Meet Our Residents
| Hi everyone, my name is Ryan Bosak. I was born and raised in Kings Park, NY. I recently graduated from the University of Connecticut School of Pharmacy in May 2026. I am looking forward to learning how to provide a high level of care for a wide variety of patients while further exploring my areas of interest, which include oncology and critical care. I hope to pursue a PGY-2 residency in oncology. In my free time, you can find me golfing, lifting weights, bowling, or rock climbing. A fun fact about me is that, while playing for the rugby team at UConn, I had to get over 30 stitches! |
| Hi everyone, my name is Bryan Flores! I am originally from Centereach, NY and recently graduated from the University at Buffalo School of Pharmacy in May 2026. I am excited for the opportunity to train at Stony Brook University Hospital and care for a diverse patient population while continuing to grow as a pharmacist. My professional interests include infectious diseases and oncology, and I hope to pursue a PGY-2 residency in one of these specialties. Outside of pharmacy, I enjoy watching soccer, collecting sports and Pokémon cards, spending time with family and friends, and traveling. I look forward to the diverse range of learning experiences and opportunities available at Stony Brook University Hospital! |
Austin Grzechowiak, PharmD | Hello everyone! My name is Austin Grzechowiak, and I'm from Rocky Point, NY by way of Buffalo, NY. I recently graduated from the University at Buffalo School of Pharmacy this past May, and I'm excited to be joining the incredible team here at Stony Brook! One of my long-term goals has been to train at a large academic medical center where I can continue developing my clinical knowledge, strengthen my interdisciplinary collaboration, and grow as a pharmacist providing direct patient care. My current professional interests include investigational drugs, clinical research, cardiology, and neurology. Outside of pharmacy, I enjoy backpacking, hiking, attending Buffalo Bills games, and playing spikeball. I'm looking forward to getting to know everyone, learning from such an experienced team, and contributing however I can. I'm excited for the opportunities ahead! |
| Hey y’all! My name is Chris Mayer and I am from Kings Park, NY. I graduated from the University at Buffalo in May 2026 and I am excited to continue my pharmacy journey at Stony Brook University Hospital. I can’t wait to experience a wide range of complex cases, gain more clinical knowledge, and provide the best possible care to patients. My areas of interest include psychiatry, emergency medicine, and oncology. Outside of pharmacy, I love music (both playing and listening) and spending time with my friends and family. I also love animals and learning new things about them. I am very excited for the experiences and opportunities at Stony Brook. Go Seawolves! |
