D&H Distributing

Michael and Dan Schwab have tightened D&H's vendor relationships, launching training and incentive programs to double its Hewlett Packard Enterprise business and quadruple Meraki adoption among existing Cisco partners. The distributor added Microsoft Azure to its new cloud marketplace in a push to at least quintuple the number of channel partners using the platform. And the Schwab brothers ensure the company never takes its eye off the SMB ball with the rollout of an additional $115 million in extended credit lines.
