Dr. Sladek is a wonderful doctor. He takes time and listens. He doesn't mind answering questions.

March 11, 2020 7:33 AM

I think that the office staff needs to be quick answering the phone. The office staff also needs to return phone calls faster - this includes docs & nurses.

My daughter was ill at school on 10/29/18. Picked her up and took her to doctor's office. I had just left doc office about 1 1/2 hours before bringing her to doctor's office. I had made appt. for me for 11/23/18 with regular doctor. I had mentioned while in doc. office about me getting flu shot. And they serviced me also. Very nice & polite with a smile. I wish I remember the nurse's name - she was great. I never even felt the shot - she was very nice to my daughter. The doctor was very nice as well. They made it a very good visit with no appt. time. The receptionist on duty 10-29-2018 was very polite and helpful with the questions I asked. She had greeted me with a bright smile. Keep up the great job!!

October 25, 2018 7:00 PM

I appreciated this provider because he was more interested of my health conditions and had suggestion, even had me do a little stretching as to the mobility of my physical being. After leaving him I really felt that I had seen a "doctor".

October 21, 2018 7:00 PM

Left the office with a smile & good spirits!

September 13, 2018 7:00 PM

The doctor had answered my questions and given me various solutions to my medical condition, etc., when I had saw him on 08/17/18.

April 11, 2018 7:00 PM

I think Dr. Sladek is the most knowledgeable & the absolute best dr., but very hard to get an appointment with.
