Dr Persak was extremely professional and kind when diagnosing and taking care of my corneal ulcer. I was able to get an appt within a few hours and after seeing Dr Persak, felt confident the ulcer would resolve shortly. I can confidently and highly recommend Gregory Persak, MD. I am sincerely grateful for his clinical expertise.
I have been blessed with this wonderful Doctor who gave me the gift of sight in both my eyes with surgery 5 years ago when i started to get glaucoma and my vision was failing. I am so thankful that he was able to help me with my issues. Keep up the great job Doctor Persak.
thanks Miriam
Dr. Persak performed my cataract surgery a few years ago, and I achieved an excellent result. My vision improved significantly. Since then, I undergo a series of exams regularly. Both Dr. Persak and the professional and technical staff are not only excellent but also very kind. It's a pleasure to go to my regular appointments.
Had a metal chip in my pupil that was excruciating. They took me right in as an emergency.
