Catherine Lautenbacher


Program Director for 
Leadership Sandy Springs

Where she gives: Dunwoody Nature Center, Community Assistance Center, Rep. Karen Handel’s Service Academy Selection Committee

One thing to make the world a better place:  Instill in each of us the value of community.

Catherine, one of Dunwoody’s most outstanding champions. The president-elect for the board at the Dunwoody Nature Center knows how to lead by example, and giving is mostly a family affair involving her husband Conrad Lautenbacher, their daughter in college, and son at Dunwoody High School.  Incredibly humble, she prefers all the attention be on the non-profits rather than herself, but it is people like her that inspire the rest of us to do what we can to make our communities the best they can be!  When not being a pillar of service, Catherine enjoys playing tennis with her Mill Glen neighbors.  

Brian Seitz


Real Estate Investor / Finance

Where he gives: 2019 JCC Maccabi Games in Atlanta, The Epstein School

One thing to make the world a 
better place:  I’d end all the current hatred and anger in our society.

It’s not hard to wonder why this former high school teacher and coach at Roswell High School and Northview High School is so likeable. Brian is incredibly empathetic and has a huge heart.  Volunteering and giving are just a way of life for him, and he is honored to act as co-chair for the JCC Maccabi Games hosted in Atlanta, that features Olympic-style sporting competitions.It is the largest annual Jewish youth event in the world.  These athletes also participate in community service opportunities in addition to excelling at sports. When Brian is not working or volunteering, it’s clear his family comes first.

Julia Stahlman


International Baccalaureate 
Student and Artist

Where she gives: Art for Art, ACTWATER.ORG, Riverwood Recycling & Environmental Club, Academic Tutor, National Honor Society

One thing to make the world a better place:  I would strive to make a difference by creating meaningful connections between people and groups in developed and underdeveloped communities around the world.

It’s not every day that you meet a high school student who has founded not one, but TWO charities!  Enter the inspirational and kind hearted Julia.  Focusing on finding new ways for people to communicate on a global scale, she is the founder of Art For Art, a non-profit that partners locally and internationally to hold art exhibits in the U.S. that showcase artwork by children from underserved communities in Africa providing financial support for their educational programs.  Her second charity is web-based, addressing the health threat affecting the drinking water of millions of Americans.  Julia is a Junior at Riverwood International Charter School. When not giving of her time and talents, or at school, she has played competitive soccer for the past ten years and has studied four languages.

Mr. Tom’s Heart

Where he gives: Mr. Tom’s Heart

One thing to make the world a 
better place: To cure cancer!

Once in a while, you meet someone that just immediately wraps you in the warmth of their heart, and that person is Tom Umstead.  The founder of Mr. Tom’s Heart says, “sick children and their families are my passion,” and his commitment and leadership is substantial. The nonprofit human services organization that brings food, clothing, toys and crafts, and various sundries to Ronald McDonald Charities, Children’s Healthcare of Atlanta, Adult Day Care, Calvary Children’s Home and senior centers is such a success thanks to 100-plus volunteers who fuel Tom’s army.

Maqueline Weiss

Sandy Springs 

Senior at Mount Vernon 
Presbyterian School

Where she gives:  Juvenile Diabetes Research Foundation, Camp Kudzu, CHOA, MV Ambassador Prefect, MV Innovation Diploma Executive Team Member, MV National Honors Society Secretary

One thing to make the world a better place: Ideally, I would love to see a cure for Type 1 Diabetes in my lifetime, but knowing that others are afflicted with other diseases, I would like to see increased funding and medical research for various diseases; therefore, benefitting humanity at large.

Impressive doesn’t begin to describe this self-proclaimed girly-girl senior at Mount Vernon Presbyterian School.  Having Type 1 Diabetes, she really doesn’t let anything stop her.  And although she may be wearing the most fashionable heels in the room, her real power comes from the ambassador and lobbying work she does on behalf of Juvenile Diabetes Research Foundation.  She’s raised over $100,000 and won an Honorable Mention for her documentary about Type 1 Diabetes for CSPAN.  Maqueline was chosen as an Educational Leader 21 student panelist and presenter in the topic of 21st century learning, one of the five students around the nation chosen to cover the power that students have in their community and how much real world work they can do.  She loves to be a dare devil on her Sea-Doo on Lake Lanier or cook with her family of “real food foodies”.  

Karla Worley


VP of Business Development, Regulatory Datacorp (RDC)

Where she gives:  Partnership Against Domestic Violence (, Dunwoody Nature Center, Sandy Springs Christian Church

One thing to make the world a better place:  If we all committed to doing what we could to help those that are disadvantaged.

Spend one minute with Karla and it’s clear she is a woman who is committed.  Committed to her family including three daughters, to her industry, to her community, and most importantly –  committed to helping women and children who are disadvantaged.  Although her list of volunteer organizations is long, the most near and dear to her is Partnership Against Domestic Violence, where she serves as a board member and as a chair for their annual gala raising more than $700,000 over the last two years.  The funds raised will raise awareness to fight the crime of intimate partner violence and empower its survivors through support and education. When not giving her all to everybody and everything, she loves to compete in athletic events pushing herself – this past year she completed her first Olympic  Chattanooga Waterfront Triathlon in June, and placed 8th in her age bracket!
