We asked our 2022 graduates to share their most memorable moments at Barrow, the advice they would give to their younger selves on their first day of training at the Institute, and which people at Barrow served as their biggest influences. We’ve compiled their responses below.

Neurosurgery Residents

Jacob Baranoski, MD

New role: Endovascular Surgical Neuroradiology Fellow, Barrow Neurological Institute, Phoenix, Arizona

Jacob Baranoski, MD
  1. While there were certainly many memorable clinical moments during my time at Barrow—clipping my first aneurysm, etc.—my most memorable experiences have been the team building and camaraderie events, including hiking the Grand Canyon Rim to Rim and winning the softball tournament.
  2. The advice I would give to my younger self on my first day at Barrow would be to enjoy every minute of it—the seven years will go by quick. It won’t always be easy, but extract everything you can out of each moment.
  3. The entire Barrow family was influential, including the attendings, co-residents, RNs, office staff, and others. Each and every person contributed to a wonderful experience.  

Tyler Cole, MD

  1. My most memorable moments at Barrow were the group residency activities like the Hike from Hell, Grand Canyon trips, the annual charity softball tournaments, and all the other activities we have that get people together.
  2. The advice I would give, and try to follow, is to constantly compete with yourself, make at least a small improvement every day, and don’t get caught up in comparing yourself to others.
  3. I’ve been most influenced by the younger residents. As we move up to senior resident, and then chief resident, there’s more responsibility and management duties that we take on. Trying to grow into a position where people respect you for your ability to help them improve is more challenging than leaning on rank or authority to receive that respect; attempting to pursue the former has pushed me to improve in ways I hadn’t even considered just a few years ago.

Colin Przybylowski, MD

New role: Neurosurgeon, Raleigh Neurosurgical Clinic, Raleigh, North Carolina

  1. My most memorable moments at Barrow were winning three straight softball championships in New York City and participating in the Barrow Olympics and golf outings with residents and attendings.
  2. The advice I would give to my younger self on my first day at Barrow would be to stay true to yourself.
  3. The people who influenced me the most at Barrow were Dr. Nader Sanai, Dr. Kris Smith, Dr. Randall Porter, and Dr. Steve Chang.

Christina Sarris, MD

New role: Pediatric Neurosurgery Fellowship, Children’s Hospital of Philadelphia, Philadelphia, Pennsylvania

Christina Sarris, MD
  1. My most memorable moment at Barrow was placing my first external ventricular drain independently, performing my first orbitozygomatic craniotomy, and attending and hosting Barrow social events.
  2. The advice I would give to my younger self on my first day at Barrow would be: Don’t be afraid to push yourself out of your comfort zone—you are so well-supported and encouraged by everyone at Barrow. These seven years are your chance to learn and grow as much as you can.
  3. The people who influenced me the most at Barrow were Dr. Andrew Little for instilling in me a love of endoscopic skull base surgery and desire to improve patient care, Dr. Michael Lawton for challenging me technically, and Dr. Ruth Bristol and Dr. David Adelson for instilling in me a love of pediatric neurosurgery.

Neurosurgery Fellows

Christopher Graffeo, MD

New role: Assistant Professor in Skull Base and Cerebrovascular Neurosurgery, Co-Director of Adult Brain Tumor and Cerebrovascular Programs, Director of Medical Student Education; University of Oklahoma Department of Neurosurgery; Norman, Oklahoma

cerebrovascular fellow christopher graffeo
  1. Although the spiritual elevation of completing the Rim-to-Rim hike was a truly singular experience, I’m not sure anything will be more memorable than the first time I encountered—and, more importantly, successfully controlled—an intraoperative aneurysm rupture.
  2. The advice I would give to my younger self on my first day at Barrow would be: There’s a decent gym in the hospital basement, there’s a very dark call room with a respectable bed by the OR, and Taco Boy’s is open until 0100.
  3. It would be impossible to overstate the extraordinary influence my mentor, role model, and now friend Michael Lawton has had on me during my fellowship, and will continue to impart as I transition from trainee to junior faculty and beyond. You’ve made me a braver and more thoughtful surgeon, and I’m as grateful for the moments when you encouraged my weirdness as I am for the times you checked it—thank you. In tandem, many of the richest experiences I’ve had this year have been shared with my co-fellow Visish Srinivasan, with whom I’ve forged a lifelong bond as trail companion in exploring and expanding the cartographer’s maps.

Gennadiy Katsevman, MD

New role: Neurosurgeon, Neuroscience and Spine Associates, Naples, Florida

  1. The entire year was filled with memorable activities, including the discussion of complex cases at spine rounds, learning new techniques in the operating room, and traveling to various meetings across the country.
  2. The advice I would give to my younger self on my first day at Barrow would be to soak it all up, take advantage of all the incredible opportunities at Barrow, and learn from everyone.
  3. The person who influenced me the most at Barrow was my mentor and fellowship director, Dr. Juan Uribe, who continually pushes the boundaries in patient care and research as he strives for excellence and perfection. In addition to Dr. Uribe, my year would not have been possible without Dr. Uribe’s incredible practice coordinator, Briana Becker, who is the “backbone” of the fellowship year and who taught me about the nonsurgical aspects of running a busy, successful clinical practice. Lastly, I would like to thank my co-fellow Dr. Clinton Morgan, who helped make this year enjoyable and educational.

Visish Srinivasan, MD

New role: Assistant Professor of Neurosurgery, University of Pennsylvania, Philadelphia, Pennsylvania

Visish M. Srinivasan, MD
  1. My most memorable moment at Barrow was rounding the next morning on a stroke patient who had a completely normal exam after I performed a thrombectomy independently.

  1. I don’t know if there is one memorable moment that I can speak to, but I will always remember the great people I have gotten the opportunity to work with, both in the neuroradiology/radiology department and the rest of the hospital. The collaborative spirit and enthusiasm they brought to work has made each day a joy to be here.
  2. The advice I would give to my younger self on my first day at Barrow would be that coming in as a fellow is a little different than starting as an intern, since you have some more experience to rely on starting out. However, I felt very fortunate that all the neuroradiology staff and current fellows who completed their radiology residency here were so willing to help make the transition as smooth as possible.
  3. The person who has had the most influence on me this year at Barrow was Dr. Roger Bird. I think that most of the neuroradiology fellows have probably felt that way over the years, but his passion for the program and care for the fellows has really helped me to grow not only as a radiologist but also as a person. I’m truly grateful that I had the opportunity to complete my fellowship here at Barrow and will cherish the time I spent with the amazing people who work here.
