Welcome Ms. Gravelle!

First Grade, Room 4

It is my pleasure to introduce myself as Ms. Colleen Gravelle, one of the first grade teachers at Redwood Heights School. I taught as a co-teacher the past three years in both kindergarten and first grade. I  am enthusiastic to start my first year with my own classroom. I received my Bachelor of Arts in Elementary Education from Washington State University - GO COUGS! I grew up in Idaho and Eastern Washington state but moved down to California to be closer to family and I love it! I spend a lot of my free time with family and enjoying the outdoors. I love to play tennis, soccer, and go running. I am so excited to work with your children and watch them flourish as learners during the school year and into the future!


Welcome Mr. Kohles!

Fifth Grade, Room 28

My name is Sean Cameron Kohles. I am a proud Oakland native, a product of Oakland public schools (including RHS!). I earned my BA from Cal State University East Bay and my Master's in Education from University of San Francisco. I am super excited to be here. I've been an academic mentor for the past three years and am glad to finally be on board as a teacher. I am also the head cross country and track & field coach at Skyline High School. I have a passion for equity and discovering hidden talents. Everyone is good at something and I like to find out what it is. Everyone can succeed and I like to find out how to help them succeed.



Welcome Mr. Callis!

Special Education, Resource Specialist

Born in Salt Lake City, Utah, Mr. Paul Callis was raised with a great love and reverence for education.  Whether it be in the classroom, out in nature or learning the lessons of life from his amazing family.  At the age of 7 his family moved to Europe, spending a total of seven years there.  The first stop was in Germany where he learned how to play real "football" as well as master the German language.  After a year and a half his family then relocated to England where he learned the ins and outs of dry humor as well as how to be prim and proper.  After a well spent two and a half years in "Jolly Old" it was off to Switzerland. This is where Mr. Callis spent his Middle School years, at the American International School of Zurich. This was a great turning point, where the value of an amazing teacher was learned and he was introduced to skateboarding. Then in 1996 it was back to the states.


Upon graduating from high school he then attended the University of Utah, studying Psychology and Sociology, working in a lab for three semesters studying the awful effects of driving while on cell phones.  After earning his bachelor's degree he decided to join the Peace Corps and ended up being sent to the wonderful country of Haiti. Although short lived, due to being evacuated, it remains one of the most fantastic and educational experiences in his life. His love for the people, culture, music, and language remain very strong.


When it was time to move on, after a stint of substitute teaching, the decision was made that education was the route that would fulfill both the need to make a positive impact in the world and the desire to help open students' eyes to the beauty surrounding them.  He found his way to Oakland through the Oakland Teaching Fellows and in now in his ninth year teaching for OUSD.  


Mr. Callis has worked primarily working with students who have learning differences, helping to support and ensure that they are thriving academically and socially in the classroom.  He has had great success in assisting students in making gains in their reading ability and math aptitude.  He is a great advocate for his students, and encourages the use of art and creativity in all aspects of learning.  


He is very excited to join the Redwood Heights as the new Resource Specialist, knowing that his success will hinge upon his ability to be collaborative with the teachers, staff and families. He looks forward to working with you all.



Welcome Ms. Bank!

Special Education, Inclusion Program

Hi, I'm Sara Bank. I've worked in OUSD as a Special Educator for ten years. I've been taking time off, but am now happy to return to work part time as a Special Ed Teacher in a job share position with Monica Alcala here at Redwood Heights. I am really excited to be working with children and families again, and feel very fortunate to be here at Redwood Heights with so many excellent programs, enthusiastic and knowledgeable teachers, and an amazing school community.



Welcome Ms. Hines!

Garden Teacher

I am Annie Hines, Redwood Heights' new Field Science and Garden Coordinator! I'm a native of Oakland, self-proclaimed "Nature Nerd" and long time environmental educator. From 2012-2014, I served in the United States Peace Corps as a community environmental conservation Volunteer in Panama, teaching environmental science and helping to manage a sea turtle conservation project. There, with the help of some of my wonderful students and friends, I learned the importance of education in conservation.

Since returning to the United States in November of 2014, I have volunteered and worked all over the Bay Area to partner conservation and education before finding the garden at Redwood Heights. I am so excited to share my love of the outdoors with the RHS family.
