I became certified as a Clinical Lipid Specialist (CLS) through the Accreditation Council for Clinical Lipidology as soon as the option was available in 2007, and honestly did not anticipate the benefits at that time.

I have experienced a heightened level of respect and clout from my peers, colleagues, and collaborative physicians – both in the in-patient and out-patient settings. I have been referred patients by other doctors, patients have found me online and scheduled appointments to see me, I get texts or emails frequently with difficult cases from clinicians, I am asked to participate in research, etc. Additionally, I have been invited to speak at multiple conferences around the country with clinicians, researchers, and doctors that I would never have dreamed I would be standing next to as a colleague.

In my career, it has ensued in me a personal responsibility and commitment to continue to learn and maintain an up-to-date level of expertise in the complicated and ever-evolving science of Lipidology to support my use of the title. The National Lipid Association has served as my medical home to fulfill continued education with the organization’s vast array of education, whether online or in person.

In the world of an advanced practice provider collaborating with physicians, it has created a specific and unique niche. While the doctors have to keep up with their imaging and specialty credentialing, this allows them peace of mind that under the care of a certified CLS, their patient’s medical therapy remains optimal for primary and secondary prevention regarding atherosclerotic particles, inflammation, and progressive cardiovascular disease.
