A Message from the President of the Board of Directors

Throughout its history, The Institutes of Applied Human Dynamics, Inc. has had many loyal friends who have given new meaning to the old adage, “United We Stand.” Due to the devotion of our friends and supporters, not only does IAHD stand for advocacy and commitment for individuals with developmental disabilities, but it stands proud of what it has accomplished in the past and hopeful of what it can accomplish in the years to come.

IAHD’s extensive system of services supports individuals across a wide age range and broad spectrum of challenges. We have made great strides as an agency and as a part of society, and the recognition we have received from the educational, therapeutic, business, geographic and political communities speaks to the quality of the services we provide and additionally demonstrates the value that society places on quality life experiences for all people. As we have for the past 50 years, IAHD intends to continue to develop and operate opportunities to support individuals with developmental disabilities and their families so they are able to achieve a quality of life that reflects their choices, hopes and dreams.

IAHD’s continued growth depends on our ability to encourage more people to become involved with our organization. We invite you to learn about us via this website. Please consider joining us as a friend or a volunteer of IAHD and help us take another step further towards ensuring a brighter future for the people supported at IAHD.

Thank you.
Mary K. St. Mark, President
