First time visiting and it was nothing like every other dentist I’ve ever been to. You want to talk about taking patient care to the next level? … Well they have won my vote!! Hands down ! No competition! Period. Everything from booking the appointments down to the check out was ultra smooth . The techs, the front desk, the team lead, and the doctors were wonderful! They weren’t able to fix my “hot tooth”, but little did I know, they were going to make a way. Booked the appointment with the surgeon for me and everything before I was even out of the chair. If I could give more than 5 stars I would. I have never met nor worked with a more friendlier, collaborative staff! Seriously… Kudos to you ladies!!!!! I’ll be back, bringing the family , friends and everyone else with me. #GameChangers

One of the most professional offices I’ve ever dealt with – in any venue! Timely reminders of appointments, excellent follow-up and record keeping, meticulously clean and organized office and FUN staff! They make me smile. Highly recommended! Thanks Dr R and staff for being so thorough and helpful! Awesome dental practice!

I had the opportunity to be a patient of both Dr. Roschella and Dr. Zinger over the past month. The first visit was to replace a filling on a front tooth that broke years ago. The second visit was due to cracking a molar on a popcorn kernel! Both doctors explained my options clearly & both injections were painless! I appreciate their conservative approach and gentle touch! They also used a special dye & camera to trace the cracks in my molar. The office is state-of-the-art and everyone from the front desk to the clinicians are kind, compassionate and excellent at what they do! The root beer flavored lip balm at the front desk was also a happy surprise at the end of my appointment! Thank you RZ Dental for another great dental experience!

Joey Rach K. 

This was my first time being a patient at RZ Dental and let me just say it won’t be my last! From the moment you walk in the atmosphere is warm and welcoming. The front desk is very friendly and helpful. Krissy was the dental assistant and she is just all around amazing! She presented me with an awesome goody bag and chatted with me about my dental concerns. Dr. Roschella’s bedside manner is like no other. She did her exam, told me the diagnosis and explained exactly what she would be doing. The procedure was very easy because for one the injection was done so gracefully, I barely felt it. During the procedure Dr. Roschella explained the procedure step by step which is great for someone who gets a little antsy in the chair. My experience at RZ was awesome, I highly recommend them to anyone who is searching for a new dental home! You won’t be disappointed. Thanks, RZ for the great experience 😊

I can’t say enough nice things about this office and the folks who work here! I was referred to this office by one of my oldest friends who just so happens to be a dental hygienist here. Upon entering the building, I was greeted by the friendly receptionist and made comfortable with coffee/water while observing the calm and welcoming waiting area. The waiting area is furnished with comfortable seating, magazines, each of the doctors framed graduation certificates, a tv with a fun slideshow, and lots of natural light. After a few minutes, another woman came out to greet me, who gave me a tour of the office and shared a brief history of the company and it’s impressive accomplishments. I was then taken around back where the dental work was performed. Let me just stop here and say that this is the cleanest, most organized, and most well maintained dental office I have ever seen! From then on, the visit was a breeze. I was nervous about getting dental work done, but my worries quickly dissipated when I met both Dr. Roschella and Dr. Zinger, who are incredible at their trade. If the countless positive reviews and stories are not enough for you, pay a visit to their office and see it for yourself! The dental work was done with such care and to my satisfaction, that it’s difficult to admit that I hadn’t come in for an appointment sooner! The staff make you feel welcome and you immediately feel like a part of their family. I was astonished after my appointment about the entire experience; front the time I walked in the door until the time I left, it all was so well orchestrated and professional. It’s no wonder this office has earned so many awards and continues to thrive. Hands down, this a 5 star office!

After years of experiencing discomfort at the hands of other dentists, I decided to try this practice. Taking baby steps, I decided to let them clean my teeth (it had been years since that was done). They used that high pitch sounding instrument to clean the teeth. In a matter of minutes I started experiencing discomfort. But these people were different than the others. Instead of making me bear with the pain, they found a solution. They used manual tools. It took a little longer but they were willing to invest the time to ensure my comfort. They are uncommonly patient and empathetic. Their patient’s comfort and satisfaction comes first. After all these years, I’ve found a great dentist!!

The RZ Dental Group is, by far, the best dental office I have ever been in. Yesterday I had my first appointment with them and I have to admit I was apprehensive. However, from the moment I walked in the door, the staff made me feel so welcomed! The dentists and staff are ALL outstanding. All were highly professional with a warm, welcoming personality!! Never in my life have I felt so comfortable in a dental office! Congrats to the doctors and staff for making such a warm, caring office! I look forward to my next visit.

Exceptional commitment to superior dentistry, professionalism, dedication combined with outstanding customer service and quality which originates with founders: Drs.

My husband and I have been patients of Dr. Roschella since she went into practice in Howard County. I can’t imagine either of us going to any other dentist or dental group. Everyone is professional, extremely pleasant and the work they do is outstanding. Stephanie is an excellent hygienist… The whole team is great!

T.M.F Griggs 

RZ Dental Group should have a 10 star rating, not 5! I was given a tour of the office and introduced to the staff members before my exam with Dr. Zinger. She took the time to answer all of my questions. My hygienist was awesome too. Worth the drive from Frederick. Safety first, great attitudes, and helping within the community to promote dental health. Thank you

The Doctors, hygenists, and entire staff is phenomenal! They make you feel welcome and comfortable immediately, from the check in process, office tour, and goody bag, and they explain everything they are doing or will be doing during the visit. Hands down best experience I have ever had at the dentist, in fact, I am looking forward to my next appointment! Highly, highly recommend this practice!

I have been a patient of Dr. Zinger’s since I was seven years old and I wouldn’t want it any other way. The office is always immaculate, the staff is always kind, and they have always addressed my dental needs thoroughly. When other people say they hate going to the dentist, I recommend Roschella & Zinger because I’ve never had a bad experience.

Im not a patient, but while at Patient First for a tooth ache, this young lady named Chrissy. She did not know me but was concerned and recommended i come to Roschella & Zinger Dental. Unfortunately i do not live here but im definitely going to refer my family in Maryland about you all. The fact Ms. Chrissy took time to show kindness and boast about the office shows there still good people out here. Good employee guys! Thx Chrissy!

This was my first visit and I was so pleased and this will be the Dental Service I will use in the future and have already made my next appointment. The entire staff is very professional and friendly. This is demonstrated by the fact that they listen to the patient’s concerns and serve the patient….what a novel idea!!! If you need dental care give R & Z an opportunity to serve you.

I was terrified of the dentist all my life! That fear caused serious neglect of my dental needs. Now at 70 I finally found a Dentist! I am so grateful to Roschella & Zinger dental group for putting my fears to rest. I am getting excellent care from people who genuinely want me to have a healthy smile! They truly care about their clients.

Jean B. 

12 years ago, as a new resident to the area, I was looking for a dentist. I heard about this practice, and was WOWED from the moment I walked into the door. Our entire family of five sees Dr. Roschella — she is amazing. I personally have had some complicated dental issues, and I wouldn’t trust anyone but Dr. Roschella (or one of her partners). The entire team there is awesome. You walk in the door, and you feel such a sense of warmth and professionalism. I have referred countless people to this practice. They are, in a word, outstanding.

I have been going here for over 15 years and there can’t possibly be a better dental experience than you will have at Roschella & Zinger Dental Group.

Until I found Roschella & Zinger, I rarely went to the dentist as it was always torture. But here there is no torture, from the front office staffs warmth and professionalism to the entire dental staff. I adore my hygienist whom is gentle and thorough. Dr Roschella explains everything before and as she is working on my teeth. She is not satisfied till I am. Not only does Dr. Roschella and her staff provide excellent dental care they give back to the community. It is worth the drive from Baltimore County!

Alivia S. 

I’ve had white spots on my teeth for awhile and wanted to get them remove. My regular dentist said there was no way to get them removed so I couldn’t get my teeth whitened. My aunt Kathy and Dr. Roschella are related, so that’s how I got introduced to her. The experience was great and the people who worked on me were very kind and caring through the whole process. I’m very happy with my results

Jun 12, 2018

Jill P. 

Hands down, the BEST dental office! My cleaning with Stephanie was fantastic! I needed a small filling and Dr. Zinger was able to do it same day and she even took me to lunch afterwards! What other dentist does that?? Love all the awesome ladies at RZ Dental ❤️!

Jun 19, 2018

Amy H. 

Drs. Roschella, Zinger, and Brown have taken great care of my family’s dental needs for years. They offer above-and-beyond comforts, outstanding hygienists and staff, and a clean and modern office. These dentists care about their community, too — they donate tens of thousands of dollars in dental services at their annual Dentistry from the Heart event. This is THE place to take your children, too. We adore this practice!

Jun 16, 2018

Ashley H. 

I absolutely love this dentist! The staff is so friendly, the hygienist and dentist tell you everything they are doing so you know how your appointment is going while you’re sitting there. And it’s the cleanest office with a very welcoming feel. My anxiety is definitely gone when I’m here

I have been a patient of Dr. Zinger (and also Dr. Roschella) for — gosh — over 10 years now. And they have treated me like family, been honest with me about the state I had let my teeth get into and what was best done about it. The whole staff treat me like family and want the best for me (and my family), not just my teeth! I wouldn’t go anywhere else!

I have been a patient for 23yrs and have always had a positive experience with everyone through the years. I recently moved out of state and traveled back for my routine 6 month appointment. I cannot say enough good things about this practice. Dr. Zinger is who I primarily see and she is the best. Everyone in the office treats you like family which puts me at ease. I would like to thank you all for taking such good care of me throughout the years.

Michael M. 

I have been going to the dentist, a dentist, for as long as I have had teeth – which has been a long time, thus far. In all that time, with all those various dentists, the Roschella & Zinger Dental Group (RZDG) has them ALL beat, by a margin so large 2nd place is not even in the same league. I am not speaking about one or two good employees, and you have to take your chances when you make an appointment. The WHOLE staff at RZDG is AWESOME! In this day & age, when it seems that everything around us is slipping, getting shoddy, offering poor customer service is the new norm – NONE of that is apparent here! If you have teeth, I STRONGLY recommend you come here. Bring your friends, bring your family, bring anyone you care about – because THIS is the BEST dental practice I have EVER been to. Period. This is not hyperbole, just the pure, unvarnished truth. If you don’t come here, please don’t waste my time by complaining to me about you not liking to go to the dentist. Me personally? There is no better place to take your teeth!

Apr 11, 2018

Great visit every time. Always on time and explain all options.

Roschella and Zinger Dental Group is the best, everyone in the office makes you feel comfortable, they are friendly and they are always on schedule. I have never had to wait more than a few minutes. I have been going there for many years and i will continue to.

My name is Bryant. I came to this practice as a new patient coming from Pasadena… Reading all the reviews and hearing all about this great practice I can only confirm that everyone was right!! The office is very clean, up to date and was most important I was acknowledged when I walked in by the receptionist with a smile. Everyone I came across was very friendly. I saw Doctor Roschella who gave me a thorough exam. She fixed my front tooth which was broke. I was very pleased with the work. I couldn’t even tell which tooth I chipped because the color matched very well!!!! Thank you RZ DENTAL for the amazing experience from beginning to end

Lisa Scarbath 

My family has been going to RZ Dental Group for twenty years! As a child, I had several bad experiences at the dentist, but the staff and dentists at RZ have totally changed my opinion. I no longer dread having my teeth cleaned and happily go every six months knowing that I will not have to wait, will be greeted in a friendly manner, will have a professionally skilled and kind hygienist, will not be “sold” on unnecessary procedures and checked and treated by the best dentists. My three children have been going to RZ since they cut teeth, were lovingly taught how to care for their teeth and praised for doing so, but never scolded for falling short. They never fear going to the dentist. What a relief!! We appreciate the feeling that everyone at RZ Dental values us as clients and we HIGHLY recommend them to everyone we can.

Wanted to give six stars to Dr. Zinger and staff. Not possible. Pity.
