Jeffrey P. Ossen, the owner of Stonegate Manor, has been in the manufactured housing business for 35 years, and has been a leader in the industry for most of that time. He was the founder of the Connecticut Manufactured Housing Association and served as its first president. Jeff continues to serve on its board.

Earlier, he was president of the New England Manufactured Housing Association, which had been founded in 1946, and was terminated in 1995 by agreement of all so that individual state associations might take its place. His term as president of NEMA was the longest of any person ever serving in that office.

Beginning in 1967 with one 13 space park on a gravel road in Mansfield Center, Connecticut, Jeff has built a company with manufactured housing communities in three states, composed of almost 900 sites. These communities are operated under their individual names, but under the collective title of "Mobilehome Parks of Jeffrey P. Ossen."

The offices of this enterprise are at Stonegate Manor, the largest of all these communities.

Prior to his decision in 1981 to devote full time to manufactured housing, Jeff practiced law in Mansfield, Connecticut. This followed a stint as Assistant Professor of Business Law at the University of Connecticut in Storrs.

Jeff is a graduate of Torrington (CT) High School, the University of Connecticut (with High Honors), and Harvard Law School. He also holds a Masters degree in political science from UConn.

Long a believer in community service, Jeff is a long time member of the board of Windham Hospital in Willimantic, Connecticut. He is currently serving as Treasurer and chair of its finance committee.

In prior years, he was a member of the Mansfield Town Council and also Mansfield's Deputy Mayor. He later served as chair of the E. O. Smith High School's building committee at the time it became independent of UConn and was designated Region 19. Subsequent to that, he was a member and chair of the Windham Region Transit District.
