Board of Trustees

The Board of Trustees of Temple Sinai is made up of a cross section of the Congregation and is nominated to serve terms according to the by-laws.  Usually, the Board is comprised of approximately 20-25 members, and includes the auxiliaries of the Temple (Brotherhood, Sisterhood, and Temple Sinai Youth Group – TSYG).

Although its primary duty is one of a fiduciary nature, to oversee the financial operations of the Temple, it has far reaching responsibility to provide diversified programming through its multitude of committees.  Additionally, the Board of Trustees oversees the general governance of the Temple. In addition to the Board, the Executive Committee (not to be confused with an “Executive Board”) is comprised of the Officers of the Board – President, Vice-Presidents, Treasurer and Secretary.  Their duty is to review matters of general interest and concern to the Board, and then make recommendations.  The Executive Committee has no authority to make policy unilaterally, nor modify the approved budget.  Requests that fall outside the approved budget are reviewed by the Committee and, again, a recommendation is made to the Board. The Board may elect to accept or reject any recommendation based upon its merits.The Board of Trustees meets monthly, as does the Executive Committee.

Any member of the Congregation is welcome to attend a Board meeting.  Dates and times are posted in the monthly Kesher calendar, Snippets and on the Temple Sinai website.

Thank you for the opportunity to serve again on the Board of Trustees.  I've enjoyed getting to know our Sinai kids and families through Youth Group committees, Religious School, Music Programs and more.  We are a native Denver family and appreciate the strength of community and faith we have felt at Sinai since joining in 2002.  I have been a realtor for over 20 years and enjoy helping clients through the process.  Along with my husband Doug and daughter Tess (14) and Bree (12), I look forward to meeting you.

Jeff Lavenhar

One of the great blessings of my life is my involvement of over 25 years with Temple Sinai.  The lives of my daughter, 26 and son, 30 were positively shaped as youngsters, from preschool and through b’nai mitzvah, by the extremely dedicated clergy and staff of our Temple.  The loss of my parents was softened through the attentive involvement of clergy, staff and Temple members.   My family’s association with Temple has contributed greatly to our lives and provided an immense measure of joy, spirituality and support.

I have been involved in the transactional side of the energy business throughout my career.  During this time I took 14 years as the founder and director of an adoption agency, together with my former wife Laurie.  Participating in the adoption of almost 400 children has been another blessing of my life, and I consider it to be the most important and meaningful work that I have done.  The agency benefited from the guidance and support of two Temple Sinai members who sat on our board.

Another blessing through Temple was my trip to Israel in 2015 led by Rabbis Rick and Susan Rheins.  This was one of the most stirring experiences of my life.  It is difficult to describe the incredible contributions made by our Rabbis, who constantly enhanced the meaning of our experience while expressing an infectious love for Israel.   

I enjoy participating in the Temple Sinai choir.  My involvement greatly enhances my worship experience, has created new connections, and is just plain fun!

I hope to give back to Temple through my involvement on the Board of Trustees.  I am an advocate of our Listening Campaign and urge our membership to deepen your involvement in Temple.  The results will be more than you could imagine, and will benefit and enrich your life.

Kathy Zeiger

13 years ago my husband and I found a Jewish "family" home at Temple Sinai.  We were blessed to be one of Rabbi Zwerin's last weddings.  I have had the honor of being called to the bimah for my Bat Mitzvah and Confirmation.  My husband and I have served as Purim carnival co-chairs.  I also served on the Sisterhood Executive Board from 2007-2008.  We celebrated the births of our daughter, Eliana and son, Mateo, with their Simchat Bat and Brit Milah.  Eliana and Mateo are proud graduates from Temple Sinai Preschool and are active in Religious School as well.  During my children's time in preschool and religious school, I have volunteered on several committees such as the Mom's Group, the Shabbat Initiative, 1st grade Parent Liaison and as the Social Action Committee co-chair.  For the past year I have also worked with the Temple Sinai Preschool Building Jewish Early Childhood Education Team to increase enrollment, better engage Jewish families, and build stronger connections to the Jewish community.

As a board member, I feel like I would be working towards completing the "work" of the congregation.  L'dor va'dor is how we continue to build and grow our community.  This tenet of Judaism is one I hold fast to and the one I would like to bring to the Temple Sinai board.  I want to continue to build upon the connections and relationships we have with one another and extend them to the larger congregation.

Lane Feingold,

Vice President

I am a proud Colorado Native who grew up in Aurora and attended Rodef Shalom throughout my childhood. Throughout college at CU-Boulder, I worked as a teacher and Bar/Bat Mitzvah tutor at Congregation Har Hashem. While teaching 7th grade at Har Hashem, I met my soon-to-be wife Jennifer. I also enjoyed tutoring for Bar and Bat Mitzvah at Temple Sinai for a few years in the mid-2000s as well as co-led the Shevet Achim program that ran for a few years beginning in 2011. My family has been members at Temple Sinai since 2006.  I am honored to be on the Board of Trustees and to serve on the board because of my love for the Sinai community and my want to help move Temple Sinai into the future as the model of a successful synagogue evolves.While not spending time at Temple Sinai, I work at Motorola Solutions selling public safety systems and solutions to State and Local Government agencies in Colorado. I also enjoy playing handball, spending time with my wife and children, Mira (11) and Benjamin (9), as well as following Denver pro sports. 



Vicki Goldman,


It has been a joy and privilege to be a member of Temple Sinai my entire life.   As a child I attended religious school and services at the First Plymouth Church in front of the cross that we said was a “T” for Temple.   When I became a teenager I had the honor of serving as president of Temple Youth Group.   Like many long time congregants, I attended High Holy Day services in the building on Dartmouth where we were able to see the sunlight streaming through the cracks in the walls.   When David and I were married by Rabbi Zwerin, the ceremony had to be held at the Hebrew Educational Alliance because the sanctuary on Glencoe was still under construction.  Our children Corey and Marissa have also had the privilege to grow up at Temple Sinai, and become Bnei Mitzvah and confirmands.  As you can see, Temple Sinai and I have moved through life together.

My experiences have made volunteering at Temple Sinai a natural and important part of my life.  When my kids were in religious school I was involved in the classrooms and made latkas and hamentashen.  My family and I volunteered in the kitchen for the Purim carnival for a number of years.  I sat on the religious school committee and worked on the Chanukah dinners. 

Most recently I worked with the building committee to obtain financing for the construction of our new learning center and chapel.   Over the past five years I have been involved in the Sinai Simchas and the annual events.   In addition to serving on the board, I am a member of the finance committee.

Temple Sinai, the community, clergy and staff have given so much to me though out my life, and my hope is that I can help to insure that Temple Sinai is there for many years to come.
