Thanks all for the advice. I'm definitely recommending combining everything into one site. Right now he's got 2 sites, each focusing on different aspects/services that he provides. Any recommendations on how to effectively leverage the traffic he's already getting to the 2nd site (that I'll remove)?
Also, can anyone point me to examples of sites that have effectively optimized for multiple services on the same site?
To give a little more background, this client offers a number of related services, including doctor assisted weight loss and hormone therapy (among several others). Many of his competitors only deal with one of those services, so their sites are all about weight loss or hormone therapy. My client's concern is that a potential patient will come to his site for, say weight loss, and be turned away because it's lost among all of the other services, while his competitors are clearly all about simply weight loss.
As EGOL noted below, this client thrives on cross-selling his services, and in my mind one of his main selling points is that he is a one-stop-shop for multiple, related services.
