Excel Health Institute is the best. Thanks to Mrs. Ellen the instructor and Mrs.Leferson the clinical instructor. I started my CNA class in April 2014 (4weeks long). Thanks to Mrs. Ellen and Mrs. Leferson I am a registered CNA. Mrs. Ellen is an awesome instructor. She's dedicated and encouraging to the students she have in her class. She was always ready for any question I had for her, and encourage us to. further our nursing career, and not just stop at being a CNA. If you looking to take a CNA class enroll at Excel Health Institute. Compared to all the other schools here in Manassas its the cheapest. So if your worried about pricing stop looking and call Mrs. Ellen at Excel Health Institute. Trust me you will not regret attending.
