Matthew Mastrorocco, DMD

Owner & Founder
University of Pittsburgh School of Dental Medicine

Dr. Mastrorocco hails from Derry, PA, outside of Pittsburgh. He earned his Bachelor of Arts from the University of Pittsburgh and has practiced dentistry in Hilton Head, SC since earning his DMD from the University of Pittsburgh School of Dental Medicine in 2000. Dr. Mastrorocco and his wife have three teenagers that were all born at Hilton Head Hospital.

“I can create or recreate a beautiful smile. I placed my first dental implant in 2007 and haven’t stopped learning all I can about them. An implant is such an incredibly efficient alternative to a bridge when a tooth cannot be saved.”

Jordan Haire, DMD

University of Louisville School of Dentistry

Dr. Haire was born and raised in Owensboro, KY and graduated from the University of Louisville with a Bachelor of Science in Cellular Biology and then the University of Louisville School of Dentistry. He moved to Hilton Head in 2020.  Dr. Haire believes that dentistry is about getting to know his patients and forming a bond with them. 

“I love meeting new people, hearing their stories about how we’ve ended up living in the same place, and just being able to provide excellent dental care to them and their families.”

Annette Callejo, DDS

The Ohio State University College of Dentistry

Dr. Annette Callejo was raised in Dayton, OH and attended Bowling Green State University, then The Ohio State University College of Dentistry. For Dr. Callejo, dentistry perfectly combines her passion for learning, her strong creative side, and her desire to build strong relationships with her patients.

“They inspire me to do my best for them, from even the smallest filling to a life-changing smile restoration, it’s all about the patient’s happiness for me.”

Dr. Callejo and her family have lived in the Lowcountry since 2018.

Robyn May, DMD

University of Louisville School of Dentistry

Dr. Robyn May was born in Cape Town, South Africa and moved to Savannah with her family as a child. After graduating with a degree in Cellular and Molecular Biology from Georgia Southern University, she attended the University of Louisville Dental School with our very own Dr. Haire!

“Dentistry can make patients feel vulnerable and even scared,” said Dr. May. “I love being able to reassure and guide them on their oral health journey.”

Dr. May was inspired to become a dentist after receiving resin-bonded veneers as a child, which transformed her self-confidence and enlightened her about the impact a dentist could have on her patients. She is excited by the advancements in technology that help make dentistry more predictable and long-lasting.
