My verse this year is 1 Corinthians 16:14, "Let all that you do be done in love."

I am so grateful to be serving at GCA for my second year. I love interacting with the students and being a part of a community with the families and staff. I am looking forward to another year of growth and seeing what the Lord has in store for our school.

​I love singing/music of all sorts, adventuring with my dog, spending quality time with friends/family, and being outside as much as possible.

This is my second year working at GCA, and I am thrilled for this year and the
future at GCA! The Holy Spirit is at work here and God is always so generous and faithful. It’s so amazing to see how God is answering our prayers. My 4 children have
attended GCA for 3 years, and my older kids are especially excited for the
changes in middle school & high school. This is an amazing time to be part of the
GCA family and I’m so blessed to work here!
​
My verse for this year is Philippians 4:8, “Finally, brothers, whatever is true,
whatever is honorable, whatever is just, whatever is pure, whatever is lovely,
whatever is commendable, if there is any excellence, if there is anything worthy of praise, thing about these things.

My verse for this year is Joshua 1:9 "I hereby command you: Be strong and courageous; do not be frightened or dismayed, for the LORD your God is with you wherever you go."

I enjoy using my bilingual skills at GCA to help families, children and staff communicate with each other. I enjoy encouraging students to remember of who they are in Christ daily.

In my free time I enjoy camping with my husband, two kids and dog. We enjoy playing board games, video games, swimming and music. We have been members of Discover Church since 2015. We are actively involved in various areas of ministry such as Youth, Safety and Security and Missions.

​Esther 4:14 says, "And who knows but that you have come to your royal position for such a time as this? For if you remain silent at this time, relief and deliverance for the Jews will arise from another place, but you and your father's family will perish".

I currently serve at Milwaukee House of Prayer, Truths Moment’s Ministry, Way of Righteousness Ministry, the Ridge Community Church, Worship Burns, Worship Leading, and Inner Healing and Deliverance Ministry.

I am so excited to see a revival of the Holy Spirit and I am expecting miracles, healing, and breakthroughs for every student and staff member here. We are all here for such a time as this.

I have been married for 17 years, we have two beautiful daughters, a little chin-pin, a bird, hamster, and 2 frogs. I love kayaking on rivers, singing, traveling, deep conversations, antique things, and revival adventures.
I am so excited and blessed to be here!

This is currently my 23rd year at GCA. I endeavor to instill in each child a love of learning, a love for God’s word and its principles, and to help them learn how to apply God’s work in their daily lives. My verse for the year is Psalm 90:17 “Let the favor of the Lord our God be upon us and establish the work of our hands.”

I am one of 11 children. I love to do crafts, baking, watching old movies, and spending time in nature. I attend Bridge Church in Waukesha, where I have attended since 1981. I am involved in the Meal Wagon.

My favorite verse is Proverbs 19:21 "Many are the plans in a person's heart, but it is the Lord's purpose that prevails.”
​
I attend Passion Church. I am excited about working at GCA because I love working with children and being able to share Jesus with them in everything we do. My philosophy is to provide a safe environment and to be able to help each child grow. I just celebrated by 34th wedding anniversary. I love spending time with my children and grandchildren.

I have been the aide in the kindergarten class for all of my three years here. Since the very beginning I have enjoyed every bit of my time at GCA. I am very thankful to God for guiding me in the direction to serve the children of Grace. This year my verse to guide me through the school year is-  Matthew 5:16 “Let your light shine before others, so that they may see your good works and glorify your Father in heaven.”

I have been a member for 39 years at Jackson Park Lutheran Church - baptized and confirmed. I am a very friendly person, always sharing my smile with others to brighten their day,  always leaving negative behind me, and praying through to see the positive.
