    I started working with Dr. Gaston at Veterinary Medical Center in 1996 as a part time receptionist. I loved working with animals and clients so much I quit my day job and stared working full time with Dr. Gaston.

I started managing all of our online marketing, client communication, reviews, website, and social media. I also manage our in house networks for both clinics.  

    I was born in Atlanta then moved to St. Croix, V.I.  when I was 3. I've lived in South Florida, New Jersey, and New York.
