Donald Ferguson, Chairman of the Board

Donald Ferguson founded Land Dynamics in 1979, responding to a need for doctors to be closer to the communities they served and for patients to more easily access their office buildings within a more aesthetically pleasing environment. With a background in motivational program sales and finance, he started the business by highlighting the advantage of a medical office condominium concept to doctors in the early hours of the morning as they prepared to perform surgery at local hospitals. Don eventually secured enough investors to construct his first 24,000-square-foot medical office building which became the beginning of a successful real estate development company. In early 2018, he stepped away from his responsibilities as Chief Executive Officer of Land Dynamics, but continues to remain engaged in the business as Chairman of the Board. As an active individual, this change has allowed Don to devote more time to other activities such as co-authoring books on self-improvement, traveling, hiking, biking and skiing.
