Dentistry is one of the most difficult professions to master. You not only have to be an excellent clinician; you must also be an expert in many different areas of your business (e.g., effective communication, team leadership, team inspiration, business systems, capital expenditures, profit and loss statements, business growth strategies, marketing).
This means that you must wear many different hats. You are not only the owner/CEO, but also the COO, HR director, marketing director, bookkeeper, and of course, the clinician whose services generate revenue. Unless you happen to have superhuman powers, there is no way that you can perform optimally in all of these areas without help.
You need a mentor — someone who has achieved the level of success that you aspire to and who can teach you how to get there. Sometimes, mentors are also consultants. I have had many mentors over the years; some were great, some were not, but I learned extensively from them all. The great mentors helped me to grow my business rapidly in ways I could not have done alone. The not-so-good mentors cost me a lot of time and money. On the bright side, I learned what not to do in my practice!
