Our Administrative team is made up of three people: the Head of School, the Brazilian Director, and the Academic Principal.


Mara Rangel (Brazilian Director)

Mara Rangel has been in the RIS for 7 years, and helping solve problems is her favorite part of her job. What drew her to work at RIS was that she believes God wants her here at RIS. In her free time, Mara likes to be with her family, and the coolest place she has been is Jerusalem. Her favorite food is pork.

Psalms 40:1 (NIV)

"I waited patiently for the Lord; he turned to me and heard my cry."


Michael R. Lindsay (Head of School)

Michael Lindsay has been with RIS for 8 years, and his favorite part of his job is walking through the preschool during nap time. Michael is from Phoenix, AZ, USA, where he previously worked in other high schools before coming to RIS. Michael has been to the top of the Burjh Kahlif in Dubai. He didn’t choose the RIS life, the RIS life chose him.

Philippians 3:13-14 (NIV)

“Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead. I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.”



Candice Spengler has been in the RIS family for 3 years. Her favorite food is Macaroni & cheese. Candice is from South Africa, and speaks English, Afrikaans, and is learning Portuguese. Before making RIS her home, she taught in South Africa and Taiwan. The reason she chose RIS was because of the international flavor of the school, a meeting place of the nations, and a safe environment for her children to grow up. Candice is grateful to be taking on a new role this year as Principal and anticipates a fantastic school year! In her free time she likes to read, run, and watch movies.

Zephaniah 3:17 (NIV)
“The Lord your God is with you, the Mighty Warrior who saves. He will take great delight in you; in his love he will no longer rebuke you, but will rejoice over you with singing.”
