Haze Dennis

You never know what God has in store for you. Haze was born and raised in St. Louis Missouri. The entire time growing up, Haze wanted to be a dentist, and aligned his college preparation and application efforts for such. Haze also worked at an early age on the Mississippi River Front in his uncle's snack shop, as well as working the ubiquitous fast food gig during his senior year. Little did he know that these early jobs would lay the foundation for a career, not in dentistry, but in the foodservice industry and then in hospitality education. An unexpected pivot during his senior year in HS landed Haze at the United States Air Force Academy instead of dental school. Had he graduated from the Academy, Haze would have been commissioned as 2nd Lieutenant in the Air Force, but that was not to be either. Upon returning home from the Academy, Haze fell back on the experience from his youthful food service jobs, and attended St. Louis Community College for hospitality management. Completing his AS degree, Haze transferred to UNLV where he earned his BS. Through stints in correctional food service, Stanford University Dining Service and Athletics and Concession services, Haze wound up in the Bay Area, where his career in hospitality education, at Mission College, began. Baptized at an early age, God has been a constant source of strength and perseverance throughout Haze's life. Haze has finally accepted the call to formally serve, as a board member.

Soraya Muffenbier

I was baptized at the age of 17. My parents were Christians and I grew up in the church with my parents in Indonesia. I have been involved in small bible studies and worship teams in the church my whole life. I served at the New Life church of Batam city in Indonesia and I was married in that church. My husband and I moved to California in 2018.
I am currently working as an RV park manager and plan on attending medical school full-time very soon.
I came to Santa Clara First Baptist Church in January 2019. We are active in our community, helping others in their life and faith. I am part of the worship team and it has been a source of joy for me.
I am also part of the YoPro life group where I can find a positive vibe among the people. I have developed many good relationships at SCFBC, and it is a big blessing in my life. My dad always said, it is good to do things that you are passionate about, but it is more important to fulfill the purpose of your life. To be an active member of this church and serve God is something I can do. I believe, hopefully, this is God's purpose in my life: to become a blessing to others.
