Registered Respiratory Therapist
Registered Vascular diagnostic medical sonographer
I was born in Duncan, OK and raised in Kingfisher and Lawton. I have 4 siblings, one who is my identical twin. I graduated from Eisenhower High School and completed by Bachelor of Science degree in Chemistry from Cameron University. My medical career began at Comanche County Memorial Hospital in the Cardiopulmonary Department as a Respiratory Therapist in 1989 and pursued cardiovascular ultrasound in 1998.
From 2004-2009, I worked part-time as a sonographer with a local cardiologist. In 2009, I relocated and began working for Mercy Hospital in OKC as a Respiratory Therapist as well as assisting with (EBUS)Endobronchial Ultrasounds utilized for staging cancer.
I accepted an opportunity to provide diagnostic ultrasounds at Dr. Kadivar’s office in 2010 and I enjoy reading and listening to podcasts, audio books, and talk radio on my commute to Lawton. My wife, Janie, and I juggle the schedules and life’s journey with our 4 children, Jillian, Jason, Jessica, and Jennifer along with our dog, Lincoln, and cats.
