Round Valley Dentistry

A high-quality, family-oriented dental office offering a full range of dental services to the Hunterdon County community

Operating as usual


While we were closed, we did a bit of "Beautification"! We hope you enjoy the new landscaping!

We also added some Ozone systems to clean the office and the air-ducts.
(clean on the inside, beautiful on the outside!)

[05/30/20]   June 1st is a big day for Round Valley Dentistry!

We are opening for our regular hours.

We appreciate your patience during these difficult times.
Our longtime patients will notice some differences though. We will be limiting some of our treatment options for the next few weeks until The State of NJ gives us the "all-clear" to resume Full-operations. Please bear with us a much as possible. We ask that all patients wear face mask when arriving at the office. We will then screen each patient and take a temperature reading for you. This is in the interest of everyone's safety. As we move further into June, expect operations to normalize.
Our Team at Round Valley Dentistry once again thanks all of you for your understanding and your support!

[05/07/20]   To our Patients:
We would like to update you with the latest on the COVID-19 Situation and how our office is adapting.

As of now, we are seeing Emergency Patients, in-office, on a regular basis.

Our hours have been limited.
They are now Mon-Wed-Friday, from 9AM to noon.

During these times, we are taking all recommended precautions. The waiting area, common areas, and treatment rooms are all being disinfected to the highest standard possible. Because of these precautions, our pace is a bit slower than usual, and we thank you for your patience.
Our services at this time, by NJ State Executive order, must be limited to Emergency patients only. Be reminded that "Emergency" patients are typically going to have dental pain, unstable dental situations, infections, or a combination of those. All offices in NJ are operating under these same rules.
Some situations can be handled via "TeleDentistry", where we can assist a patient via Telephone call. This does have limitations, but for many infections or severely broken teeth, we can coordinate with local Specialists to get you seen and treated. For Emergencies that are within the scope of our Office, we will be scheduling patients within those times listed above.
We are awaiting a timeline from the Governor, as to when we can resume full business operations, until then, stay safe and healthy!
Thank you for your trust in our Team,
Dr. Mielo & Staff

[03/18/20]   To our Patients:
During the COVID-19 Emergency, we will be open for limited hours. These appointment must be reserved for Dental Emergencies only, as per NJ State Guidelines.

We will be adding additional hours after the Emergency declaration ends, in an effort to accommodate any regularly scheduled appointments that we were forced to cancel. For now, please be patient while we await a clearer picture on how this situation will resolve.

Thank you for your understanding and patience. Stay safe and healthy.

Dr. Mielo, Dr. Steele and the Round Valley Dentistry Team


At Round Valley Dentistry, we continue to provide the best technology for our patients!
We have just upgraded our Digital Scanning Technology to include the new iTero 2 Scanner.
This machine can now scan directly to Invisalign Orthodontic Program, as well as creating an unmatched accuracy in Crown, Bridge, Veneer and Implant restorations. In most cases this technology eliminates the need for messy and uncomfortable impressions!

[10/03/19]   To all of our patients:

We apologize for the inconvenience but our office will be closed for Thursday OCT3 and Friday OCT4 due to a plumbing issue.

Thank you, and have a Great Weekend!


Patients often ask us, "What does Dr. Mielo do in the Navy?"

The best way to answer is to show what he accomplished during his "annual training" which he completed in the first 2 weeks of June.
For this mission, Dr. Mielo was located at a Marine Corps training facility in the deserts of California.
Primarily, Dr. Mielo received Tactical Combat Corpsman training, during which he worked to "save the life" of a Robot/Simulated Casualty while in a combat scenario. (as seen in Pics below). These Robotic simulators can actually speak to you and provide as real an experience as is possible in a training environment. We are happy to report that Dr. Mielo's Simulated casualty survived!
The remainder of the training mission involved setting up a temporary dental clinic in an "austere environment", and helping as many Marines as possible with their dental problems. All in all, a great experience with some truly fantastic people!


Congratulations to Dr. Mielo for being named to the list of New Jersey's Top Dentists!

Dr. Mielo and Dr. Steele are working hard to make sure that your experience at Round Valley Dentistry is the best that it can be!

New technology is very important to all of us at Round Valley Dentistry!
We have recently added the latest in 3-D Computerized Scanning technology from 3M.
What this means is more accurate models of teeth and gums. With this advanced device, we can produce the finest Crowns, Dentures, Nightguards. We can even use this technique to take the models for Invisalign clear Braces!


Arctic Care 2017- Round Valley Dentistry will be back to it's full week schedule now that Dr. Mielo is back from Alaska!

Dr. Mielo was serving with the military as part of a joint-services, international team. This group was tasked with helping Underserved Americans in Alaska and providing them with Dental, Medical, and Veterinary Care at no cost!
The mission was a wonderful success and over a thousand patients were helped. Dr. Mielo was mainly in the area of Port Lions, and was very grateful for the hospitality of the local residents.


Tropic Care 2016:
One of the less well-known functions of our service men and women are the frequent Humanitarian Missions that they perform. This year, we are gearing up to perform a joint medical/dental mission to help the under-served in Kauai. This will be a 2+ week mission where several thousand Hawaiians will receive cost-free care! 28 Navy, Air Force, and Army Dentists will be working hard to contribute. This past week's conference was the last step in making the June/July mission a success!!


We just have a quick word to say concerning Counterfeit and "Grey Market" purchases of Whitening systems and medications. We are seeing more and more patients buying prescription items from vendors such as eBay and Amazon. We do not recommend purchasing items by this route. The small amount of money saved is not worth the potential risks! Please see the attached letter from one of the leaders in Tooth whitening technology:


Round Valley Dentistry would like to welcome our newest member, Dr. David Steele!
We are very proud that you have joined our team. Dr. Steele comes to us after having practiced in the Kenilworth area for over 20 years. He has been voted as a "Top Dentist" in NJ, and brings a refreshing and caring personality to our Team. Dr. Steele is leading our office into expanded hours, and includes Saturday appointments! 07/06/2015

Dr. John F. Mielo - Top Dentist in NJ

I am feeling proud to have spent the last 14 days with some of the finest Marines and Sailors! A truly wonderful bunch of people. During those 2 weeks, we treated over 400 Marines for various Dental Issues. We created quite a few smiling Marines!!

Our unit dealt with 100+ Degree heat, and high humidity for the duration of our training. I am so proud of all the members for carrying on without complaint and performing so admirably.

Our unit's second mission was to achieve the "Fleet Marine Force" certification. (FMF) This is a rigorous training regimen, where we pass the Physical Fitness standards that all Marines are required to pass, as well as learning Land Navigation techniques, Martial Arts, and other useful lessons. The Marine Base Commander said he had never seen such a motivated group. (this is a fantastic compliment, especially considering that we were all Dentists!)

After experiencing these conditions for just 2 weeks, I can only say that my admiration for our service men and women has increased even more. So many of our soldiers live this life for a year at a time. God bless and protect them.

[06/27/15]   Round Valley Dentistry will be back to our usual hours on Monday June 29th! Thank you for your patience! 05/11/2015

A great 2 Week Exercise with the USMC and Navy! Dr. Mielo, as part of the 4th Dental Battalion, assisted in aiding over 400 Marines with their dental needs. Along with LCDR Hood and a wonderful team of Corpsmen, we left behind a group of thankful and healthier Marines! The Teamwork that we observed, in both the Navy Corp and the Marine Corp was truly humbling. Hopefully, we will be back next year to FT AP HILL, VA!

[07/30/12]   I've just returned from my 2 week deployment with the Navy Reserves at Camp Lejeune in North Carolina! Business hours will be back to the normal times.
What a wonderful experience spending time with the Marines and other Navy personnel. Truly admirable people who sacrifice so much for their Country.
I would like to thank all of them for their service and the great welcome they showed me!
