Suzanne Coulston,
General Manager

Suzanne Coulston has 25+ years in management and customer service, which has enabled her to provide the best support available in the heart monitoring services industry today. She is diligent and committed to making sure that each patient, physician and staff member receives the level of service required to get the diagnostic process of heart monitoring started immediately.

Suzanne joined Cardiac Monitoring Services (CMS) in 2001, and helped the company to grow from a mom and pop company to being part of a global leader in the cardiac services field. She works closely with each department of CMS to make sure the customer service is first-class, and the accuracy and turnaround time of each report rises above any competitor. Suzanne is devoted to ensure that each test is treated with the same high level of customer care that a cardiac patient deserves. She regularly wears a heart monitor to find solutions to make the process of wearing a heart monitor easier for each patient.

Suzanne has lived in Orange County, California for the past 30 years and has attended college with a major in Business at Saddleback, and Cal State Fullerton. She is actively continuing her education online, because she feels that in order to grow she must constantly learn. She is happily married and the proud mom to 3 young daughters.
