Hello,
I thought I would weigh in since I am completing my Renal fellowship soon, and have signed a contract for a job, so I think I can offer some perspective. I am currently in the SW region of the US, and have taken a job in this region. I interviewed with several groups, the salaries offered here varied btw 175-195. Most offered partnership after 2 years, the current partners in the groups were making significantly more than the starting salaries.
Dialysis is getting more costly, and the cost of doing dialysis are on the rise, adaptation is important for any physician. Most middle to large size Renal groups (including the one I ended up joining) are attempting to increase revenue by other mechanisms such as access centers.
I am very happy I chose Nephrology, and I am satasfied with the salary, and potential to earn as a partner. My wife is currently interviewing for Hospitalist jobs, and although our initial salary is in the same range, currently the long term earnings are larger.
I hope this was helpful!
