About us



An Ounce of Prevention is my company and equipping others with invaluable skills is my mission. Teaching CPR classes in Seattle is how we help Washington employers meet OSHA requirements every year. Every person who leaves our classroom takes with them the ability and confidence to save a life. Whether you need the certification for your job or simply want the skills to be a prepared parent or community member, An Ounce of Prevention has the CPR Class in Seattle for youNo matter what your motivation, the potential outcome is the same. In a single moment, you can save a person’s life. When you save one person’s life, you spare their friends and family from heartache and you protect that person’s branch on the family tree. All that in an instant — with skills you can learn in a few hours.

Our CPR classes in Seattle start with video based learning, so you can see techniques presented in real world scenarios. We have top of the line equipment to properly train you, from adult and baby resuscitation mannequins to fully functional AEDs (Automated External Defibrillators). Class sizes are traditionally small, so you get the personal attention necessary to learn, practice and master techniques quickly and efficiently. Our classrooms are in the SoDo district of Downtown Seattle, just south of the old Rainier Brewery on Airport Way South where I-5 meets the West Seattle Bridge. We also offer in-home private classes and workplace training anywhere in Greater Seattle, the Eastside and Tacoma. For convention audiences, we offer engaging, inspiring and interactive presentations with easy-to-follow take-home materials.

Founder, Lead Instructor, Presenter

I began my career as a paramedic where we responded to medical emergencies every day. I remember seeing the look of helplessness on parents’ faces time and again as we would arrive on scene – the fear of making an already dire situation worse by doing the wrong thing when a child stops breathing. Empowering parents was the reason I started teaching CPR classes in Seattle.

I have dedicated the last 22 years of my healthcare career to working as a trainer, educator and practitioner in various Emergency Departments, cardiac floors and employee wellness programs.

I’ve taught lifesaving techniques at community centers, senior homes and hospitals for a few years before moving from Florida to Seattle to be closer to family. Once settled, I taught CPR to staffers at all the top hospitals in town (including Harborview, Virginia Mason and Swedish). An Ounce of Prevention began as a part-time endeavor in 2001 to better reach parents, nannies and babysitters. In 2006, An Ounce of Prevention became a full time business, with a full roster of certified teachers offering more than 30 classes per month in English and Spanish. We also manage on-site workplace trainings and in-home private classes for parents and their household staffs.


As a convention speaker, inspiring people in a wide variety of industries to become CPR and First Aid certified. During my engaging and interactive seminars, groups commonly ranging from 50 to 100 people can learn key life saving techniques in a fun and engaging way.

I love to help parents create Kid Safe Environments at home. With helpful tips and product recommendations, you can “Baby Proof” or “Childproof” your home in an afternoon. This will prevent many common accidents ranging from minor cuts and bumps to potentially fatal falls, electrocution, drowning and poisoning.
