Andrew Lau


Lead Pastor (Exec Team)

As a learner, I love seeing what’s possible. Especially when I can help others steward their God-given abilities to live out God’s will. It’s exciting that our dream for a multi-ethnic church, where people use their God-given talents and strengths to serve the Kingdom, is now a reality!
You can often see me preaching and teaching at Cornerstone. I also help lead senior staff, partner with our board, work on strategic ministry, visioning, and I’m active in our counselling ministry.
I’ve been in ministry for 35+ years, received a Ph.D. in New Testament from the University of Aberdeen, and was an adjunct professor at Tyndale Theological Seminary. I live here in Markham with my wife, Libby, and our two children. I look forward to meeting you and working with you for God’s Kingdom.
Kevin White


Pastor of Youth Ministries

I’m passionate about seeing youth grow as Christians and helping them to be better members of our community. I’ve been here since 2007 and it’s been amazing to see many of our youth growing and being baptized. Just call me YourFriendlyNeighbourhoodYouthPastor.
I live in Markham where I serve as a Community Partner on the Greensborough Public School Parents Council and lead the Markham-Stouffville Youth network to support other youth pastors and leaders. I’m also a member of the Canadian Youth Network because I believe God will change the lives of youth across Canada.
I received my M.Div. in Youth and Family Ministries from Tyndale Theological Seminary. I’ve loved being a Youth Pastor since 2000 and hope its where God keeps me serving!
Bethany Nolson


Outreach Director

I love people! At a very young age God began to show me that there were people that lived differently than me in the world and that I could use the gifts and resources He gave me to love others. Over the years I have felt God’s heartbeat for justice through fundraising projects, community outreach, global service trips, and summer camp. I have developed a passion to educate, empower, and invite others to experience the joys of joining God’s fight against injustice in this world!
I love Cornerstone’s beautiful heart for our community! I love connecting with and empowering our church family to extend Jesus’s love to others and seeing people encounter God by getting out into the world, meeting people, and loving and serving our community. I am thrilled to be able to connect with our community to create powerful and caring outreach ministries to serve our neighbours. My role includes overseeing our local and global outreach, working with the amazing outreach teams at Cornerstone, and building our partnerships with organizations.
I am a big fan of crazy adventures, visiting new places and people, and long hikes with my dog. I have lived in Markham my whole life and joined the Cornerstone team in 2021.
Marie Walker


Facilities Manager

“This service that you perform is not only supplying the needs of the Lord’s people but is overflowing in many expressions of thanks to God.” – 2 Cor. 9:12
This passage resonates. Often unseen but vital to the operation, the Facility team’s objective to ensure a safe, clean and welcoming space in which to encounter Jesus, should return positive expressions from all who enter, to the glory of God.
With a passion for service excellence, I am excited to support the ministry programs of Cornerstone Church in this position, coordinating building, systems, and grounds maintenance as well as rental use.
Prior to joining Cornerstone Church, I managed facility operations for a charitable organization located in Stouffville.
My husband, Kirk and I, live in our Stouffville ‘empty nest’. Jesus is our cornerstone; we trace His faithful hand throughout our lives and continue to build our history with Him
Passions also include health & wellness, music and movement. When not ‘on the job’, I could be found leading a group fitness class at the leisure centre, volunteering at the local thrift shop, crafting at home or enjoying a forest walk with friends.
I’m excited to see how God will use my skills and talents to contribute to the ministries of Cornerstone Church.
Steve Shaw


Discipleship Pastor (Exec Team)

Over twenty-five years ago when I was a seminary student, Cornerstone had recently been planted. That’s when I first learned of the church’s intentionally intercultural vision, and it compelled me deeply. So I began as a pastoral intern at Cornerstone… and haven’t left since.
I have a heart for guiding people into real-time transformational encounters with Jesus, and help people learn how to put the teachings of Jesus into practice. I oversee Cornerstone’s discipleship process, including supervision of core ministry staff, and involvement in strategic planning. You’ll often see me preaching and teaching.
Intercultural ministry, theological reflection, contemplative spirituality and Latin American missions are my passions.
I hold a Doctor of Ministry degree in Leadership and Spiritual Formation from Trinity Western University, and am a trained spiritual director. I live in Markham with my wife Jan and our three children. I look forward to journeying with you as you walk with Jesus.
Kerri McIntosh


Director Children's Ministries

I’m a clown – literally. I LOVE having fun!
I believe there’s nothing better than teaching children right from scripture! I’m passionate about every child feeling, knowing and understanding that a GREAT BIG GOD loves them no matter what! And God values them enough to send His Son and wants each child to have a new life in Jesus.
My love for children’s ministry began when I attended Ontario Pioneer Camp as support staff at age 15 (I still serve as OPC’s summer program support). I further developed my skills by attending the Baptist Leadership Education Centre, and Centennial College’s ECE program.
My husband and biggest supporter, Todd, and I live here in Markham with our four great school-aged kids.
Phil Lam


Communications Director

Everybody has a story!
And I want to share how God is changing lives here at Cornerstone! I’m passionate about God’s mission and am a strong believer in the power of prayer – and as Communications Director, I want to share these passions with everyone.
Utilizing my strategic and achiever strengths, my role is to help set the direction and lead the strategic implementation of all of Cornerstone’s internal, external and digital communications. I want you to know everything that’s happening here at Cornerstone so you can be involved.
I live in Stouffville with my wife, Diana, and our two children Becky and Matt and volunteer helping the homeless and the working poor in the GTA.
Konstanza Lau


Administrative Assistant

As a member of the Administrative Staff at Cornerstone, I support the Ministerial Staff so that ministry can be executed smoothly and effectively. I enjoy working behind the scenes and am excited to be a part of the team.
Lisa Siu-Chong


Executive Director of Operations

I was introduced to Cornerstone back in 1998 and ever since then I have always been connected to the church. My husband and our three daughters moved away/back to the Caribbean for several years for work but throughout it all, I believe that God was truly preparing me for this next chapter of my life.
I have a passion for seeing people grow and develop and being their best according to God’s design, and it made sense that my professional background began in Human Resources. I progressed through various roles in the corporate world that included Marketing, Ecommerce, and Operations.
Over the years I began feeling a tug in my heart to continue making more and more space for Jesus by intentionally living out the mission of furthering God’s kingdom and putting more of my life’s work into an environment where this mission is not just a ‘by the way’ but it is the way.
The role of the Executive Director of Operations involves Operations Management, Financial management, Human resources management, Ministry strategy and planning, and Leadership development. I have been blessed that I can now use all the experience and skills that God provided me in a tangible way at Cornerstone. I am so excited and honoured to be a part of this team, and with an organization where there is a clear vision and mission to embrace the world and shape people together in God’s love.
Kristy Bhagat


Worship Director

I love music. I love the power of music to transport you to a moment in time, to express the inexpressible, to bestow urgent understanding and comfort when we need it most. Our Creator’s gift of music transcends all language and I have a passion for bringing people together with one voice, giving praise and glory to God.
As Worship Director, I am privileged to lead our Worship Ministry. Each week we make space for our church to encounter Christ through worship. Jesus is at the heart of what we do and our worship experience is reflective of that. In addition to the behind the scenes aspects of this role, you’ll often see me worship leading alongside our talented team. It is humbling that we get to partner with Christ in this way, and it is a privilege to lead our group of musicians in this collective desire to glorify His name and point people to Jesus.
When I’m not working on all things worship, you’ll find me with my family. Together we share a love of the arts, design and wellness. I am the proud mom of two girls and wife to my husband, Dirk. We live in Markham, but we also love traveling and chasing the heat!
Libby Lau


Food Director

I grew up surrounded by food in the family business, so it naturally became second nature to me. I recently retired as an early childhood centre chef where I worked for 17 years. My passion for creativity comes out in my menu planning and food preparation. As a maximizer,
I find it exciting to transform ordinary food into something unexpected. And I love cooking alongside others and providing cooking classes to help demystify the challenges of cooking.
My role includes overseeing Open Table Thursdays. Its where people who find joy in serving through the language of food intersect with others who are in need of refreshment, community, or a listening ear.
I’m married to Andrew, have two grown children and enjoy reading and writing in calligraphy.
Jann Aristorenas


Social Media Strategist

I have always loved anything to do with media, so growing up while seeing this world of social media evolve has allowed me to experience a lot of great things and meet new people. In my heart, I always felt called out to share God’s love and vision through various online platforms and am blessed to be able to work towards this goal.
Here at Cornerstone, I am excited to showcase the great community that God has developed. As part of the communications team, I hope to inspire and reach out to all kinds of people in order to bring them closer to God through this church, growing this community even more.
Jeremy Tao


Pastor of Group Life & Christian Ed

Church isn’t just Sunday, it’s Biblical Community! This is where life-change and mission happen best. We’re called to live in community.
I oversee the church’s various groups, classes and workshops. I love helping people connect into group life and hearing about their life transformation and how God gets into the midst of people doing life together! My role is to coach and train group leaders, so all our groups make the space for community and Jesus. I also help disciple people to discover their sense of identity in Jesus and experience God’s care and healing.
I started out as a Chartered Accountant and then became a pastor. I hold an M.Div. in Pastoral Ministry and Christian Education from Tyndale Theological Seminary. I live in Markham with my wife, Joanne, and our two daughters.
Mymy Leung


Welcome Director

I am passionate about family which makes it such a blessing to be part of the Cornerstone family. My role in the Welcome ministry allows me the opportunity to embrace old friends and newcomers alike, along with making space for all to feel the acceptance and belonging of Jesus.
I live in Markham with my husband Stephen along with our two teenage children. Aside from spending time with our extended families, I also have the chance to reflect God’s love in my professional life working with many diverse groups of people.
I can’t wait to meet you in-person and/or online and welcome you to God’s family!
Anna McCarroll


Office Manager

I want to get things done and help everything run smoothly! As Office Manager, my role includes providing financial information to Staff and Church Board, handling rental requests, overseeing I.T. needs and ensuring that we’re government compliant.
Before working at Cornerstone, I had worked and volunteered in various accounting roles. I grew up in downtown Toronto and graduated from York University.
I live in Markham with my husband, Peter, and our four children, Rachel, Rebecca (Becky), Ruth and Reuben. Our household represents three countries of origin as we’ve lived (and multiplied) in New Jersey, British Columbia and New Zealand.
Mary-Jane Dinsmore


Administrative Assistant

I love Jesus and have a passion for all of His people, especially for everyone who comes through Cornerstone Centre’s doors, or calls us on the phone. If you have a request, I’ll do my best to help.
As part of my role, I provide administrative support for our Executive Team and up-to-date communication for our Cornerstone family through weekly e-news and worship folders.
