Dr. Vassos B. Hajiharis

Courteous, professional service

Dr Hajiharis and surgery assistant Cynthia were fantastic! Cynthia was very professional and attentive to all that I needed as a patient and she included after-care directions. Excellent overall The Doctor talked me through all that he would need to do along with added information that I appreciated.

My visit with Dr.Hajiharis went very well. Dr. was very polite, efficient and knowledgeable. I felt very. confident and assured that I had good care.

I had two wisdom teeth removed and it couldn’t have gone smoother. After hearing nothing but horror stories from friends and family, the whole experience was really a breeze. The initial consultation was thorough. The day of surgery, I had all my last minute questions answered and was in and out. My post op recovery was not as bad as I expected. As far as surgeries go, this was easy.

Today was an outstanding experience. Dr. not only removed my impacted molar and the tooth next to it he also made me aware of his continued concern about an impacted molar on the right lower jaw and symptoms to watch for. Bridget and the Dr. were gentle, considerate and and helpful on all levels. I will definitely return to him as needed and gladly recommend him to anyone needing an oral surgeon.

I love Dr. Hajiharis and his staff. Everyone puts you at ease and is kind, professional, and caring. I had an implant today comfortably performed and with minimal pain post procedure. I would not hesitate to recommend Dr. Hajiharis.

Very friendly office staff and Dr. Hajiharis was excellent. Being a dental "chicken", I experienced little pain great service and the staff and Dr. Hajjiharis were Covid ready. If needed I will not hesitate to return.

Everyone at Midland treated me with the utmost professionalism. Dr. Hajiharis put me at ease during the consultation and I trusted him completely with my procedure. I would highly recommend him to others.

The entire process was comfortable. Each step explained and executed smoothly. Was in and out after completed procedure in short order.

I believe this is my 3rd tooth extraction done here, so I speak from a decent amount of experience. This place is the greatest! Everyone is friendly and knowledgeable. I've always had Novocain, and they know just where to inject it and the proper amount to give so you have absolutely NO pain. I never thought I'd be able to say that about a tooth being pulled! And they don't waste time, the procedure is very quick and you're out in no time. I highly recommend this place.

This was my first time at Midland Oral Surgery in Tinley Park and I saw Dr. Hajiharis. Dr. Hajiharis was very thorough, explained in detail his diagnosis and next steps to address the issue.

Had an infected wisdom tooth. My dentist prescribed an antibiotic and referred me to Midland Oral Surgery. Dr. Pagni removed the tooth, quickly and pain free. Very warm and helpful staff, efficient and comforting. Would definitely return to this practice and would recommend family and friends.

From the first time I made the appointment I knew this clinic was amazing. Prior to coming in I received two texts one week before and one day before to remind me of my appointment. When I first entered the door I was greeted by this extremely happy, friendly and informative receptionist explaining everything I needed to fill out in great detail which set the tone for the rest of my experience. I only waited for 10 to 15 minutes before I was called for my appointment. When the nurse called me in she was all smiles and made me feel comfortable. I had to do another x-ray and found out I needed to have two teeth pulled instead of one. This made me extremely nervous. When I met the dentist he had a very calming voice and made me feel relaxed. He assured me everything would be fine and it was. The procedure didn’t take very long and the nurse explained everything to do after in great detail. I was sore but today I’m feeling much better. And it’s only been 24 hours. Thank you all Midland Oral Surgery at Tinley park. Especially Dentist Bill Hajiharis.

I just had 2 wisdom teeth removed yesterday and I can say with 100% honesty that every person there was so professional, patient, kind and informative. I was extremely nervous to have the procedure done but the nurse I had and Dr. Hajiharis were both wonderful. They answered any questions I had, reassured me of what was being done, gave me detailed instructions for aftercare and even gave me the cutest little ice packs! Plus it was done so quickly, I didn't think it even happened when I woke up! Thank you very much to all staff at Midland Oral Surgery in Tinley Park!

My 14 y/o freshman daughter needed 7 baby teeth ( a few were submerged) extracted, to expedite her getting braces before she is in college. This was her first medical procedure other than regular dentist and doctors visits. The whole staff, at Midland Oral Surgery ,was wonderful. They did a great job at trying to set her at ease. Dr Hajiharris has a great rapport with teenagers. My daughter said she didn’t feel a thing , they sedated her and next thing she’s in recovery feeling funny. The whole experience was GREAT. The nurse was fantastic.

I had an impacted and very infected wisdom tooth. The dr told me what he would recommend and then gave me the option of what I was most comfortable with. I went in for a consult, however after looking at my tooth and seeing how badly it was infected, I asked if we could do it now an he readily agreed. I told him I was really nervous and he made me feel comfortable and had me laughing. It was over before I knew it. The only thing I’d complain about was the long wait, however I have been here before for my son and didn’t wait long so they may have just been very busy.

This is our third time receiving the outstanding oral surgical services of the MIDLAND ORAL SURGERY GROUP. Once in Frankfort and twice in Tinley Park, both offices are staffed with very friendly, competent and compassionate professionals. Appointment times are honored, no wait time. We were especially impressed that the temporary closing of their Frankfort office, due to a flood, the day before our appointment, was reschedule at their Tinley Park office without a glitch. We were very impressed that the change of location only affected our appointment time by 15 minutes. We arrived early and had no wait time. My 94 year old mom with diminished abilities was addressed, treated and serviced with tender loving care - what a blessing. Her services were delivered quickly without any of the complications that we were advised could occur. We left their office with written instructions, after surgery items for at home care and an assurance that someone was available 24/7 for consultation or direction for any additional needed care. We were sent off with the expectation of the best outcome for my mom. Kudos to the administrative, nursing and dental staff; no place does it better.

I was given wonderful care from the beginning to the end from the dental assistant through the dentist to the checking out procedure. My care and comfort in a stressful situation was appreciated. I wasn't rushed but felt that everything that was done was for me to have the best possible outcome. It was.

I love the entire staff at Midland. Just brought my third child in to have wisdom teeth removed. It took less than an hour from the time we arrived until the time we left. Dr. Hajiharris is professional, friendly and kind. As well as the rest of the staff. They explain everything, ease the patients nerves, and ask for questions at every step of the experience. I would and already have recommend them to others.

Best experience from a provider in a long time. Staff is friendly, efficient and caring. All my questions were answered and when I had further concerns, those were addressed thoroughly and in a timely manner. I had two teeth extracted and 3 implants put in at the same time-all with very little discomfort later on. I would recommend Midland Oral Surgery in a minute!

Every staff member I encountered was friendly and informative. Yesenia (hope I spelt her name correctly) was so sweet and attentive. She was willing to go above and beyond to answer my questions. Dr. Bill Hajiharis was fantastic too. Very thorough with no surprises. He does a very good job of trying to calm you down if you're nervous. Hopefully won't need to do this again, but if so, this facility would be my number one choice.

I would recommend Midland Oral Surgery and Implant Centers for anyone looking for a beyond Professional and Curtious Staff. Dr. Hajiharis is one of the most down to earth Oral Surgeon's I have ever met! A couple of years ago I started the process for Consultations for All on Four Dental Implants. Dr. Hajiharis stated my Lower Arch All on Four in March and Today was the Start of my All on Four upper Arch. He is so genuine, funny and truly cares about his Patients and is up to date on all current Dental Procedures. I definitely made the right choice. Thanks Dr. Hahiharis for the start of an awesome smile I have been waiting for and making me SMILE AGAIN.
