I just started checking this site and saw your review. Totally unacceptable! I would never knowingly turn away a sick person for being a few minutes late. I will pass this on to my practice manager. My rule in the office is if a patient is late they can never be turned away by front office staff. This can only be authorized by a provider and we all know that sick patients don't get turned away. Thank you for your comments and I am so sorry. Dr. David Yablonsky

Dr Yablonsky takes time to talk to you and DOESN'T make you feel like an idiot. He is more interested in treating you as a whole person and NOT just a dollar sign like many other doctors.
