FP, according to Medical Economics magazine, is in somewhat of a funk. Salaries have not kept up with inflation over the past 5 years, even though the government proclaimed a "shortage" just 5 years ago.
Having said that, Southern California may have the least favorable job market for (any)physicians, due to oversaturation and managed care penetration. Starting salaries (in general) are between $100-125k, with 125k in the midwest and closer to $100k in California.
