JTown Governing Board
It takes a village to run JTown!

Debra Reinhard, Secretary

I grew up in the Suburbs outside of Boston. I graduated from Simmons College with a BS in Physical Therapy. I relocated to Denver in 1995 and have been loving it ever since.  Becoming a single mom of three children in 2005, I decided a career change was necessary for my lifestyle. 

I have been a full-time realtor since 2006. Getting into the business at the start of the crisis reinforced my hard work ethic and follow through. Raising my children on my own also forced me to prioritize, multi-task, and manage crises big and small.

I have volunteered for various organizations over my 23+ years in Denver. Some formal such as being a board member at Temple Sinai and Belleview Elementary, some informal such as volunteering at JFS or the Pet Pantry. Through it all, I was looking for something to call to me.

Since becoming involved at JTown, I feel like I am home. I have met a group of like-minded individuals. Whether it is a movie night with the ladies, services, or a weekend of service at Project Our Town, I have the passion and desire to be involved.

Lisa Zolle

I was born and raised in Southern California, earned a BA in marine biology at California State University, Fullerton. I taught Advanced Biology and research classes at Heritage High School for 17 years. Recently retired, I volunteer about once a week as a docent at the Denver Zoo. I bowl, golf, love the theater, trivia (Jeopardy), travel, animals, baseball, and outdoor activities. 
Judaism has always been an important part of my life. I grew up going to a traditional synagogue until high school when my family joined a Jewish organization very similar to JTown. It was geared to all ages with many options for attending different programming. I also was part of a performing folk dance troupe, which was a terrific experience. During summers I was a counselor at Brandeis Bardin Institute in California and was a Bat Mitzvah there at 16 after having taught myself enough Hebrew to read my portion. Leaving a “synagogue” setting for awhile but still celebrating the important Jewish events with my family, we joined Temple Beth Shalom after moving to Colorado, leaving after my kids went through their Bar and Bat Mitzvah. Now years later, I discovered JTown and feel at home. It is hard to put into words but the welcoming and warmth of its members, social time along with services, and extra social and intellectual programming, have all made an impact on my life and my Judaic faith. 
I am very excited to be part of this community on a planning level and I hope I can make a large contribution to something that is important to me.
