First is ineffective verbal skills. Most management consultants start here with a new client. When your environment is not congruent with what you're expecting your patient to accept, then expect your acceptance rates to be significantly lower than they could be. It's common for doctors who have just moved into their new office to report a high incidence of existing patients asking for treatment that was presented years before. But that only occurs when the new office has a visual image that is consistent with the quality of care they provide.
People react much more to what they see and feel than what they hear.
Remodeling is usually the least optimal choice unless sufficient additional space can be added and the construction can be phased so that production is not lost due to partial or complete shut-down of the practice. A high percentage of doctors who have been through a major remodeling while trying to conduct a busy practice say that, even though they are pleased with the result, they would never do it again. They would move to a new space instead. Leasing a new space is a good choice when land is not available in appropriate amounts at a reasonable price or if you don't have a sufficient down payment. A new building is usually the best choice when possible.
