Meet Our Team

Siobhan Thomas RDH


Graduating from Howard University's College of Dentistry, I have helped clients maintain bright smiles over 20 plus years  as one of the top dental hygienist in the DMV area.  My bubbly personality and attention to detail has allowed me to sustain great relationships with patients and dental offices. 

As a true creative, my entrepreneurial spirit blossomed in many ways throughout the years. First, as a makeup artist and esthetician and then as co-owner of Jace Anthony hair salon.  My combined experience in both the dentistry and beauty industries has prepared me for a new season to serve my clients....THE SLATE LLC. 

I take pride in ensuring that my clients have beautiful smiles which makes them feel healthy on the inside and outside.  This philosophy resonates in my own smile that I make sure to share with everyone I meet. 

Dr. Bridgette Rhodes


After 26 years of "drilling and filling" in private practice,  and 5 years of teaching as an assistant professor at Howard University's College of Dentistry, I arrived at a point in my career where I wanted to offer my patients what I know that they wanted....HEALTHY, WHITE smiles at a reasonable cost.  I collaborated with Siobhan, a registered dental hygienist of 22 years and developed a business model that would give our patients what they wanted.  By keeping our overhead low, we are able to pass the savings on to our clients.  I used my history of teaching and knowledge of dental materials to research whitening products for their efficacy and safety and derived a system that would give our clients WHITE teeth and help them maintain with REGULAR maintenance.  Now, our clients can have the WHITE smiles that they always wanted and still enjoy their coffee, tea and red wine.  A HAPPY WHITE smile is priceless.
