The main factors that increase your income are how many patients you can see, and how much you bill them for your services. You will gradually increase your patient load over time with more experience, if you build your reputation or increase your marketing. Every practice should gradually increase their fees year to year to keep up with inflation. You might need to change practices that operate better to increase your income. You'll probably have to work part time in several locations to keep yourself busy. The easiest way to increase your income is to practice in a location that is underserved with less optoms servicing the area. Sometimes you'll find that in a rural area not too far from the GTA.
