Leadership

Pastors & Staff

Tiffaney Taylor

Family ministries director

I have been active in children's ministry for over 10 years. Most recently I was on staff at The Point Church where I was the Children's Ministry Coordinator for 6.5 years. It was during that time that I fell in love with kids ministry. I have been married to my husband Dave for 14 years and we have three boys, Reece (9), Chase (9), and Cole (2). I'm  excited about what is going on at Mosaic and serving as the Family Ministry Director.

Frederick Osei-Manu

Ministry intern

I am currently pursuing another post graduate degree at United Theological Seminary. I hold an MA in International Business and Management from the University of Bradford, UK and also BSc. Biological Science from the Kwame Nkrumah University of Science and Technology, Ghana.

I did bi-vocational work as a Banker and a Youth Pastor for a decade in Ghana. Also, I once served as a President of Independence Christian Fellowship and Prayer Secretary of the Inter-Halls Christian Fellowship.

I am married to Dr. (Mrs) Anita Akosua Osei-Manu and blessed with a son, Leroy Perez and a daughter, Graciela.

Cari Oehlenschlager

Director of discipleship

I am passionate about helping people intentionally grow in their relationship with Christ. This happens by finding their next steps along the discipleship pathway through personal connections, engagement, and using their God-given Spiritual Gifts to serve each other, the church, and our community.  

I have been with Mosaic Church since the very beginning. Also, I'm an adoptive mom to 3 kids - Brayden, Matthew, and Emily and have been a foster parent for 15 years. You can find me welcoming guests on Sunday mornings while my kids help serve behind the scenes. If I'm not serving the church, I'm likely on a ballfield or court cheering on one of her kids!

norm zent

facilities supervisor

I'm originally from western New York but I've lived in the Dayton area for the last fifteen years.  I work for Joshua Recovery Ministries and attend school part time.  My wife, Lisa, and I help with set up and tear down at Mosaic.  We live in Kettering with our two dogs, Brownie and Bianca.  Lisa and I love being a part of Mosaic and look forward to what God is doing through our dynamic church family.

Erica Simister

business manager

Hi, I am Erica Simister. I reside in Tipp City with my husband Jason. We have 4 daughters, Madison, Hannah, Josie and Emersyn and 3 dogs. I was raised in a small farm community and attended the University of Dayton. In the evenings and on the weekends, my family and I love to get together with friends and attend many local festivals and community events. I am so excited to be part of The Mosaic family!

Kareem powell

co-worship leader

My name is T. Kareem Powell and I am excited to throw myself, my skills, and my soul into Mosaic Church as your "other" worship leader. My goal - aside from the obvious - is to help everyone create a worship experience where they can find some piece of themselves inside the Mosaic.

I grew up in Miamisburg and at that time, the population of the city was overwhelmingly homogenous. My experience as an African-American was not something most of my friends and peers could relate to beyond an academic understanding. Though I resided in the same town, attended the same schools, and knew the same people, I was living in a "parallel universe" with challenges that were not encountered or even witnessed by my peers. I did not see my life reflected in my community. Many of those we are serving are having a similar - albeit not same - experience.

Navigating a career as a musician requires constant multi-tasking. While serving as minister of music at the St. Andrew (Avondale) and then St. Anthony (Madisonville) parish in Cincinnati, I was also accompanying musical theatre, performing in several jazz bands, teaching at Central State University, and serving on the executive board of the Dayton Musicians Association. After developments in my family life required me to cut back, a friend invited me to Ginghamsburg Church, where I have been regularly attending and serving as a pianist since 2012. Academically, I have a B.S. in Music Education from Florida A&M University and a Masters of Music Theory from Indiana University School of Music.
Bragging rights include: a duet with legendary pianist Ramsey Lewis, two appearances on the Grand Ole Opry with Jimmy Wayne, a jam with Americana artists Dom Flemons and Jim Lauderdale in a documentary about Italian bluegrass band La Terza Classe, my 2011 album "Reflections in Black and White" making one of writer/producer/director Reginald Hudlin's "Top Ten" music lists, a citation in a Mashable article about Patrick Stewart and ketchup, and dodging Pastor Roz's multiple attempts to sacrifice my beard.

callie picardo

preaching team

I’m thrilled to serve on the Mosaic Preaching Team.  Also, I  serve as Vice President of Development for United Theological Seminary.  I’m a finance person by trade, but also have a passion for seeing people grow and be transformed by the power of God’s Word.  I never thought she’d find myself in the pulpit, but a couple years ago, God clearly called me to be His mouthpiece and started opening the doors for me to preach His truth.  I married to Pastor Roz Picardo, and we have soon to be 3 daughters, Lily (3), Gabriella (1.5) and Hannah (June 2020)

mo kidd

co-worship leader

My name is Maurice Kidd.  I am an Akron, Ohio native and have lived in  the Dayton area for the past 15 years. I am a proud graduate of Central State University where I received my bachelor's degree in music education.  I'm also an alumni of Antioch University Midwest where I received my Masters of Education degree in special education.  I currently work in the Dayton Public School system as an Intervention Specialist working with children with learning disabilities.

 For a while I had been feeling God preparing me for something BIG. When I was approached with the opportunity to join the Mosaic team as a worship leader I knew that it was a God thing.  I'm truly humbled to be able to lead God's people in praise and in worship. I'm most excited about the way God is going to use His people from all different cultures and background to build His kingdom. To be apart of something so diverse is amazing. I can not wait to see just how God moves through Mosaic.

stephanie kellar

esl director

My name is Stephanie Kellar and I am the English as a Second Language Director for Mosaic Church. I am the daughter of Sara Gomez and granddaughter of Martha Lopez, founder of TCM (Tijuana Christian Mission).  We moved to TCM when I was 5 years old and my sisters and I were raised by my mom. I grew up with all the kids at the orphanage, dining together, going to school together, and attending church camps together. As I got older, I began helping with the missions teams that came to TCM. I helped with translating, guiding them around the city and  helped with their various community outreaches. Growing up at TCM shaped my life and is a big part of who I am today. I thankful that God put me on the path He did.
I look forward to meeting families with different cultural backgrounds and to get to know their stories. I am excited to bless anyone who walks through our doors. When I think of Mosaic, it feel like home.

wayne botkin

co-pastor

I’m Wayne Botkin and my wife Tricia and I live in Springboro.  We have five nieces who we enjoy supporting in their musical arts and variety of sports as well as with special weekend over-nighters and shopping excursions.  Yeah, they are amazing and we get to spoil them!  Tricia and I met at Ohio State and she finished up in Aeronautical Engineering and me in Business/Human Resource Management.

Why Mosaic?  Growing up, church was mostly an amazing experience.  In fact, I remember wondering, “why isn’t everybody in a church somewhere?”  I believe that when you follow Jesus, it is the most wild ride possible in life and most fulfilling at the same time.  Along the way, you’re going to meet an absolute cross section of people and especially “Church” then, should be a picture of heaven on earth.  My favorite scripture is when Jesus says, “I came that they may have life, and have it to the full.” ~ Book of John 10:10…  Church needs to be a place where uplifting conversations happen quite naturally, real connection with the creator God takes place and meaningful service to the world is like breathing.

One of the greatest experiences we’ve ever had was a trip to Seoul, South Korea just a few years back with a group of young adults from Christ Church.   We met up at a conference with 500 other young people from 49 different countries all there to learn together about how to best share the love and power of Jesus Christ with the world.  As each continent took a turn leading in worship in their own language and translating into English, we got a taste and a view of what Heaven will be like--different women and men from all over the world worshiping and praising God together.  The only difference in heaven will be that when we meet in small groups, no interpretation will be necessary!  

Tricia and I are so excited to be helping start-up Mosaic Church.
