So glad Dr. Krochak mentioned the PRP injection to me for my chronic knee pain. After the 1st injection it was like night and day, for the first time in months I could out pressure on my knee pain free. For me PRP was a miracle, but also many kudos to Denise and her staff in Woodbury as the somehow found a way through a multitude of insurance issues and got the job done! Highly recommend the folks at O&C, top of the line!
