Hi, I’m Berthony. I began my medical journey as an RN in 2003. I’ve worked in various capacities in and out of the hospital setting to include critical care and emergency department. I’ve completed undergraduate work in pre-medicine, and continued on to becoming a board certified Family Nurse Practitioner (FNP-C). On May 2017, I obtained my specialty certification as a nationally registered medical examiner for CDL drivers. I also have a few years of CDL driving experience both local and “over the road.” I am a proud veteran of the United States Army. Mark 10:43 Whoever wishes to be great among you must be your servant. We are available to serve you.

I know what it is like to be a CDL driver with all of its demands and requirements. We greatly appreciate your business relationship and look forward to greater things ahead.
