"I have been with K&A since passing my RD exam in August of 2022. I have been working mostly inpatient for the past 1.5 years. Now, I am doing a range of things such as working with D.D.S.D clients and helping with the internship. I enjoy the flexibility and range of positions that K&A has to offer, and I’m enjoying learning new things! "
