Meet The Leaders
Arnaldo Concepcion, Senior Pastor
I moved from the exciting Bay area and relocated to the beautiful region of Sacramento. My passion and love for the Lord and His Word has been my cornerstone of why I had been called to be a pastor-teacher of Highlands Christian Church in Rocklin. What began as a driving love for God’s word, I was ordained as a Pastor and was called to teach and preach at Church of the Highlands in San Bruno, where I spent most of my walk. About 8 years ago, I had the desire of going back to school to further my education and to grow in my theology. In Spring 2017, I graduated with a Masters in Theology as well as having a Bachelor in Biblical Studies and Christian Counseling from Liberty University, VA.
Meet Pastor Arnaldo's family
Matt Tinetti, Pastor
I was brought up in a Christian home and spent most of my childhood in church. Not until 2005 had the Lord called me into full-time ministry. I began in ministry as the pastor/elder overseeing Children and Family Ministries, Special Events and Sports Fellowship at Church of the Highlands in San Bruno, CA. As you can see, I love children, sports and how it brings families together. I served there until 2013.
My Family and I relocated in June of 2013 from the San Francisco Bay Area to Roseville CA. My beautiful wife Nancy and I have been married for about 14 years and we are blessed with our awesome son Jordan and my beautiful daughter Madison.
Through prayer and faith I truly believe that God has called my family and I to continue ministering here with our new church family and the community. The Lord has placed a renewed passion in my heart to serve alongside the leadership of the elders and vision of my good friend Pastor Arnaldo at Highlands Christian Church of Rocklin.
My hope and prayer is that through my experience and calling I can be used by the church and ministry to fulfill the great commandment, teach the Bible and help people grow in the grace and knowledge of Jesus Christ.
Alex Catarroja, Pastor
My quest for truth began in February 2003. Not knowing the answer to the question, "What is going to happen to me when I die?", led me to a desire to seek God to find the answer. I prayed, "Lord show me the path to You, I just want to find You!" When you seek God in sincerity, He always answers. Thankfully, He led me to His one and only Son, Jesus Christ.
After recieving Christ, and growing in the grace and knowledge of His word, led to my conviction to proclaim His word through expository teaching.
My three passions in life are the Bible, family and sports. I'm happily married to my wife Liah and we have 4 children, Alynna, Alex Jr., Aaliyah and Alsaiah. Alynna is currently attending college, Alex Jr. is proudly serving our country in the Marine Corp., Aaliyah loves to sing and act, and Alsaiah has early aspirations to be a basketball player. My family is truly God's blessing manifested in my life.
I've had the privilege of serving with Pastor Arnaldo at Church of the Highlands in San Bruno, CA. God in His providence has led me to also serve along-side Pastor Arnaldo here at Highlands Christian Church, Rocklin. We are committed in helping you grow in the grace and knowledge of God and to come to a saving faith in Jesus Christ.
Robert E. Mitchell, Pastor
I have been married to my Proverbs 31 wife, Laura, since 1986. We have two children, Daniel and Benjamin (Benjamin, who is also serving as our worship leader). I was born and raised in the San Francisco Bay area and have lived in Roseville since 2015. So, of course as you may have guessed, I am a BIG sports fan of the San Francisco Giants! I'm a retired Police Sergeant from Pacifica P.D. (1982-2008). And it brings me joy to be able to continue serving God, His people and the community that we reside in, even after my retirement.
I have attended Church of The Highlands, San Bruno CA, for approx. 25 years and was blessed to be chosen as an Elder for the church in 2015 and now as an Elder for our church plant in Rocklin CA. I have served in the church's Jail Ministry Program (at San Francisco County Jail) since 2008. Since September 2015 (to the present) I've been blessed to have served at the Prison Ministry at Folsom State Prison. In 2016 I graduated from Western Seminary (Rocklin) as a Certified Church Chaplain. It has been amazing to see what the Lord has done in me and my family's life to draw us closer to him each and every day.
Bob Tinetti, Elder
My love for the Lord began at the age of 18 at the church that I first attended and served at, just a little under 20 years, Westlake Community Baptist Church in Daly City, CA. As God was guiding me, I was led to Church of the Highlands in San Bruno, CA. I continued there in my growth and in serving the body in various ministries. My passion to encourage other men allowed me to be very readily involved in our Men’s Leadership, Retreats and coordinating many impacting ministries for the men of the church.
I have been married to my lovely wife, Sandra for over 39 years. Through this, God blessed me with 3 wonderful children and 2 beautiful grandchildren. Of course coming from the Bay and lov-ing all sports, we are huge fans of the SF Giants, 49ers and the Golden State Warriors!
After serving at our home church for about 25 years, we relocated to Rocklin. We are excited to serve at the new church plant of Highlands Christian Church. My wife serves on the worship team and my desire is to continue to serve and develop young men to be soldiers of Christ. We look forward to serving this community.
Ben Mitchell, Elder/Worship Leader
It brings me such joy doing the two things that I love, the Lord and music. And it’s amazing that I have an opportunity to lead God’s people in worship. I spent most of my life in San Mateo CA, where I earned my Associates Degrees in Music and Electronic Music from the College of San Mateo. Soon thereafter, I graduated from UC Berkeley with my B.A in Music. As you can see, it is a passion of mine.
I married my beautiful and loving wife, Sharjah and we have a fun-loving puppy named, Mandi. I attended and served at Church of the Highlands in San Bruno throughout my life and at times alongside our Senior Pastor, Arnaldo. I am super excited to be involved in the new church plant in Rocklin, CA!!
