Dr. Rafael Siqueira

Dr. Rafael Siqueira is originally from Recife, a beautiful town on the coast of Brazil. He attended the University of Pernambuco in Brazil and graduated from dental school in 2010. 

He then went on to complete a Masters of Implantology which is similar to a US residency program. After completing that, he joined a PhD program at the Federal University of Pernambuco which sent him to the University of Michigan to do research for his master’s thesis. Once he completed his PhD, he headed back to Michigan School of Dentistry for a 3-year residency in Periodontics. During his time in school and residency, he was able to publish over 30 scientific articles in international peer reviewed journals and write five book chapters. This resulted in a few awards over the years. 

Dr. Siqueira’s interest in dentistry started to develop very early in his life by watching his parents who are both dentists. He observed his father teaching students and treating both students and patients with compassionate care. He witnessed a few instances where patients were moved to tears by the results of his father’s care and students whose lives were so strongly impacted by the mentorship his father provided on their path to become a Periodontist or Implantologist. Dr. Siqueira soon realized he wanted to have that same positive impact by being a dentist, educator and researcher.  

Dr. Siqueira describes himself as not only family-oriented and very sociable, but also easy-going and calm. He loves being with friends, having a good time and sharing great food. He is typically very optimistic. He is married to Renata, a lawyer, who just recently gave birth to their first child, Thomas. They do not currently have any pets but hope to add a dog to their family in the near future. Dr. Siqueira is a big sports fan, food lover and loves to travel. His hobbies include playing tennis, watching sports, exploring new restaurants, travelling and meeting new people, and learning new languages. A fun fact about Dr. Siqueira is that he speaks his native language, Portuguese, as well as English, Italian, and can communicate quite well in Spanish. He is currently taking a Spanish course to improve his fluency.
