I've experienced consistent high hospitality service level at Sommer's for over 9 years of sales and service. My sales experience with Jim Naus was excellent. I appreciated his attentive but no pressure level at Sommer's for over 9 years of sales and service. My sales experience with Jim Naus was excellent. I appreciated his attentive but no pressure approach, always checking in if questions and very responsive.
