Lulie Negreira

Business & Finance

At the age of 21, I began my non-profit career as a social worker for the elderly living in public housing. I have always loved helping people of all kinds be it the elderly, physically challenged, or children. As my career for helping the community evolved (meaning I got older), I moved into administrative roles and now have more than 25 years of finance and grant administration experience including being responsible for managing budgets of more than $5M in grant awards.

As the Center has evolved, so has my role. I began as a part time Finance Manager to my current role as Co-Executive Director. I look forward to continuing to working closely with the C4SC staff (also known as my second family) and our valued members while helping to create a long and sustainable future for C4SC for many years to come.

Personal Facts about Me:
I was born and raised in Miami, Florida and I am a proud Cuban-American. I have a passion for photography and love a good movie on the weekends but most of all, I enjoy spending time with my daughter and my five little fur-babies. I love jet skiing and being outdoors (when it’s not too hot).

Operations & Membership

At the Center for Social Change, I love having a wide-angle view of the social impact community, supporting a broad range of causes and connecting our members to each other and the community. I enjoy fostering a fun and friendly environment where members can benefit from shared resources. I believe everyone has talents and passions that are best expressed when they are connected to aligned people and opportunities.


I strive to create an ever-more inclusive and welcoming environment, as well as energize those who envision a better Miami (and world). I’ve witnessed a transformation at the Center and of myself since I joined the team in 2014 and I am excited to continue our evolution. Because of our culture and working with a variety of organizations, there is no lack of learning opportunities at C4SC!


My background:

At the University of Miami I studied Human & Social Development with a focus on Community & Program Development. Social entrepreneurship seemed like the perfect marriage of my entrepreneurial instincts and my desire to help others. I was grateful to complete my practicum with a local organization called Empowered Youth assisting with their social enterprise. In my search for a practicum location, I found C4SC and began working here shortly after graduation from UM. At UM, I was involved with Random Acts of Kindness Club and started a special interest housing floor called Harmony, where we focused on yoga and a healthy lifestyle.


I started my “career” at 8 years old as a pet-sitter, house-sitter, baby-sitter, newspaper deliverer and soap maker. I have always enjoyed spending time with people with special needs and I worked for several individuals with Autism and Down Syndrome during my summers. Now I spend my free time with senior citizens at Bay Oaks Retirement Residence. I keep my board games and beach supplies in my car so I am always ready for an adventure!

Lucinda Kerschensteiner, MBA

Senior Strategic Advisor

After four years in the Executive Director role at the Center, I am now contributing to the strategic growth and sustainability of the organization as an advisor and working closely with the team. Known for my organizational, coaching and planning skills (I think the team would agree!), I have helped nonprofits and businesses for over 24 years with individual, team and strategic development. I love spreadsheets, 2×2 matrices and edit the heck out of any document that is sent my way.

Prior to the Center, I worked for a nonprofit consulting firm in Denver, a workforce development agency, a career outplacement company, an arts incubator program and ran my own consulting/coaching practice. As a “9” or a Peacemaker on the Enneagram, I have coached and facilitated hundreds of individuals and groups in transition around the country.

I live in Fort Collins, Colorado with my husband and out of a desire to spend more time with my family in Miami, I connected with the Center several years ago and have worked remotely long before Zoom was the norm!

I also contribute to Educate Tomorrow, a Miami-based nonprofit that supports vulnerable youth to achieve higher education, and I founded Uhambo USA, a nonprofit that supports a social enterprise in Cape Town, South Africa that creates inclusivity for children with disabilities.

Completing my MBA from Colorado State University’s innovative Global Social and Sustainable Enterprise program was a highlight and sparked my interest for social entrepreneurship. A long time member, I now sit on the Board of Directors for the Rotary Club of Fort Collins and contribute to our local community service and international grants committees.

Some fun facts:
• I went to all-girls’ school in Ohio (all 12 years!) followed by an all-women’s college in Pennsylvania.
• I am 6’ tall and yes, I played basketball, but of all the sports I played, my real love was lacrosse.
• Today I enjoy running on the trails in the Rockies and English style horseback riding and jumping.

Lupe Joy

Membership and Community Program Coordinator

I am the Community Project Organizer here at the center and I feel inspired by the amazing people around me that are changing the world. They help me remain hopeful for the future and I am energized and encouraged every day at the Center by their commitment and perseverance!

I’m a nature lover, I like the beach and the sun, dancing, kids and working with young people. I love getting into trouble and being challenged even though it terrifies me to fail. New concepts and ideas motivate my imagination and keep me feeling young.

I have worked in different fields all related to service in one way or the other, mostly with children and adults with developmental disabilities but also with the elderly in Nursing Home settings.

Connecting through interaction with young people, the staff at C4SC, I feel socially and culturally motivated to be an advocate for peace and understanding between various generations.

Wellness Director

Lucky me, I get to be the Wellness Director at C4SC! My passion lies in exploring what keeps people vibrant, healthy and active. As a certified Yoga instructor and Meditation Specialist for the past 13 years, I’m still in discovery mode with myself and the world around me. I’m a strong believer that imagination, meditation, yoga and movement, can profoundly change anyone’s life.

I have served as Professor in Yoga studies at Pratt Institute in NYC and some of my clients include BET Networks, The Rush Philanthropic Arts Foundation and We Work. Creating a wellness culture in a workplace setting makes for happier and healthier people in the world, and its been my pleasure to support professionals, small businesses and the greater community. If I’m not traveling, dancing, going to the beach or connecting with people I love on the regular, I turn into a monster :-I
