You are the one who has to get up 5 days a week and go to a job. If you love being in the medical field, by all means sweetie, pursue this opportunity.
Benefits are a very important part of the "package". And if he is willing to at least match your salary at first, that is good. You can also ask him in the interview regarding job performance = raise after how many months.
I'm sorry, but this is YOUR life, not the life of the people you are working for now.
Please, do what you honestly think is best for you. Ask yourself, if I could have the medical field job, which I love and truly want, and better benefits, but I don't take it...am I going to go to work every day "kicking" myself and not being truly happy?
Hope this helps in some small way.
