Here are some of the sites that I have built and am currently nurturing. In terms of style, there are some older sites lower down this page that are theme based with very few configuration options. This doesn't mean that they won't rank well or generate contacts from prospective clients (which is ultimately what you want).
Later examples near the top of the page are totally bespoke because that is the way I prefer to build sites now, starting literally with a blank screen and adding key elements to it. So if you have a design in mind I can probably build something very close to it.
The key thing that I always consider is responsiveness to different screen sizes. Research suggests that over 50% of people now access the internet using their phone or tablet rather than a desktop/laptop so it is vital that your site performs effectively on smaller screen sizes as well as larger ones.
A highly successful web site (based on the response rate) built around a modern responsive theme which uses a vertical menu structure to show the large volume of content available. This site also uses a video which not only helps with optimisation but also gives potential clients an idea of whether they can work with the therapist.
