There are none unfortunately. I've found Vultr to be good value if you really need dedicated servers, OVH probably as well. However, a Hetzner VPS with dedicated CPUs in the US is still less expensive than the equivalent dedicated server at those providers.

Hetzner does now have US based locations. However, as far I can tell, they are restricted to their cloud products and not their line of dedicated servers

OVH has a location in Canada (east coast), not quite as cheap as Hetzner though
