Our Staff

Thank you for trusting us with your oral health. We look forward to being a part of your lives!


Dr. Chris Costa

Dr. Costa received his dental degree from MUSC and completed his residency at the University of Florida. He received advanced training in a wide array of dental procedures including surgery, dental implants, TMJ disorders, cosmetics and occlusion. When he’s not restoring teeth, you are most likely to find Dr. Costa in the saltwater with a fishing rod, a surfboard, his wife and children at his side.


Dr. Tyler Williams

Dr. Williams received his dental degree from MUSC and subsequently completed a residency at the VA medical center in Charleston. There, he gained advanced training in a broad range of complex restorative treatments including implants, cosmetics and prosthetics, as well as TMJ disorders and chronic headache therapy. Outside the office, you will find Dr. Williams surfing, playing tennis, and biking…or in the kitchen creating something tasty.

Alison Muckenfuss

Office Manager

The first smiling face that you will see when you walk in our office is Alison. She is quick to welcome you into the practice and most afternoons her son, Micah, will be there with homework questions for anyone who is willing to help. Working hard to fund adventures with Micah, she handles the schedules, insurance filings, phone calls, and patient business to ensure your visits with us are seamless. When not at the office, she is Supermom!


Lauren Taylor

Dental Hygienist

Lauren moved to Charleston from the Mid-West where she grew up and earned a Bachelors of Science in Biology and graduated from Dental Hygiene School at University of Nebraska (She's a smarty pants!).  She is an exercise junkie and spends a lot of her time doing strenuous physical activities.  When she is not polishing teeth she is enjoying life in Charleston and spending time with her friends.  She claims her two closest friends are Ben and Jerry and that is why she works out so often : )


Juanita Magaña

Dental Assistant
A native of central California, Juanita moved to Charleston in 2011. She comes from a long line of hygienists and assistants and loves what she does. In addition to being a great assistant, she makes amazing mexican food! Outside the office she enjoys spending time with her friends and family, camping, and traveling. Juanita also somehow manages to know the exact words to almost every song we play in the office and will sing for you at no charge.


Cody Clark

Dental Assistant

Cody is one of our fabulous assistants and has been working in dentistry for over 5 years.  She grew up on James Island and is definitely a hometown girl.  She is the mother of a beautiful daughter and loves family activities at the beach and the park.  She loves that she can take advantage of the food scene in Charleston and considers herself a connoisseur of fine wine and sparkling water! 


Sarah Rodelsperger

Administrative Assisstant

Johns Island born and raised, Sarah is a Charleston girl through and through.  She left home only to attend Clemson University to receive a marketing degree, and is an avid Clemson sports fan.  Along with helping Alison at the front at Costa + Williams she manages Wingate Plantation, an event venue on Johns Island and plans local weddings.  When she is not working, which is rare, you can find her boating, shopping, and spending time with family and friends.
