Several ways - not necessarily mutually exclusive:

(1) Get your own local domains into the global DNS ? If it is a domain
you own, you can nominate yourself in the DNS. The upstream name
servers will go back and ask your name servers and things "should just
work".

(2) In /etc/dhcp/dhclient.conf  add:

    prepend name-servers 1.2.3.4;

or similar.

(3) Install the "resolvconf" package and update
/etc/resolvconf/resolv.conf.d/head - this file is the top "fragment"
of the (now generated) /etc/resolv.conf file

There may be other ways I cannot think of off the top of my head

Hope this helps
