2 referrals per week is more than most. I worked at a well-known group practice and i never got more than 1 intake per month. It took 1-2 years for people to get 20 plus patients.
That's great. I think if you are resourceful, a good clinician, and are willing to work long hours, then good money can be made. You probably have to put in 60 hour weeks and work late at night, but its better than making 20K at a freakin post-doc these days. 25 patients per week would be my max personally--i don't have the stamina to see more.
One quick question, if you see 30+ patients per week, why do you need an additional job to accrue hours? Can you count report writing, notes, phone calls as part of your hours for licensure in California since you are clearly putting in more than 40 hours per week? They don't have to all be face to face hours from what i've heard.
