Being a practice owner allows you to do things that you can't do when you work as an associate such as setting your own working hours, lunch hour, patient scheduling, staff hiring/firing, instruments and supplies. Owning a practice, however, doesn't neccessarily guarantee that you will be happier and earn more money. I've seen a lot of older docs who sold their practices and went to work for the corp offices for better income and fewer headaches associated with running a practice. These older docs no longer produce the same income that they once did when they were younger. In order to maintain the same level of success as a business owner, you have to spend a lot of time to manage it. As soon as you let the outsiders (your office manager, associate dentists, consultant etc) manage your office, it will decline quickly. The staff become lazier when you are not present at your office regularly. Patients choose you because of your good reputation. When you are not at the office regularly to take care of them, they will go see another doc.
I've also seen young docs who made poor decisions in purchasing an existing office or spent too much money to build an office from scratch. They were not able to attract enough patients to pay for the high overhead. They gave up and went back to work for the corp or for another practice owner.
I too was scared of taking out additional loan to open my practice when I was a new grad. Like many new grads, I rushed for immediate gratification. I leased nice cars, bought a house......and worked 6 days/wk to pay for these shinny new toys....and life was good. I had worked for the corp for 4 years before I finally had the courage to start my own office from scratch. With close to $1 million in debt ($450k student loan, $380k home loan, 2 leased cars etc), I didn't want to take too much risk. I had $55k in my saving (for rainy days) and I took out a $75k business loan to build a small 1350sf ortho office from scratch. I didn't want to downgrade my lifestyle so I continued to work F/T for the corp and worked at my newly built office, which didn't have a lot of patients at the beginning, on Saturdays and Sundays. As my office got busier, I slowly cut my associate days at the corps and only worked part time for them. Currently, I work at my own office 12 days/month and 11 days/month for the corp. It's the best of both worlds: when my office doesn't produce much during the slow months between Sept-Jan, I still have a fixed steady income from my P/T corp job. Being an owner, I get to decide when I want to work.... 8am-noon onthe weekends and 2-6pm on weekdays. Low overhead is key....when you have fewer bills to pay, running your own office becomes more enjoyable.
