There are 3 fellows each year with their own areas of interests and plans for the future. The program gives them a firm grounding in general cardiology, but also allows them the flexibility to focus on a specific sub-specialty, if desired.
A Word from Our Chief Fellow, Jesse Fitzpatrick
Thank you for taking the time to learn about our program. What drew me to the KPNC Cardiology Fellowship was the tremendous investment placed in each fellow’s professional development. All aspects of the program are designed with education in mind and the leadership is very receptive to feedback. Whatever your individual goals, Jonathan Zaroff and the faculty will move mountains to get you there. Clinical volumes and exposure to rare pathology are excellent as all 4.3 million Northern California Kaiser members are funneled through our two cardiovascular training sites. The Division of Research has some of the largest research databases in the world and houses leaders in the fields of clinical informatics, epidemiology, and health care delivery science. Perhaps the most unique aspect of our program is the collegiality between our fellows and faculty. Whether it be a pickup basketball game, happy hours, or returning Dr. Zaroff’s wicked pickleball serve, everyone at KP is interested in your life and family outside the hospital.
If you choose to join our program you will receive outstanding preparation for a career in general cardiology or a solid foundation on your path to sub-specialty training. Our fellows have secured desirable employment opportunities and/or positions in advanced training programs both in the Bay Area and around the country. I look forward to meeting you and please reach out if you have any questions!

Career Aspirations
I have multiple areas of interest within cardiology including advanced heart failure, cardiac imaging, and general cardiology. Outside of my clinical work I am passionate about understanding how to improve patient outcomes and how this can best be accomplished by changes in healthcare delivery. I want a career where I can continue to work with residents and fellows after I have finished training.
How I Thrive
I like to recharge by spending time in nature. My wife and I enjoy rock climbing, backpacking, and skiing. We recently have branched out into traditional rock climbing where you protect the route using CAMs and nuts instead of bolts placed in the rock. I am also an avid home brewer and enjoy exploring new beer recipes with friends.
What I Like Best about the Fellowship
Everyone is excited to be coming to work and enthusiastic about fellow education. The patient/procedural volume is fantastic and Kaiser has some of the largest patient databases in the world for clinical research.

What I Chose This Fellowship
I chose Kaiser to pursue my cardiology fellowship because the people I met on my interview day were both genuine and caring. Growing up and training in New Mexico, I knew that if I left for fellowship, it would have to be to a place that not only supported my career goals, but more importantly, treated me like family. After my interview day, I knew that Kaiser was that place. I knew that I would get excellent training in a welcoming environment, surrounded by individuals who cared about me as a person and not just as a trainee. I can’t wait to get started!

Moreover, after spending time at Kaiser SF, I had the opportunity to work with the knowledgeable and passionate faculty, experience the collegial and supportive environment, care for the diverse patient population, and witness a wide array of pathologies. The program prioritizes fellow education and fosters fellows’ growth so it was clear to me that this is where I wanted to be!

1st Year Cardiology Fellow

Diana Tobler, MD
1st Year Cardiology Fellow
UNDERGRADUATE
Sonoma State University
MEDICAL EDUCATION
Oregon Health and Science University
RESIDENCY
University of California, San Francisco
CAREER ASPIRATIONS
I am interested in general cardiology, heart failure, and pulmonary hypertension. Outside of my clinical work I am passionate about understanding how to improve patient outcomes and health care delivery, specifically as it relates to patients who are traditionally underserved in our current healthcare structure.
HOW I THRIVE
I live my best life through staying active and traveling. I love running and hiking and recently got a dog who is always looking for an adventure and makes sure I don’t slack off! I love to travel as a way to experience different cultural and natural perspectives and of course to make new connections. I usually try to travel internationally, but during the pandemic I am embracing local traveling and camping more.
WHAT I LIKE BEST ABOUT THE FELLOWSHIP
Patient care is everyone’s top priority, and fellow education and experience come in a close second. Everyone is working hard to ensure patients receive the best care possible, which is easy to do in such an integrated and collaborative system. Staff and leadership are also deeply invested in fellows having the richest educational experience possible; the program is small enough for the experience to be individualized but large enough to be collaborative and supportive.
