Meet the team that delivers a personal touch to go along with leading neurodiagnostics expertise:
Olivia Fisher, CNIM
Founder, President and CEO
Plenty of changes have occurred during Olivia’s two decades of experience in the neurodiagnostics field. In that time, she’s observed IONM not only becoming an integral part of surgeries, but growing in its application. After learning and practicing IONM for 10 years at the University of Kansas Medical Center, she joined a small IONM startup where she learned the ins and outs of traveling and practicing IONM for multiple hospitals across the Midwest. She then branched out on her own to provide IONM expertise starting with two surgeons at a single hospital. As the demand grew for providers of quality neurodiagnostics, she had to expand and hire other technologists to meet this need.
Today, nearly 15 years at the helm of Seastnan, she and her team currently cover cases at over 20 hospitals in Kansas City and the surrounding areas – with demand continuing to grow. It has been important for her to grow Seastnan carefully at first with a real focus on quality. With a solid foundation in place, the company she envisioned is becoming a reality. Her favorite thing about her job? Combining the entrepreneurial side of growing her company, while still being able to practice clinically and discovering new ways IONM can benefit patient outcomes.
Free time-funny! With three high schoolers and one in college, Olivia continues to find the joys of a thriving family and business. Oh yes, and squeezing in a few games of Mahjong with friends where she can.
Callan Broderick, MS, CNIM
Director of Education
Callan obtained her Master's of Science in Biomedicine with an emphasis in Human Anatomy from Colorado State University. Callan has IONM experience both on the national and in-house level, and in 2019 she started the Trainee and Advanced Clinical Education Program at Seastnan Medical, which was recently accredited by ABRET as a Formal IONM Program! In addition, Callan was elected and will join the distinguished few on the ASNM Board of Directors in 2025. Callan enjoys training and teaching brand new neuromonitoring professionals as well as helping seasoned CNIMs gain experience and confidence on rarer, more complex cases.
Callan herself also regularly monitors surgical procedures, with her favorite cases being complex intracranial tumor resections. When not in the OR or leading educational sessions, she keeps busy with her family, enjoying her garden and going on family hikes.
Josh Wise, CNIM
Director of Clinical Development
Josh attended the University of Michigan and was one of the first graduates of its IONM program. He began his career in New England where he worked for 7 years before relocating to Kansas City and joining Seastnan Medical. Josh takes an active role in the clinical training of incoming hires and finds it rewarding to see their progress from day one in the operating room to becoming a fully independent member of the team. He is also involved in maintaining quality assurance to ensure that we are providing the best quality of care to our patients, surgeons, and hospitals.
In his free time, Josh enjoys spending time with his family, being active, traveling, and exploring local KC coffee shops.
