Established in 1993 by Charles Helscel, Tyann Development has firmly established itself as the premier real estate developer in Northeastern Oklahoma. “Tyann” was a nickname Charles had for his wife, Charlotte. He promised her that one day he would put her name in lights, so when he started the company it only made sense to call it Tyann Development. Tyann Development is a family owned real estate developer that is operated in Owasso, Oklahoma. Over the years, Tyann has had the privilege to provide real estate development services for many different segments and expand our development capabilities.
