4th Grade


Mrs. Seveska
Teaching remains my passion after 30 years, and I am fortunate to say that Oak Grove has played a huge part of that since 2005!  I am committed to educating the whole child and graduated in 1979 from Illinois State University with a Bachelor’s degree in Special Education.  I am certified to teach in five categories of special education and also earned my Bachelors in general education at that time.  I completed my master’s degree in 1981. I am still continuing to learn! My wonderful husband, Ron, is a retired school administrator!  We have three amazing children, Ryan, who works in the software industry and lives in Chicago, Katie, a 4th grade teacher in Buffalo Grove lives in Libertyville, and Jason, who works for Coca-Cola and lives in Grayslake. Our dog, Izzie, brings us joy!  I love to read, shop, travel and enjoy my daily dose of chocolate!

Mr. Henneberry
Mr. Henneberry joined the Oak Grove family in 2000 as a classroom aide and wrestling coach. Since then I have taught 6th grade Social Studies and currently teach 4th grade. My wife, a nurse at Condell Medical Center, and I reside in Libertyville. My education includes an Elementary certification as well as Junior High endorsements in English and Social Studies. When I am not in the classroom I can be found at practice. I coach 3 sports, football at LHS in the fall, wrestling at OGS in the winter, and lacrosse at LHS in the spring. My passion for education was born on the practice field and I believe co-curricular activities enhance the education experience of every student. I consider myself blessed to be teaching at Oak Grove and am grateful for the support I receive from the parents, administration and fellow professionals.

Mrs. Barmantje
I'm proud to say that this is my ninth year teaching at Oak Grove. I'm so grateful to be an Oak Grove Eagle! My education includes a Bachelor of Science degree in Behavioral Psychology from Western Michigan University and a Masters degree in Special Education from Roosevelt University. My husband, Kevin, and I have a two year old son named Hunter and a dog named Gus. On the weekends, we love spending time at our family home in Lake Geneva!
