While residential remodeling will always remain close to their hearts — and a large part of their business — Joseph and Patricia Karoly have discovered a niche in remodeling dental offices. The company has clearly made a name for itself in the community, as evidenced by its 75% referral rate from dentist clients.

The dental-office updates yield profit margins large enough to let the Karolys focus their residential remodeling business on projects they can't resist. The company has adopted the professionalism of this niche in more ways than one, giving all employees uniform shirts to wear every day.

Monarch hasn't forgotten its other clients, either. The company maintains positive relationships with past and current customers by sending out quarterly newsletters.
