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 IOM not only becoming an integral part of surgeries, but growing in its application. After learning and practicing IOM for 10 years at the University of Kansas Hospital, she joined a small IOM startup where she learned the ins and outs of traveling and practicing IOM for multiple hospitals. She then branched out on her own to provide IOM expertise to two surgeons at a single hospital.

Today, nearly eight years at the helm of Seastnan, she and her team currently cover 13 hospitals in the Kansas City area – with demand continuing to grow. 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 IOM can benefit patient outcomes.


Nicole Watson, R EEG T, CNIM
Executive Director

In her role as Operations Manager, Nicole credentials technologists and works with surgeon’s offices and hospitals to manage scheduling needs and maintain inventory, among other key duties. Her experience in neurodiagnostics began in 2007, where she worked in the outpatient EEG lab at the Cleveland Clinic in Cleveland, Ohio, then transitioned over to the Epilepsy Monitoring Units (EMU) in both the pediatric and adult worlds at Rainbow Babies and Children's Hospital, and University Hospitals of Cleveland. After working as an R EEG T at The Ohio State Medical Center, where she ran the University’s first Neurovestibular Lab for two years, Nicole moved to Kansas City to become an in-house intra-operative neuromonitoring technologist at Children's Mercy Hospital.

Now at Seastnan, Nicole’s favorite aspects of her job are getting to work with such diverse groups of people, and being an integral part of each patient's improvement of their health and well-being.


Callan Broderick, MS, CNIM
Director of Education

As part of the Seastnan team, Callan recruits and trains new technologists in Intraoperative Neuromonitoring and helps them gain certification. Before joining the company, she trained in Neuromonitoring with a large company in New England, then relocated with her husband to Kansas City to accept an in-house Neuromonitoring position at the University of Kansas.

In her role at Seastnan, Callan loves the daily variety of cases and locations, and always finds the work interesting and stimulating. The delicacy of the human nervous system never ceases to amaze her. Being able to precisely monitor a patient’s ability to hear, move, and feel sensation intraoperatively, and provide feedback to the surgical team is very fulfilling.
