Dr Pham-Nguyen is great! She's very patient with me and my questions, and super gentle, even during a tough wisdom tooth extraction. Care is prompt and equipment seems up to date; I came in with a lot of dental anxiety and Dr Pham-Nguyen has helped me tremendously. I don't know who Dr. Siles is, but I presume they no longer work at ECO Dental.

I found Dr. Siles very professional and extremely experienced in general and cosmetic dentistry. My teeth had a bite that did not line up and they were very yellow and now my teeth look great ! I get compliments all the time. One of the best investments I made was in my teeth and working with Dr. Siles.

I have been a patient of Dr. Siles for over 40 years. It is my opinion that he provides the highest quality of both general and cosmetic dentistry available. I have always been very satisfied with the work he provides and would recommend his services to anyone in search of a quality dentist.

My name is Sylvia Craig-Hoyt and I'm 55 years old. I first saw Dr. Siles work with his lovely wife Ruth. After admiring her teeth, she suggested that I have a consultation with him. I made an appointment and he showed me some pictures of other patients that had their smiles repaired by him. I was amazed! My bottom teeth were very short and brittle from years of grinding my teeth in my sleep. I agreed to have all of my bottom teeth redone with porcelain crowns and veneers. They turned out perfect! All I could think about was getting my top teeth done as well. I wanted that more than a new car, new diamond ring, or a swimming pool in my backyard. The amount seemed to be a little more than I could possibly afford but I decided to talk with my husband about it. He said that he knew how much I wanted it and that I do so much for our family that we would find a way. So I raced back to Dr. Siles with the good news. I'm now so happy with my completely new smile. It feels to me like I have had a face lift. I look younger and can't stop smiling! Dr. Siles and his staff were awesome. His work is perfection club quality. I even recommended him to my daughter and she is just as happy as I am!

Hi my name is Tina Emmerick I started going to Dr. Siles in 2006 for a full mouth reconstruction. I suffer from Amelogenesis Imperfecta a rare disorder that doesn't allow the enamel to develop properly. It causes the teeth to be very brittle and discolored. I was very embarrassed of my teeth, and on my way to dentures at the age of 23. After researching many offices I found Dr. Siles and made an appointment for a consultation. He has been taking care of my teeth ever since. I am very thankful to have found such a great dentist, my condition is very rare, and most dentists did not know what to do with my case. Dr. Siles has been very kind through the entire process working with me when times were rough. He has given me the smile I have always wanted, I receive compliments on a regular basis. If you are looking for a caring, professional dentist this is the place to go.

When I was seven years old, my older sister slammed a door in face causing me to shatter my front tooth. My mother took me to my regular dentist where I had to get a root canal and a metal post along with my unappealing crown that was a combination of metal and porcelain. It was extremely noticeable and made me very self conscious of my smile. I hid my teeth and would never smile for pictures. Three years later while I was swimming in the ocean, my crown fell out and was lost in the water. I went weeks with a dull yellow temporary before having it replaced. The dentist ignored my concerns about the grey appearance and the new one was just as unappealing as the first. Finally once I was in high school and had my braces taken off, I wanted to get the crown redone and my dentist explained that I wouldn't be happy with the outcome unless I got a matching veneer on my other front tooth. So after spending thousands of dollars and drilling down a perfectly good tooth, I thought I would finally be confident. But that wasn't the case. I was still very unhappy about the appearance of my smile. It was traumatizing for me and caused me to be self conscious of my smile for over twelve years! Finally, when my veneer fell out I realized I just couldn't take it anymore and that's when my mother referred me to Joaquin Siles. I was skeptical at first because as a college student that's a lot of money for me but I saw the wonderful work he did on my mother's teeth and decided to make an appointment. I explained everything to him and he really listened to all of my concerns. He took the time to show me pictures of all the different shapes and lengths and made it a point to make sure it would be exactly what I wanted. I now have four beautiful porcelain crowns and two veneers on my upper teeth. I am finally confident with the appearance and now always have a smile on my face. He is extremely thoughtful and talented. He and his staff make it a point for you to feel comfortable and they are all so sweet. I would highly recommend him to anyone interested in cosmetic dentistry. I know it can be expensive but it was worth every penny! He is truly an artist and has changed my life with his beautiful work. I cannot thank him enough!

I went to Dr. Siles office for a simple teeth cleaning and possible whitening on my lower teeth. When Dr. Siles saw my teeth, he astonished me by letting me know that he could open my bite allowing me to possibly get veneers on the lowers, creating a much better smile and overall look. He was able to increase my bite and lengthen my lowers allowing me to finally for the first time show my lower teeth when I talk and smile. It has changed the lower shape of my jaw creating a much more youthful appearance. He was able to do what my orthodontist and former dentist were not able to do. I have been so happy with the results and now I am looking forward to doing the upper teeth as well. Not only was he a joy to work with but his entire staff worked with me to ensure that I was totally taken care of. They went above and beyond what a regular dental office would have done and I am forever a huge fan of Dr. Siles' work! He is truly a master at his craft. Thank you so much to Dr. Siles and the entire staff for your dedication and care of your patients. Sincerely, Sheila Walstead

Dr. Joaquin Siles has been my dentist for many years now. In fact, I have a bridge with four porcelain crowns, that were done in 1994 and are still in great shape. I did not have any problems at all. Dr. Siles has been a dentist for my entire family providing with multiple major restorations like crowns and implants for my husband and children. Dr. Siles has good professional manners and great skills. I would recommend him to people who are looking for a good dentist.
