Mestichelli Barnes in my opinion is top notch dental practice. They have state of the art equipment and the office decor looks like a resort with fireplaces, balconies and ductless air conditioning. The staff is knowledgeable and friendly from the  front desk to many dental qualified dental hygienist. Dr Bill takes the time to explain the procedures in advance and performs them flawlessly. I would not hesitate to give their  practice a try. You won’t regret it!!!

I never fear going to this office, whether it be for a general cleaning or major dental work. They are truly wonderful people. The practice is innovative and has technology that other offices just don’t. A one stop shop! It has been a pleasure getting dental work done by Dr. Barnes and Dr. Mestichelli. I highly recommend them!

Lori B. from Broomall, PA (Source: Yelp)


I’ve been going to Dr. Bill for over 20 years. Dr. Bill and his hygienists (especially Dana and Yvette) are the best in Philly. They are gentle, caring and very knowledgeable. They put you at ease and they are honest and straight forward. One day last year, I had an emergency visit and Dr. Bill was not in but Dr. Barnes was able to fit me in and gave me back my award winning smile. I highly recommend this awesome dental team! Lori B.

I couldn’t take the pain it was unbearable coming from my back tooth Friday night I couldn’t asleep. I couldn’t wait for Saturday morning to come to call the office. Not thinking it was a holiday weekend (Labor Day) the office was closed and I knew I couldn’t stay in this pain until Tuesday morning. I called Dr. Mestichelli’s cell phone I explained what was going on and he told me to meet him at the office in 40 mins. He drove from NJ to accommodate me on a short notice. Who does that?? Dr. Mestichelli made sure that I was comfortable during the procedure which was extraction of a tooth it was quick and painless. He even followed up via text to make sure I was feeling alright. I highly recommend this office for your dental needs! I always leave with a smile on my face even if I can’t feel my face 🙂 THANK YOU! As a bonus: Dr. Mestichelli gave me a ride to Dunkin Donuts when we were done for a much needed coffee.

I recently had laser surgery on my lip. Dr. Mestichelli was patient and attentive to my feelings. He explained the entire procedure before and during each step of the process. He understood I was nervous. To my surprise he took the time out to call me that evening to see how I was feeling and if all was okay. The procedure went great. I feel that Dr. Mestichelli is not only a very good dentist he is also a caring and thoughtful person. I would recommend him to anyone!

Michelle S. from Philadelphia, PA (Source: Yelp)


My anxiety and fear of the entire dental experience has been completely dissolved through the “painless” dentistry of Dr. Mestichelli and staff. My sixth month check up and teeth cleaning was completely non-threatening and virtually painless. My fears are completely erased the second I walk into the office. The pleasant and cheerful staff at the desk begin the process – as it then continues to Nicole (who did an excellent job of cleaning my teeth) to Dr. Mestichelli for the ending check up. I recommend Dr. Mestichelli and his wonderful staff for complete dental care – care that dissolves fear and anticipation with the first, “Hello”.

Lauren J. from Yeadon, PA (Source: Yelp)


The entire staff at Dr. Mestichelli office are AMAZING!! The office manager Jacquelyn is wonderful, she goes above and beyond and I truly appreciate her. Was having a serious issues with a my flex spending account and with her help she provided all the information being requested. Her customer service was immaculate and very much appreciated. I absolutely love this office. Not a single complaint. I would highly recommend this office.

I’ve been away from Dr. Mestichelli for a few years for insurance reasons. Am so happy to be back. Some new players but the same welcoming, professional yet easy-going atmosphere!!! Dana did such a great job cleaning my teeth and of course Dr. Bill was his usual self: friendly, funny and completely thorough! It was the first time in a long time that I didn’t dread that trip to the dentist’s office!!!

Michelle Sumner (Source: Google)


Anxiety ridden over a tooth extraction – so needless!!! Dr. Mestichelli handled the entire task with professionalism, kindness and NO PAIN! Almost unbelievable! The process was over before I even had time to anticipate the worse. I left the office pain free and experienced no discomfort at home or today (the day after the procedure). There are NO words of thanks or appreciation to Dr. Mestichelli for making my experience so stress and pain free.

Dawn M. from Philadelphia, PA (Source: Yelp)


Love this office! They don’t push anything on you, they have Saturday appointment, weekday evening appointments. Staff is friendly, office is clean, modern, music in the background, latest equipment. Dr. M. is a down to earth gentle dentist. He doesn’t push anything on you. He doesn’t make you feel ashamed or guilty if your not up to par. He explains everything in plain language. The office is convenient and although there isn’t a parking lot, there’s plenty of street parking around the corner with a 2 hr limit and no meter. They will text you a reminder and you can respond to confirm your appointment. His son inlaw a dentist there too and I believe they offer additional services aside from dentistry. I think botox and other services. I’m definitely thinking about checking it. 5 star service all around!

Cathy T. from Philadelphia, PA (Source: Yelp)


I’ve been a patient of Dr. Mestichelli’s for well over 35 years! He is hands down the BEST DENTIST in the City of Philadelphia! The practice itself is a state of the art dental office!! The hygienists and staff are extremely friendly and they all make it a point to provide quality service and make your visit at the dentist as comfortable as possible. Again I can’t rave enough about Bill Mestichelli, he’s extremely thorough and is up to date with all dental services, treatments and procedures. And his prices are EXTREMELY reasonable!!!

Although going to the dentist is the least favorite thing that I enjoy at any time, ever since I’ve been going to this practice approximately 2 years now, I am beyond satisfied. Not only am I given exceptional service, I walk out every time very informed about additional steps that I can and should take to maintain a healthy lifestyle with reference to my oral hygiene. I highly recommend this office, the staff are simply wonderful and extremely professional.

My husband and I were in desperate need of a new dentist and we wanted to keep it local. We used a combination of Yelp Reviews & Aetna’s web portal to make new patient appointments with Dr’s Mestichelli & Barnes at their offer located conveniently just 1.5 blocks from our house. Needless to say–as long as they participate with our insurance they can consider us lifelong patients of their office! Although there was a small hiccup with what time our appointments actually were for (since new patients also have a “pre-appointment” to have an opportunity to meet with the Doctor), everything else went off without a hitch! They even texted me the day of to tell me I could come in earlier. Very cool. Michelle was the dental assistant who took my x-rays. By the time she was done I wanted to ask her to be my new best friend! Loved her! Yvette was our Hygenist and she could not have been more polite, thorough, and accommodating. I met with Dr. Barnes and my husband with Dr. Mestichelli. We were both thrilled. They were so friendly and informative. Their office was immaculate! The staff was fantastic! I can’t believe I actually enjoyed going to the dentist!

Marc S. from Springfield, PA (Source: Yelp)


What a great office staff and doctors. My family and I have been seeing Doctor Mestichelli for over 20 years and he continues to impress me with every visit. During one visit several years ago he found an issue that could have been extremely serious during a routine exam for my wife. Not only did Dr Mestichelli recommend a doctor but he was with us for every step of the way! I cant say enough about him. My Family and I are lucky to have him as a doctor.

Heather J. from Philadelphia, PA (Source: Yelp)


Love, love, love Dr Mestichelli and his staff. My husband and I have been coming here since we moved to South Philly about 7 years ago and I wouldn’t go anywhere else. They do great work- gentle and reasonably priced as well. I had a tooth pulled today and not only didn’t it hurt a bit, Dr Mestichelli called me this evening to check in and see how I was doing. Highly recommended!!!

Lee N. from Philadelphia, PA (Source: Yelp)


Dudes. This is THE best spot in Philly if  you want anyone digging around in your mouth. They’re awesome. I’m usually scared of the dentist but I went yesterday to get a cavity filled and it literally took 15 minutes and I didn’t feel a thing! I was so happy when I was done!! I highly recommend them! My fear of the dentist is over!

Lindy B. from Philadelphia, PA (Source: Yelp)


This dental practice is a wonderful neighborhood business that is very supportive of the local community yet which also is very professional and up-to-date – no ‘mom & pop shop’ here!  I highly recommend them (very friendly staff with smiles to go around – a practice which starts from the top, from Dr. Mestichelli himself.  A very friendly and welcoming man!)

Kerri Master (Source: Google)


I have been a patient with Dr. Mestichelli for over 10 years! I wouldn’t have it any other way. He makes you feel like a family member and genuinely cares. His team is respectful and very kind. They do not rush you out and will answer any and all of your questions as well as provide you with a “goodie bag” to continue your path of maintaining your teeth. The office is state of the art and SUPERRRR clean!! They offer a number of services and free consultations. You will not be disappointed.

I never liked to go to the dentist but since I have been going to Mestichelli and Barnes Dental Associates It has always been as pleasant and experience as it can be. Staff is professional courteous and friendly. My hygienist knows me and cares to remember things with discussed six months ago. The Drs. are all great informative and excellent Dentist with great skills. I trust their professional judgement totally. I am very happy to now go to the dentist without apprehension.

James D. from Philadelphia, PA (Source: Yelp)


It is always a pleasure to meet and greet the staff. It is a welcoming experience. I am sure that there are many who fear the thought of the dentist office. Not so at Dr. Mestichelli’s office. Dr. Mestichelli and his entire staff will set your mind at ease and eliminate any preconceived negative thoughts. Truly, an outstanding dentist.

Kathy M. from Philadelphia, PA (Source: Yelp)


Great staff –  extremely friendly. The office is warm and comfortable. I just went for my 6 months checkup and cleaning. The dental hygienst, Yvette DiSalvatore, and front desk people are considerate, caring and great professionals. Dr Bill is a great dentist who listens to his patients and takes care of them with great attention. He is also a great baker! He made Banana Walnut Muffins that were delicious – moist and flavorful. You never know – it may be a baking day on your visit.

I absolutely love Dr. Mestichelli and his staff! I’ve been a patient at this office for quite a few years now (over 20)! This office is a state of the art dental practice and Dr. Mestichelli is a “WIZARD” at dentistry! My hygienist, Dana, is fantastic, she is so precise and is very gentle! There aren’t enough words in vocabulary to describe how much I like this office!! Dr. Mestichelli is the best dentist in the City of Philadelphia!

Jill Milicia (Source: Google)


I’ve been a patient of Dr. Mestichelli for the past 30 years or more. I have always had a great experience no matter what was needed. Now that he has teamed up with his son-in-law, Dr. Barnes, the practice has become even better. State of the art equipment includes a piece that can produce a same day dental crown. The service provided through this office is just exceptional….

I have been going to Dr. Mestichelli’s dental office for many years. I was always petrified of going to the dentist but, Dr. Mestichelli cured me of that. He is compassionate and listens to you. His staff is excellent. I especially feel very lucky to have Yvette clean my teeth. She is wonderful! Explains everything she is going to do and has never hurt me. Love my dental office!

Acquanetta D. from Philadelphia, PA (Source: Yelp)


Dr. Mestichelli and his staff are second to none. His office is pristine at all times. I’ve been a patient since 1976 …I walk in, and everybody knows my name…( Like Cheer’s LOL)… I have a very low threshold for pain. Never had to worry about pain here. I look forward to my dental appointments. He numbs your gum before he gives an injection…so you barely feel anything. It may sound strange, but I actually start drifting off to sleep while having my procedure completed. The oldies playing in the background don’t hurt. So, if your looking for a ~ COMPASSIONATE PAIN FREE DENTAL EXPERIENCE ~ Call ~ Mestichelli Barnes Dental Associates …Tell them “ACQUA” sent you.

Kris M. from Philadelphia, PA (Source: Yelp)


I moved to Philly about a year and a half ago and have been using “I’m new to the city” as an excuse for that long to avoid seeing a dentist. I’d been seeing the same dentist for all my life up in North Jersey, and would try to make trips up there to see him because previous attempts at finding an equally reputable dentist by Glassboro (where I was living for four years up until I moved to Philly) had been nearly disastrous (money hungry, not gentle, poor advice, very outdated equipment, etc). But the two hour long trip to his office and his shorter hours were becoming convenient excuses for me not to go, so I decided I needed to stop being a baby and find a dentist in Philadelphia. I had pretty bad decay in my back top molars, and a previous dentist in South Jersey had highly recommended pulling them. The dentist from North Jersey (the one I’d seen all my life) was flabbergasted when I told him this, and insisted that they didn’t even need crowns, so pulling them was definitely not the way to go. I ended up having those teeth root canaled and resin done fillings on them (which are sort of a long term-temporary deal – I can have them like this for a few years, but will eventually need to have an “onlay” put in them). I’ll explain the importance of this detail in a minute. It had been two years since my last cleaning, so last week, I decided it was time to stop being a baby. I knew I had cavities in three teeth that needed fillings from the last time I’d gone to the dentist, and I had a feeling there might be one or two more teeth that may need attention. But when I started to do some research into local dentists, I saw in many reviews that dentists around here are too filling-happy (they say you have an inflated number of cavities, but when people get a second opinion, they would be told they had half as many or only one, etc.). That worried me. I quickly eliminated about half of the dentists I was considering because that feedback came up often in their reviews. I didn’t see any of that in the review of Mestichelli Barnes’s office, and they were three blocks away from me and had stellar reviews and credentials, so I decided to take the leap. The receptionist I spoke with was one of the nicest people I’ve ever spoken with – such a sweetheart! She found a cancellation that allowed me an appointment two days in the future at a time that worked perfectly for me. I went in and was brought back before I even finished my paperwork – very prompt. I don’t even think I was sitting in the waiting area for five minutes! The hygienist was also one of the most friendly people I’ve met. She even took me on a quick tour to show me the facility, which is very clean and attractive-looking, and filled with high-tech equipment. We finished up my paperwork and I walked her through my history and the situation with my molars, and she was x-raying me within 10 minutes of my arrival. She had a great “bedside” manner – she talked me through everything that was happening, which is a detail I think a lot of people will really appreciate. The x-rays are digital, so everything was immediately viewable. She then quickly got to work on my cleaning. As I mentioned, it had been two years since my last cleaning, and with the amount of sugar and coffee I ingest, I was worried it was going to be painful. However, she let me know I’ve been doing a pretty good job at keeping them clean, and there was just a little bit of buildup around the inside of my bottom front teeth. That part was a little uncomfortable, but not to her fault – it was overall the fastest and most gentle cleaning I’ve ever had, and was still very thorough. My teeth look great!! Dr. Mestichelli came in right after my cleaning to look at my x-rays. He echoed the opinion of my childhood dentist, that the onlays on the back molars were definitely the way to go, and also said that if they weren’t bothering me, he would recommend leaving them. What a relief! – I was worried a dentist was going to pressure me into getting the onlays put in immediately (which means more money for them) when the temporary resin fillings are holding up just fine. This is when it really was confirmed to me that I was really in good hands. He also said I only needed three fillings on the same teeth I’d known about, and we scheduled an appointment two weeks out for those fillings to be done. Overall, he was very informative and friendly. Overall, I can’t sing enough praises about this office. They were clean, friendly, accommodating, patient, and reassuring from beginning to end. I’d give them six stars if I could. Even if you’re a “fradey cat” like me when it comes to your teeth, please just bite the bullet (ha) and do it – you’ll be so glad you did. So thankful I found this place!

Beautiful, immaculately clean office, waiting area and dental area w/ up-to date equipment. Employees appear to be very pleasant, and considerate of time. Hygienist was thorough,(although I will remind her to floss under my bridgework next cleaning), answered questions appropriately and was gentle with cleaning and other procedures. Recommending Dr. Meshtichelli to family members and friends.

They have changed my impression about dentists. I was so scared of dentists but this practice is alleviating that fear. I feel no pain when i get a shot or during the procedure. They are so patient and friendly. Also this is the only practice where your appointment time matters…i have never waited beyond my appointment time.I have seen Dr Mestichelli and also Dr Barnes- both are amazing doctors .I highly recommend them.

Rachel K. from Philadelphia, PA (Source: Yelp)


We love Bill! My ‘gent and I have been seeing Dr. Mestichelli for the last few years and couldn’t be happier. His office is clean, inviting and modern, and his work is gentle and professional. I’ve never had such painless dentistry. I’ve previously used dentists in center city and Old City, and they don’t even compare. His office also offers early evening hours, which is super helpful. I can’t say enough nice things! It’s such  relief to find such good care in our South Philly neighborhood.

Laurie Fin Churchill (Source: Facebook)


This is a very brisk office with a very competent, friendly staff who are eager to assist with any dental concerns you may have. I have been treated by both Dr Barnes and Dr Mestichelli and can recommend both without hesitation. They will accommodate an urgent issue quickly and with compassion.

I had an appoint with Yvette for a cleaning. Yvette was very thorough through the entire process. We spoke about my grinding and Yvette was able to get me to take the impressions at the cleaning appt for a night guard that I had been needing! I would recommend Yvette as well as the rest of the staff at Mestichelli Dental.

Heather Jarjisian (Source: Google)


These guys are incredible! I made an appointment on my lunch break and thought I would need to take extra time, but they had me in and out so quickly. Completely bypassed the waiting room – they had everything ready. Incredibly nice and there was zero judgement, I felt no guilt at any point which is so different! If I could leave more than 5 stars I would – this is coming from a former dentist-hater.

Robert Terranova (Source: Google)


My experience at Mestichelli and Barnes was very positive from moment I arrived until the appointment was finished. The dental hygienist, Kim, was excellent and made me feel very comfortable as she explained and did the X-rays and cleaning. Dr. Mestichelli was also very professional in his examination and explanation.
