Exempt if only 2 employees?

I have been working for a medical practice for a year. My title is office Manager however I only supervise 1 person, the receptionist. Most of my time is spent helping patients with physical therapy, scheduling patients, or billing insurance. I am paid by the hour.

I work 9 to 10 hour days 4 days a week and an 8 1/2 hour day the 5th day of the week. I get a 1 hour lunch that is not paid. I do not get any other breaks. As a requirement for employment I also have to attend training seminars 4 to 5 times per year. They are usually on weekends and I am not paid for them. I have also been forced to attend a training seminar unpaid on a Friday, thus losing pay for that day also. For these training seminars I have to drive to LA from San Diego.

I have three questions:
1) If a business only has 2 employees are they exempt from overtime in California?

2) Are training seminars that are required for employment payable time? Is travel time also payable time?

3) Are there any attorneys willing to speak with me that practice in San Diego?

When I figured the amount I was owed I came up with a little under $3000. However this practice of not paying overtime goes back at least 2 years with aprox 4 employees. The other current employee does not recieve overtime either and is interested in getting help recovering lost wages.

Any help will be appreciated. Thank you for your time.
