All types of businesses have websites in order to attract customers and to have a competitive edge on their competition. The medical industry has just started figuring this out. Doctors may be the last profession to discover the power of the internet. They can really take advantage of this by having a medical website design in order to be a reliable resource for patients and also to attract new patients. Doctors such as plastic surgeons still do have a better grasp of the benefits to having a website.
Other specialties such as Ob/Gyns are just discovering the benefits and marketing leverage a custom website can have.
