To our valued patients
We would like to wish all of you a safe, happy and healthy holiday season. I know that 2020 has been difficult, but I have hope that 2021 will be a better year. We will continue to be open and operating at full capacity for the foreseeable future, continuing with all of the same safety protocols that we initiated when we reopened in June and which have proven to be extremely effective. Thank you for allowing us to continue treating all of your dental needs and for your continued support.
2021 will bring some changes to our office. First, I would like to introduce Dr. Alexandra Hochster. Dr. Hochster is going to be replacing Dr. Philip Afshar who will be moving to North Carolina in early January. Dr. Hochster has been working at The Rose Tree Dental Group since 2013 and we are excited to have her on board. I would like to thank Dr. Afshar for his hard work and quality care for the past year. We wish him well in all of his future endeavors.

I would also like all of you to know that as a way to help start your year off right and look your best in 2021 we will be offering a 15% off special on new Invisalign cases and all whitening procedures for the month of January.
We ask that if you are traveling for the holidays please pay attention to all Pennsylvania travel and quarantine restrictions. Anyone traveling out of state must quarantine for 2 weeks, no exceptions. If this effects an upcoming appointment you may have, please contact our office.
Thank you again for your continued support and we wish you the best in the coming year.
With warm regards, Dr. Jonathan Siegel

Great service, promptly called back for my visit on time. The hygienist Rosemary was very thorough and kind with my cleaning. My teeth were fine, so the dentist just barely popped in to give me the all clear. Receptionist Drew was helpful in updating my insurance and scheduling my next appointment. Overall great experience and will be continuing to come to Dentistry at 1818 Market!

I had the best dental experience ever. All the staff were polite, friendly and professional. They explained every detail of my exam and cleaning, step by step. After my cleaning I literally said “that was the best cleaning experience I’ve ever had”. I’ve been to the dentist plenty of times but I’ve never had a doctor explain to me how to properly take care of my crown and what to look out for. They made it so comfortable for me to ask questions without judgement. If you’re looking for smooth, professional dental services this is your place.

I have been going Dentistry at 1818 for over a decade and find Dr Siegal to be super compassionate and great. As someone who doesn’t need much more than cleanings, I think most of the team is professional, nice and quick. Shout out to the hygienist, Bisa for her humor and excellent cleaning. She made it a pleasure. I highly recommend going here.

I am very pleased with the care I receive at Dentistry at 1818 Market St. To say that my hygienist, Barbara, is superb would be a deep understatement. She is quite thorough; explains exactly and precisely what she's doing all throughout the cleaning process, and; she gives you a very detailed explanation of what she has observed about everything concerning your teeth, gums, bone structures of your jaw---even your tongue health! But what is so impressive, in addition to her clear dedication to performing an excellent job, is her sheer enthusiasm for her profession and for the biomedical research done in the dental field. She respects her clients such that, if she detects that you are the kind of person who wants access to this type of in-depth information, she will point you in that direction directly. She firmly believes that a great deal of her job is educating her client as much as possible. Last (if she has them in stock), you get goodies! After my first teeth cleaning with Barbara earlier this year, among other things I received a neat tongue scraper--an invaluable little tool so that now I don't have to use a spare toothbrush.My attending dentist, Dr. Jonathan Siegel, is deeply knowledgeable, approachable and friendly. One of his best methods is the in-depth conversation he has with you during the initial consult. Be prepared to not have your cleaning that first visit, but your x-rays and bite wings will be taken and a careful assessment made of the present condition of your teeth (really your entire mouth) will be made. He astutely offers alternative approaches to any given dental situation, and you would trust his advice precisely because he takes the time to hear your dental history from you, the client, as well as by looking at your records. I have only seen Dr. Siegel twice this year, but I felt keenly heard on both occasions, and I am very confident in his guidance and suggested courses of action. The best quality he has, in my opinion, is that he doesn't rush the client into making snap decisions about anything (even when it's clear he's extremely busy). I appreciate this quality greatly---we're presently taking a reasonable "watch and see" approach to a small issue I have that I don't feel compelled to respond to right at this moment. Just knowing that it's on both his and Barbara's radars, though, makes me feel much more confident in being able to take my time with the matter--I trust them and feel like I'm a true partner in my own care.Last, but never, ever least, the support staff is excellent--from the front desk receptionists and schedulers to the first receiving dental associates. The receptionists are swift and business-like, yes, but they never rude or off-putting. They all possess just the correct balance of very necessary efficiency (the office is extremely busy at all times) and warmth shown to the client. I'm really happy that I've found a dental group I'm thoroughly comfortable with after my former group stopped taking my dental insurance. I'll be staying Dentistry at 1818 Market a very long time. If you are comfortable with the pace of a very busy, Center City located dental office, and don't mind a smaller office space, I HIGHLY recommend this practice.

I can not say enough about 1818! Dr Siegel is wonderful - kind and gentle and skilled. The office staff is lovely. Yesterday a beautiful assistant named Nicky made a terrible day turn around by her kindness and care. Thank you Nicky and the entire staff of 1818.

The office is conveniently located. Staff are always personable. Barbara, one of the hygienists, is phenomenal. They're highly communicative, sending reminders for appointments by email and text. The practice was recommended by a colleague and I have since recommended it to other colleagues.

I’ve been to a lot of dentists in the past and I would have to say Denistry at 1818 Market st is very professional but also kind. I appreciate how kind the dental assistants, hygienists and dentists were. I’m not a fan of the dentist, but it was surprisingly not a bad experience because everyone was so nice. Thank you!

I’ve highly enjoyed my experience here. My dentist Barbra has been a delightful person to have as a dentist. Personable and friendly. I’m also one of those people who don’t mind going to the dentist either.

I’ve been to enough dentists that I can easily recognize a good one. Dr. Siegel is great! He communicates directly with me about my care and thoroughly answers my questions. He’s also gentle and compassionate. The front desk staff are all very professional and there’s never a long wait.

I've been going to Dr Seigel, and Dentisty at 1818 Market Street, for years. They are an awesome team and they help me keep up with my dental health.(As an added bonus, the team takes care to not pinch my lips/cheeks when they are going in with the instruments)!!!

I have been going to Dentistry at 1818 for approximately 14yrs while Dr. Leas was there with Dr. Siegel. I have had nothing but quality care from day one! I love Dr. Siegel and the fact that he really listens to the patient and gives direction and treatment plans thoroughly. Born with extreme Tori in my mouth, I would suggest that anyone with this condition visit Dr. Siegel and consider making him your dentist! Also, I love Drew, the front desk manager, my hygienist Sherry, and also Nicole and Dr. Doblin!! I’m always happy that they are all there when I go for my visits; they make me feel welcomed and at home. -Sandi H.

2022 the staff and doctors at this office are amazing! Very courteous and caring staff and very quick visit!I like the fact that I didn't have a long wait time since I often go to my appointments on my lunch break. The staff was courteous and Dr. Siegel is nice.

They are a great dentist, it took me a while after moving to Philadelphia to find a dentist I liked, but Dr. Siegel, the hygienists, and the front desk are all great. The only down side is they are difficult to schedule with, I suppose due to high demand (almost all hygienist slots are filled 6 months out), but otherwise I have been very happy with them. I have a complicated insurance policy, and the front was very helpful in sorting through it and figuring it all out when I started coming here years ago.

The day of my first visit, I got very lucky because a slot opened up for a cleaning, and Dr. Siegel was kind enough to fit me in early. Barbara then did a fantastic job cleaning my teeth and advising me on how to maintain them going forward. I definitely recommend the practice!

Dr. Siegel and Shari are the best! Ive been with practice since Dr Leas was there. Shari does beyond superior and excellent cleaning! When I raised certain concerns, Dr. Siegel addressed it immediately and did it professionally. He really does care for his patients! The front desk team are extremely friendly and the place is clean.

Love this place! Always friendly and efficient! Dr. Siegal is caring and thoughtful, always taking the time to sit down and explain anything needed as well. Barbara Walters is by far the best hygienist I’ve even been to as well!! She is thorough and has been the only one to be able to get my teeth plaque free in the trouble areas AND without feeling likes extracting my teeth with it. Very happy to be going here and would definitely recommend!

After being in Philly for 9 years with the same dentist who I did not care for very much... I wanted to make a change to a new dentist. I honestly wish I found them about 9 years earlier. Excellent staff across the board from front office - hygienists - Dr Siegel... entire team is terrific.

Been visiting this office for--can it be?--more than 20 years. The team here is so professional, talented, and kind that I have continued to go here even though I have long since moved to the suburbs. It's not convenient to slog back into the city for my appointments--but THAT'S how good Dr. Leas, Dr. Siegel, Shari, and the whole staff are.

Tara Perkins

Today was my first visit to this practice. They were great about covid precautions and I felt very safe. My hygienist was Shari and she was recommended to me by a friend and lived up to my high expectations. I managed a dental practice for almost 20 years so I know a good hygienist and well run office when I see one. I immediately texted my local family members and told them to schedule appointments with Shari. My only reservation is if I speak too highly of her it’ll be harder for me to get a future appointment, but she is deserving of the praise so I’ll spread the word.

Ray Lang

Fantastic, friendly, and professional staff. I seldom wait more than a couple minutes for my appointment. COVID-19 protocols are solid, as they use masks and face shield. They also upgraded to a tooth-polishing device that doesn't aerosolize saliva. My partner's dentist did not make such an upgrade, thus she was unable to get her teeth polished during the pandemic. I also find that their check-in and check-out processes, as well as their reminder/notification systems are particularly efficient compared to those of other dental offices I've frequented.

Dr. Doblin along with the staff (Drew & Nicole) were AMAZING! I went for gum contouring and Dr. Doblin explained everything and made sure I was comfortable during the procedure. He even followed up with me to see how I was doing after. My wedding is coming up soon and because he knew that he was able to put on the schedule quick, Drew who handles his book was able to put in fast when someone cancelled. I was even able to come in for a touch up. I'm now confident with my smile and I can't wait to take my wedding photos!Thank you

I am extremely happy with the service I receive at Dentistry at 1818 Market Street. The professionalism and friendliness of the entire team is outstanding! My hygienist Danielle was very nice, did a great job cleaning my teeth and is very informative. Dr. Siegel does a very thorough exam and is always willing to answer my questions. Dr. Doblin did 2 implant surgeries and both were painless. Both Dr. Doblin and his assistant Nicki made me feel very comfortable. I was impressed with how important it was to them that I was comfortable during the process. Thank you to the entire top notch staff at Dentistry at 1818 Market Street for always showcasing excellent care to my dental needs!

02:45 20 Aug 20
This is only me second cleaning with this office, but this is the most relaxed I’ve ever felt at any dentist office. They found great solutions for keeping patients socially distanced while still being efficient. My hygienist was very compliantly about my oral hygiene (i maybe an adult, but a “great job!” always feels good) and explained everything she was doing as it was happening. And they were even able to set up a second appointment to fix a filling before my insurance runs.
Alison Levy
23:44 18 Aug 20
Everyone was exceptionally kind, safety measures were being followed, and it was as enjoyable of an experience as a visit to the dentist could possibly be. I really appreciated the transparency around cost, willingness to answer questions and measures taken to make the patient feel comfortable.

I was so impressed by this dentistry office. First of all I was able to get a quick appointment for an urgent matter. The front desk assistants are delightful and extremely nice and helpful. They are upfront about costs and they accept a wide variety of dental insurances. Dr. Siegel was kind and on point as well as his dental assistant! Wonderful experience! Highly recommended. What a wonderful environment.

Trans competent dentist. All the staff work quickly and gently, and appointments are accepted within 15 minutes of scheduling. I had 4 fillings done and it wasn't as bad as I thought (always nice). If they accept your insurance, definitely give this office a try.

12:30 08 Oct 19
Great first experience! I am a new patient. The receptionist was very sweet, all the staff is super nice. Received clear and great advice. I didn't have to wait long at all. They just had an opening while I was getting a routine check up for a teeth cleaning and asked if I wanted to get my teeth cleaned as well since it was covered by my insurance. I have been to many many dentists offices and this was probably the most pleasant.
Cindy Weng
02:05 13 Aug 19
To start I do NOT like Dentists. These guys are great. They put me at ease, explained what I needed to get done...without any pressure or litany of "things we should do". Everyone was smiling (nice smiles too), from the doc to the front desk. I'd recommend these guys if your not a "dentist fan".
