Mold in my office, do I have options

[Sean Price]

Along with diving into the realestate investing world, my primary job is I am a Chiropractic Physician.  I am having an issue with my office that I lease in that I have mold in the office (has been confirmed through a mold removal company coming and and evaluating).  The mold is not black mold, but the office has a very strong musky smell that gets worse as we get into the summer months.  

My question is this, the owner of the building denies the existence of an issue and has done nothing to remedy the situation.  What recourse do I have to force the repair of the situation?  Can I withhold rent until the situation is remedied?  Can I threaten to move and have them carry expense since they are not providing a sanitary office?  

I am in Florida and I am not sure what my rights are with this situation.  Thank you in advance.
