Brandon Lamberth, FNP-C

I’m Brandon Lamberth, FNP-C, a certified family nurse practitioner who joined Phelps Health Cardiology in May 2025. I care for adult cardiac patients in the Hospital. My collaborating physician is Stilianos Efstratiadis, MD, FACC, FSCAI. 

I was a third-year civil engineering student at Missouri University of Science and Technology when I realized that I wanted to pursue a career in nursing. It was a sudden decision, but I’ve never regretted it. I joined Phelps Health as an RN in 2014 and most recently worked at the Phelps Health Walk-In Clinic—Rolla.

When the opportunity arose, I shifted to cardiology because my family has a history of heart disease and I’ve lost close relatives to cardiac issues. I try to educate my patients about heart health. By guiding them to healthy lifestyle choices, I hope to help them prevent or avoid the serious heart problems that my own family has faced.

I’m naturally sociable and down-to-earth, and I try to establish strong relationships with my patients. I take the time to explain things fully and listen to their concerns so they feel comfortable talking with me.

I’m originally from St. James and now live in Rolla. Family is important to me, and when I’m not working, I love spending time with my wife, our four children and our dog, Winston. I’m also an avid outdoorsman, and enjoy almost any outdoor activity.
