From the Program Director

Welcome, and thank you for your interest in the Special Coagulation Fellowship at Mayo Clinic!

I am Dr. Anil Ashrani, and I have had the honor of serving as the program director since the fellowship’s inception in 2013. Over the past decade, we have been proud to offer a uniquely structured, high-volume training experience that prepares fellows to become leaders in the field of coagulation and thrombosis.

Our program is designed to provide rigorous clinical and laboratory training in both classical and complex coagulation disorders. At Mayo Clinic, you will learn within a collaborative, multidisciplinary environment where expert faculty in hematology, laboratory medicine, transfusion medicine, and vascular medicine are deeply invested in your development. Our program provides a breadth of exposure to inherited and acquired bleeding disorders, thrombotic conditions, hemostatic monitoring, and cutting-edge coagulation testing.

What sets this fellowship apart is the integration of patient-centered care with advanced laboratory expertise. Fellows play a key role in clinical consultations, interpret specialized laboratory tests, and engage in scholarly activity to advance both knowledge and practice in hemostasis and thrombosis. Fellows also benefit from access to Mayo Clinic’s renowned resources, diverse patient population, and a culture that emphasizes mentorship, professionalism, and continuous learning. Graduates of our program have gone on to impactful careers in both academic and clinical settings.

We are proud of the strong foundation our fellowship provides and are committed to training the next generation of coagulation specialists. I invite you to explore more about our program and welcome your interest in joining our community of learners and innovators!
