Ashley M. from Carteret, NJ (Source: Yelp)


I had an emergency that needed immediate attention. Since my first call, they knew what to do & how to go about everything concerning my situation. (Especially DR.J) I called on Monday and i was seen two days later. I was very happy. I Came in to a very controlled environment which also made me happy and comfortable. I was seen by DR. Gent. He was very nice and told me everything he was doing & going to do. He always made sure that i was okay, especially if i was in pain. He was patient and made sure everything he was doing was correctly. He took his time, which made me very satisfied that he did a good job. Since i left i feel no pain.

I just recently started going here in the summer. I’m going to keep them as my regular dentist. Their staff is friendly and informative. The place is not only clean but soothing. Today I was very nervous for my 4 wisdom tooth extraction and Dr. Lenny Nashtatik took care of me quickly and efficiently while also helping me feel comfortable by making some jokes. He really knows how to feel the room for what a patient needs. Overall, I highly recommend this place for your dental needs, especially if you are in the Washington Heights/Inwood area.

If you’re looking for caring doctors, that are also perfectionist and take pride in their work this is the right place for you. From the moment you enter, you are greeted by the front desk staff that are both sweet & Informative. The services I have received have been the following cleanings, removal of old cavities to new beautiful white ones that match my teeth & I have had contouring of my gums (aka tooth lengthening). I was terrified at first to have the gum contouring,but the specialist that did my procedure was confident, and reassuring. The procedure was painless,and the results have been amazing. The one downside I had was that I misunderstood the pricing for my Invisalign, so I decided that I would continued receiving my cleanings twice a year at Cascada, but that I would have my Invisalign done somewhere else. I went to a great doctor on the Eastside,and although he was a good doctor in a very high end location he wasn’t Dr Y, and the proof is in my Invisalign results. Although I went somewhere else, and was extremely unhappy with my results- rather than Dr Y and Dr Joseph making me feel horrible about my choice of going somewhere else… they have been nothing but understanding, kind and patient while working with me. They simply want me to have the smile that I desire & deserve. If you go to their social media page on Instagram you will see that they have been blessed with having many clients, and some of those clients are well known celebrities, and in my opinion they treat all their patients the same, and we all receive top notch services.

I have been coming to Cascada Dental Spa for a little over 4 years. It all started with a toothache around 2015/2016 after I had neglected going to the dentist for a few years. Dr. Josephs removed all 4 of my wisdom teeth, Dr. Y handled my Invisalign treatment plan, lip fillers, and I lost count of how many cavities I have had filled by the other remarkable dentists at their practice. *While going to the dentist isn’t the most fun, I’m happy to report that they always numb me and I have never felt any pain during my many procedures. 🙂 The practice is super clean and the aesthetic is sleek and modern. I can’t recommend Cascada Dental Spa enough. Everyone is so kind – from the staff at the front desk to the dental assistants and hygienists.

My experience at cascada dental has been beyond amazing!!! My complex treatment consisted of 2 periodontal surgeries to get my gums healthy again, a molar extraction, a crown, fillings and now i am on my first tray of Invisalign aligners! The staff is so great and i feel assured that my treatment plan will exude amazing results, thanks cascada dental!!

Jae D. from Bronx, Bronx, NY (Source: Yelp)


After seeing reviews on Yelp, and going to 6 consultants.. I made an appointment at Cascada Dental Spa.. from the first appointment I was impressed.. The office was spotless, modern, staff is friendly and Dr. Y is very knowledgeable.. Dr. Y was familiar with my past orthodontist experience, and was able to transfer my Invisalign case and fix my #1 problem.. which was a discolored tooth.. and i needed internal bleaching..on my front tooth..I cannot stop smiling.. something I have not done in 5 years.. thank you Dr. Y, for not, replacing my front tooth with a crown or a cap (as recommended by those other dentists) you’re the best

I started coming here after a friend recommended and it’s been great. I always feel comfortable during procedures and never feel pressured for anything unnecessary without proper information. I also appreciate how thorough they are in working with my insurance ahead of anything. After years of discomfort even with other dentists, I’m finally pain free for good! Francia, thanks for the guidance and keeping me honest & on top of my dental care. Stephanie, my hygienist, thanks for the clean up, I almost fell sleep twice on you.

I’m usually petrified of the dentist. But Donovan and Julissa his assistant made this experience so much better for me. They helped me overcome my fears and we’re so gentle and patient with me. They are also extremely good with time. I got two fillings done in like 30min-45min. And with them I have never waited more than 5 min in the waiting room. I have seen them 3 times for fillings. Donovan and Julissa are the best team!

Tyeisha G. from Bronx, NY (Source: Yelp)


I’ve been coming to this dentist for the past 3 years and I’ve watched the office expand in staff and clients. I used to be afraid to come to the dentist until I started to come here. My personal dentist is Dr. Y but all of the staff there from the front desk to the hygienist, everyone is ABSOLUTELY AMAZING and I now have all of my family and friends coming to this great dentist they make you feel so comfortable and confident with your smile when your visit is over and I definitely recommend this dentist to everyone!

Melvin M. from Washington, DC (Source: Yelp)


Absolutely, Cascada is the best dental experience I have had in my life.  It’s really gold find!  The owners of the company are both Ivy League graduates and their signature of excellence is on every part of the patient’s journey through treatment…from registration, to initial visit, to services of care provided, and follow-up.  In addition, their patient centered approach and community driven vision really stands out so clearly and you get that they care about more than just the patient’s dental health, but their whole being.  The staff is super friendly, competent and efficient…all with a very short wait time to see the doctor.  They have cutting edge technology that thoroughly impressed me – I didn’t even know that the dental field had advanced so much!! Lol.  It really is a SPA for your teeth! I highly recommend Cascada Dental spa

Arletty D. from Yonkers, NY (Source: Yelp)


They had me at hello, from reception taking the time out to coordinate appointments for my daughter and I, to the dental hygienist who made the X-rays comfortanble to the dental assistant who did my cleaning, and finally the dentist who performed my extraction I was always in good hands.  Gentle and smooth every step of the way.  This office exercises real  teamwork with customer service being the number 1 priority.

Gio A. from Jersey City, NJ (Source: Yelp)


This is the most amazing dental experience I have ever had! The facilities here are state-of-the-art with all the new technology you expect in Midtown NYC but located Uptown in Washington Heights…And to my surprise, they even take Medicaid and most insurances. The Doctor, Dr Yaraghi-Josephs was extremely knowledgeable and gentle. I usually hate going to the dentist but after this experience I am looking forward to my regular check ups. Love this place! 

Lisa K. from New York, NY (Source: Yelp)


This was my first time to the office. I was looking for a dentist in my neighborhood and I came based on the positive on-line reviews. Usually I only use word of mouth recommendations from friends but as I am quite new to the area that wasn’t possible. The facility is beautiful – clean, new and professional. The receptionist was friendly and efficient. My appointment was on time. And Dr. Kim, my assigned dentist was great! She has an excellent manner – approachable but professional. My check-up and cleaning went perfectly. I definitely will make this my regular dentist and I recommend them to anyone else.

Brenda H. from New York, NY (Source: Yelp)


My experiences at Cascada Dental Spa have been great. The service you get in this place does not compare to any other you’ll get in the area. So far I’ve had X-rays, a cleaning and fillings (which were mercury-free). It was painless and the dentist was very gentle. I also had the zoom whitening! I feel like a new person. It definitely works and they make sure you’re happy with the results. My mom didn’t have dental coverage and I was glad to see they have affordable options for people in that situation. The office is clean and beautiful, definitely spa-like and the staff was very kind and professional. Keep up the good work!

Jerome J. from Upper West Side, Manhattan, NY (Source: Yelp)


I had an infection following a root canal procedure I had done at another dentist. The infection got so bad and painful, I could barely sleep at night and had difficulty doing basic daily activities. Given what’s happening now with COVID-19, I understandably had difficulty finding a provider who was open and could see me. The Cascada Dental Spa team welcomed me with open arms and was able to remove the tooth in question. This team deserves mad props for doing this work and being so professional. Looking forward for retuning again in the future!

This place is amazing, I am so happy I discovered this dental office! Recently I started slacking off coming to the dentist due to some bad experiences but Cascada took really great care of me. The front desk staff are phenomenal and friendly and always greet you with a smile! I had all my wisdom teeth removed with Dr. J. I had high anxiety going in there with the procedure but he hid such a good job and has really great bedside manner. He explained everything he was doing and really gentle. The whole process took only a hour and the healing went well with minimal swelling. All the dentists within the good are professional and do a great job to make sure your concerns are addressed. The wait times are minimal and there office is clean and spacious! I like that they are also open on the weekends and close at 6. Even if your primary dentist is not available there’s always someone who can see you! I recently started Invisalign which I was thinking about for a while, initially I did have some doubts but between Dr. J, his wife, and Dr. Tiffany they answered my bucket load of questions about the process and Dr. J made sure they were delivered on time due to some time constraints I have. The dental hygienist’s and techs are also great! I rate this place ten stars!!! You really don’t have to look any further, best place in the area!

Cascada is a top notch facility, I have been coming here for years. The staff is awesome a huge thank you to Patricia for all you have done you are a true asset to Dr.Y and Cascada, now onto Dr Shin he is brilliant, a true artist when it comes to your dental needs. He loves his work and the attention to detail goes far beyond to see that you’re satisfied and it shows when you have the perfect smile, when you first meet Dr Shin for a consultation depending on your dental needs he will give you many choices, if any of your teeth don’t need to be serviced he will tell you he’s a very honest person, Cascada follows all Covid 19 protocols has state of the art equipment and the newest techniques available, if you are afraid of the dentist like I am, don’t worry he and his staff (Jusli) will make you feel relaxed and comfortable. The personal attention he gives his patients by personally calling or texting them is something you don’t see anymore. Thank you Jusli and Dr Shin you are amazing, see you soon

I have been to this location few times for emergencies and I always had a great experience. I have a regular dentist in my University but they don’t have flexible hours so I saw two dentists here so far on three different occasions. I was able to get same day appointments and was seen quickly. The location is clean and very organized. On top of that, the doctors here are extremely professional and never try to push any treatments or procedures. I recently had an urgent issue during the lockdown and Dr. Joseph got back to me within few minutes and offered a thorough tele consultation.  I’ll recommend this to anyone looking for a professional and honest opinion.

Jacqueline Y. from Mount Sinai, NY (Source: Yelp)


I’ve been going to Cascada Dental Spa for years and I couldn’t be happier. The doctors and staff are so nice, professional and patient! You never have to wait more than 10 minutes to be seen and each doctor takes the time to address all of your concerns and needs. I highly recommend coming to this practice! You won’t be disappointed!

Vi V. from Brooklyn, Brooklyn, NY (Source: Yelp)


The manager called me after I gave negative feedback because of my concerns. After the call, I realized that my concerns were groundless. The manager (doctor, I dunno) explained to me how they treat every customer, cleaning procedures and so on. It was very nice of him. PS. Did surgery with the doctor *forgot his name* and the surgery was excellent. The assistant was ok, could be more attentive. 5* for the doctor, good job. Keep it up!

I have been a patient for over 6 years and they have treated me like family since the first appointment. The staff is always professional and courteous and the Doctors make it clear they care about their patients. I have referred many of my family, friends and coworkers and they all love the treatment here as well. My dental hygenist Rosa is the best in the business and has worked with me the entire time I’ve been coming here. I highly recommend this dental spa.

The best dental office experience I’ve ever had!! Marci was great! Her personable, and warm disposition along with gentle yet thorough techniques are top notch. I was never big on going to the dentist, so I would avoid then until I absolutely had to go, but Marci has changed that for me. I’m determined to make my regular visits to Cascada Dental Spa from now on!!

Natasha G. from Washington Heights, Manhattan, NY (Source: Yelp)


Casacada is just plain awesome. From their customer service to entire staff.  I had a billing concern and Doctor Joseph (the owner) personally sat down with me to go over my concern and got the problem resolved. I can honestly say that they care for their patients. Couldn’t be more happy to pick this office as my number 1 choice. Trust me, go to Cascada! You would not regret it. Thank you Cascada & staff

Donya M. from Manhattan, New York, NY (Source: Yelp)


Best dental office!!! Last time I was there getting Zoom Whitening, I was checked on multiple times throughout the whole process to make sure I was doing okay and they stopped the cleaning as soon as my teeth felt a little sensitive. The staff is very friendly and answers all questions and concerns truthfully. I always get a reminder when I’m due for a cleaning which is extremely helpful and appointments are very easy to make. I am so happy with my results every time I leave their office. I highly recommend Cascada Dental Spa!

Alioune S. from Manhattan, New York, NY (Source: Yelp)


Best dental office I’ve been to in the 22 year of me living. All of the people are very nice, and inform me of what problems I have and the best solutions. They give out free cold water in customized water bottles (super cool). Shout out to my hygienist JENNIFER for being very helpful and friendly, an MAGGIE for making sure I make my appointments with force . Coffee lovers also get a free mug for being part of them, and just to have it be mentioned they have a very soothing waterfall in the waiting area. I encourage all in the area and beyond to drop in. #Blackfridayinvisalignsale #$500off

Jae D. from Manhattan, New York, NY (Source: Yelp)


I have been to Cascada twice now, and “Dental Spa” does not even begin to describe how fantastic the service is at this place.  Never has a dental provider treated me with so much concern, constantly checking-in “are you okay” from every member of the team, is so surprising and refreshing; it helps minimize the horrible fear of the dental procedures.  I went in for a simple cleaning, and ended up needing a deep-cleaning/scaling; with fear, I returned, and it was a success and virtually painless.  I highly recommend this place, for its service/cleanliness/ accommodating attitude, and their willingness to teach their patients about bettering their oral health.

This place is incredible. The staff are always friendly, it is exquisitely clean, and the doctors always take their time with you, explain everything and are so knowledgeable. I’ve never been to a dentist who had such great technology that could track my progress and treatments. Dr Josephs and Dr Nehleber are absolutely incredible at what they do, super knowledgeable and so so gentle to the touch. I keep making the trek from Brooklyn just to come to this place because they are that good!!!

Draye G. from Manhattan, NY (Source: Yelp)


Well I don’t even know how to start talking about this place it’s been an amazing experience coming I must say I had my doubts but I’m more than satisfied that they prove me wrong the staff is 5 stars and the dentist it’s just out of this world and having a one on one with the owner of such of distinct place it makes you feel more then safe him and his wife are just even more reason to come and get any dental repair here it shows their commitment to give and amazing service office super cozy and clean try it out you won’t regret it.

Henry R. from Bronx, NY (Source: Yelp)


The staff at cascada are very professional, considerate and kind for a long time I’ve had low self-esteem and felt ashamed for not going to the dentist do to my phobia but after I got past it and was ready I couldn’t because by this time I was humiliated but never the less I summoned the courage and made my appointment the experience was more than I could’ve expected everyone was very understanding and helped me get through it now this is my only dental clinic and I’m well on my way to having a million dollar smile 🙂

Jackie C. from New York, NY (Source: Yelp)


Absolutely LOVED this dentist. The offices are very nice, and the staff are great, but I was more impressed with the hygienist (although I forgot her name) and the dentist (Dr. Yaraghi-Joseph) than anything else. They were both super nice, answered all my questions, and very thorough. Considering the cost of health coverage these days, I wish all doctors/facilities showed this level of service. Looking forward to my next visit.

I am delighted with the service I received today at Cascada Dental Spa. The quality of customer service provided by the receptionists during the registration process is excellent. They explained in detail the services offered by the Dental Spa, and the health insurance verification process and the HIPAA form were highly explained and completed with professionalism. The dental assistant and the Hygienist were very kind, polite, and professional during the interview and the dental exam. The entire process during the dental care procedure and X-Rays are very safe and comfortable. The Hygienist was very kind all the time, explaining to me in detail how to prevent cavities and other mouth and dental care conditions, she did an excellent job. They make you feel safe and comfortable during the examination and the procedures!. The Spa possesses a friendly and professional environment that is regulated by the health policy and norms, and the staff behavior follows ethics and principles of care. Finally, I met the Dental Care provider, who took care of me and made sure that the service is provided with the high standards of care. I will undoubtedly remain to be a patient of Cascada Dental Spa. Thanks for the service and the professionalism, the kindness and the confidentiality and the efficacy. I am very happy for having received a high qualified service. kind regards, Luigy Alba.

Gorgeous Practice and love that they take care of New York’s Finest and some of us that are also in the field. Dr. Joseph is super sweet and bed side manner is great. Very down to Earth. Love that they are up to speed on the Social Networks being as that is how I learned about them .Very well kept and the assistant was great at informing me what was to be done and making me comfortable.Great staff great experience Highly Recommend!

I had not been to the dentist in almost 10 years. I looked around for a dentistry and decided to give Cascada a shot, given the close proximity to my residence. Before I even show up I receive multiple, well spaced out notifications informing me of my appointment. I walk in, front area is clean enough, staff is friendly, I am provided with my own hand sanitizer and proper precautions appear to be in place to protect me from the pandemic. I’m called in, my temperature is checked, I’m asked to wash my hands, they sit me down on a sterilized protected chair and I’m gritting my teeth out of fear that I’m about to be told my teeth need to come out. In comes Stephanie, the dental hygienist and these 5 stars are all for her. She carefully explains procedures needed, reviews my x-rays in detail, provides me with a cost breakout of what she believe I need and begins to clean my teeth. I feel absolutely no pain, her hands steady enough to perform the most difficult of procedures and her sense of humor and approachability keeps me calm and smiling, as much as humanly possible given the circumstances. I was in absolute awe of how smooth the procedures with her have been so far. So much so, that if anyone ever asks me about recommendations for a dentistry, I would send them straight to Stephanie at Cascada without an ounce of regret. FYI, I got to keep all my teeth.
