Isaiah, despite being of average height and build, seems a large man that fills every room he enters. Dressed tastefully and neatly as befits he personality, he has a knack for procuring clothing which should normally be reserved for those above his means. While not unduly handsome, he cuts an dashing figure and is tolerated at high society dinners and club parties far more often than not and seldom with an invitation. In his private moments, he is a studious man, in a state of constant self-education and reads voraciously on every subject possible. Knowledge for its own sake is an unfailing pursuit.

He is bald with a thin mustache and beard which encircle his mouth and chin but do not continue up his cheeks. His face is turned upward in a perpetual smile that seems to indicate he knows more than he lets on and his boisterous personally is always optimistic and cheerful.

His voice feels loud even when he whispers and he has impeccable diction and a wide vocabulary indicating a formidable education. He sports none of the typical New York accents despite spending most of his life there, a fact of which he is enormously proud. His amiable demeanor reaches from his smile to his eyes and bursts forth in his exuberant speech and he seems incapable of being offended.
