Crisp and professional, this name exudes reliability and straightforward charm. The Scandinavian-influenced styling gives it a clean, Nordic coolness that appeals to contemporary tastes. It's substantial enough for a CEO's nameplate yet friendly enough for a kindergarten cubby label. The name strikes an excellent balance between familiar and distinctive—recognizable enough that people won't struggle with pronunciation, unique enough that your son likely won't share it with classmates. There's an understated confidence here, a name that doesn't need to shout to be noticed. It ages exceptionally well, maintaining appropriateness from childhood through retirement, and works seamlessly across casual and formal contexts.
