is truly a unique place to learn cardiology.”
– Bilal Saeed, MD, cardiology class of 2014, interventional cardiology class of 2015
