Olga Somers
Nurse & RCIS
"I'm an avid traveler, an artist, a business owner, and a registered nurse with about 15 years of experience, most of it spent in the cath lab. I've worked in both Canada, Australia and the US, and I love the pace and teamwork that come with procedural nursing. Over the years, I've found that some of my favorite moments are spent teaching and helping new nurses find their footing. That's what inspired my next chapter: a training program to help new cath lab nurses feel confident and ready from day one. Stay tuned for its upcoming launch."

Zarina Sharalaya
Interventional Cardiologist
Dr. Zarina Sharalaya works in North Texas as an interventional and structural cardiologist. She is board certified in Internal Medicine, Nuclear Cardiology, General Cardiology, and Interventional Cardiology. She is a Fellow of the American College of Cardiology and has served in various leadership roles for the ACC, on the fellows council and the Diversity & Inclusion Committee.

Her clinical interests include complex coronary intervention, transcatheter aortic valve replacement (TAVR), patent foramen ovale (PFO) closure, and she has a special interest in women’s cardiovascular health.
