About Us

Human Development Associates, Inc. (HDA)

We're a nonprofit 501(c)(3) educational and charitable organization.

HDA was founded in 1974 by psychotherapist and pastoral counselor Marjorie L. Felder (1921-2011), to facilitate positive human development. Over the years, HDA staff have provided individual sessions, personal growth groups, and consultation to other nonprofit organizations. HDA has developed training programs for interns and volunteers for working with individuals and groups on a professional level.

HDA projects have included a meditation garden, retreat center and more recently, art programs. Our aim continues to be to provide income-scaled programs that enhance human potential. Our aim and core values stay steady. Our programs continue to develop. Stay tuned!

What's Next?

Articles on facilitating positive human development

In addition to recruiting additional Board members, we plan to edit and publish Marge Felder's writings on facilitating positive human development. Catherine Morgan will have some things to say on this topic, too. Other former HDA staff members may also want to contribute articles.

New Services and Programs

We're developing new programs, especially related to ways artwork can facilitate human development -- but not limited to this by any means. New personal growth groups are on the horizon as well. 

Alzheimer's and Joy

There's a growing need for a deeper understanding of how persons with memory and cognition issues can still have a joyful quality of life -- and how the people who love and care for them can share in this joy. We'll see how the writings and services on this topic evolve.


We're very open to suggestions and collaboration. Take a look at the 12 core values; see if they resonate with you. Send us your ideas, however wild they may seem. We love the wild; that's why we're based now in the woods of northeast Georgia!

Board Expansion

We are contacting potential board members who knew and understood Marge's work well, and who are equipped to help carry out programs based on our values and processes. HDA has no paid staff at present; as HDA evolves this may change.
