Dr. Neff has been my dentist for about five years now, and I couldn’t be happier.  I am always seen on time and he is always friendly and professional.  The care I receive is exceptional, especially on the more complicated procedures I have needed, which have included replacing a crown and having a chipped tooth bonded.  I highly recommend Dr. Neff and his staff!!

Dr. Neff has been my family’s dentist for over 10 years, he is very professional and an excellent dentist.   I never wait more than a few minutes to get in a chair so appreciate that his team manages appointments as this is very important to me.   I would recommend Dr. Neff to anyone.

I had an absolutely great experience at Dr. Neff’s office. His dental assistant was so friendly during my xrays and Dr. Neff gave me such a great understanding of how our teeth work and what I have to do take care of them better. The lady’s up front who set my next appointment were amazing and helped me chose the whitening solution that was fit for me and my pocket. Absolutely loved my whole appointment.

I love these guys! The front desk staff are so attentive and organized. Doctor Neff is amazing! He really takes his time and has the best bedside manner. I finally don’t hate going to the dentist! I would definitely recommend this practice to all my friends and family. Thanks Dr. Neff!

Dr Neff is an incredibly good dentist, he is definitely a straight shooter, and he knows his stuff! His staff is friendly, courteous and professional.

Mike D. from Carlsbad, CA (Source: Yelp)


I’ve been a patient of Dr. Neff for nearly 7 years and am consistently pleased with the service and the overall experience. I’d also like to give a special shout out to Erin, one of his dental hygienists. She is so good that I schedule my checkups and cleanings around her schedule! If you are looking for a good dentist, please consider Dr. Neff – and be sure to ask for Erin too! 🙂

My Family and I have been under Dr. Neff’s care for over two years now. I had to have my wisdom teeth pulled recently which was a great concern. What I experienced during the procedure was exactly as what Dr, Neff has described, pain less and quickly done. I was also pleased to see a big cut in the cost since I didn’t have this done by a specialist. Over all it’s a great office with knowledgeable staff and would recommend them to any one who’s afraid of going to dentist 🙂

I don’t think I have ever found a dentist I left feeling satisfied with. But the hunt is over! I appreciate the time and the care he took to explain so much to me. I appreciate the knowledge I now have! Feeling optimistic and better than ever. Thank you again 🙂

Dr. Neff and the Los Coches staff are my heros. Going to the dentist, let alone getting your wisdom tooth pulled is never something I would look forward to, but Dr. Neff and his incredible staff at Los Coches dentistry made it a pleasurable experience. They treated me like a friend, not a customer. Everyone was so kind and attentive to all my needs. Dr. Neff did an amazing job of explaining everything and making sure I was comfortable and at ease before he started. He was so good that I didn’t even realize my tooth had been pulled!!! Now that’s skill. I would highly recommend Los Coches Dentistry.

It has been a long time since I have been to the Dentist. I have had bad experiences in the Dental chair  in the past as a child  that gave me a Dental  fobia..  I have heard  what a wonderful  Dentist Dr. Mudgett is. I decided to make an appointment with him. I had a great experience with Dr. Mudgett.  He has a  great personality . He is gentle.. He really made me feel comfortable……His staff is awesome!!  I highly reccommend this office for all ages!!

Casey M. from Flat Rock, NC (Source: Yelp)


I’ve had a fear of dentists for many years…(all the way back to childhood) …hadn’t been to a dentist in a while soooo time to hit the pavement and find one.I was first impressed by the staff, friendly and courteous. Then I met Dr.Mudgett his firm hand shake and pleasant smile was reassuring but I was still nervous. To make this short I had several filling done and have to go back for a crown… NO white knuckles grabbing the chair ………NO PAIN…NO discomfort…teeth look good..looking forward to getting the crown done and will be back for the regular checkups…p.s.never wrote a review for a Dr. before …that impressed :o)

Finest Dentist I’ve used. Why, Bill is very patient and spends the time to explain things he’s doing. Dr. Neff actually assisted with my teeth cleaning as well. I’ve never seen a Dentist do that! Very friendly staff and clean modern office.

Paulette K. from San Diego, CA (Source: Yelp)


I don’t hate going to the dentist anymore. Dr. Neff has gentle hands and is a total perfectionist. His front office team are the best- super sweet and extremely organized and stay on top of me for my appointments. The place is technologically advanced all the gadgets, tvs on the ceilings etc. My smile never looked better. Dr Neff even fixed a front filing perfectly that 4 dentists couldn’t get right. My entire family- husband, sister, brother they all go to this office and so should you and your family!

Wow!! Best Dental Exam and cleaning I have ever had…and everything was clearly explained. From front office to back….everyone was very nice, friendly, and professional. Up to date dental equipment and Dr. Neff was honest with the work I needed done. And love that they are open on some Saturdays!

Mark S. from Carlsbad, CA (Source: Yelp)


Went in for a first time visit to get fitted for a custom snore guard. Next thing you know, I was so impressed with Dr Neff and his staff that we are switching our family of five from one dentist to this office! Dr Neff took the time to fully explain my questions and I didn’t feel rushed.

Dr. Neff was professional and personable. He put me at ease with my concerns about my teeth. I thought that I might have to have more extensive work done on some molars and he will be able to correct the issues with a much less invasive process.

Sarah E. from Carlsbad, CA (Source: Yelp)


Very friendly easy-going staff and great dentist. I have been going here for almost 4 years, and greatly appreciate the ease of their new location at the Forum shops. I also especially appreciate the up to date appt reminders and texts so you know when you’re overdue for check-ups !! Cleanings are thorough and as pleasant as they could be which makes it easier to be a good patient.

Dr. Neff was great, able to get my son in for an emergency appointment when our regular Dentists office was closed for the day. He even personally phoned the next day to check in on him! We will most likely be changing dentists to this office! Thank you to Dr. Neff and his staff, you have a beautiful and amazing office!

Veronica S. from San Marcos, CA (Source: Yelp)


Dr. Neff is an excellent dentist. He takes the time to explain the plan of care.  He has excellent bedside manners and is extremely attentive to his patient’s needs. He puts my anxiety at ease and always makes my visit a pleasant one.  The staff, along with Dr. Neff are professional, friendly and they know what they are doing.  The office staff always follows up with me prior to my appointment and Dr. Neff takes the time to follow up with me after a visit to make sure that I am not experiencing issues with the procedure.  That’s what I call SERVICE!  The office is beautiful and clean, not to mention the technology they use is top notch. Thank you Dr. Neff! I’ve always had a positive experience and look forward to many more.  You make having to go to the dentist a piece of cake (sugar-free of course)!

It’s definitely a pleasant atmosphere. Everyone is so kind and professional. Dr Neff is a great dentist and always follows up with a call. Thank you

Tiffany A. from Perris, CA (Source: Yelp)


Los Coches dentistry is a beautiful office at a great location. The staff is wonderful & friendly. I had my teeth cleaned a week ago from the hygienist & had a great experience, she was very thorough & felt she was very knowledgeable. My teeth felt nice & clean after. Would recommend !

Friendly staff, easy to get appointments, takes UFCW dental insurance and Dr. Neff is great! He explains everything and sets your mind at ease. I’ve been to some dentist that should have been plumbers! Dr. Neff is gentle and concerned throughout your visit!

If most people are like me they dread having to find a new dentist but boy did I get lucky with Dr Neff. He was recommended to me by a friend who had the same dental insurance and I was impressed from day one! First everyone on his staff was friendly and I want to give a special shout out to Gilda who on several occasions was able to get me in for an emergency visit. Second Dr Neff has a friendly demeanor and took his time to throughly review my dental history and recommendations with me. On 2 teeth when others had given no recommendations he didn’t and made several that can potentially extend the life of these 2 teeth! In addition Dr Neff personally called to follow up on more than one occasion after I saw 2 other specialists regarding an issue I was experiencing and that also impressed. He seems to have a busy practice yet not too busy to care about his patients. In todays word, THAT really impresses me. Thank You Dr Neff and staff.

Amazing office, clean, kind, courteous, Dr Neff is so helpful and sweet. He did such a through dental examination and was even there for part of the cleaning. Great place.

Andrea M. from Carlsbad, CA (Source: Yelp)


I have been a patient with Dr. Neff for a few years now and I can highly recommend his practice. They are always professional, kind, friendly and very considerate of how the patient is doing during procedures. They do not push products or procedures that don’t always seem necessary and take the time to explain what they are doing. Offices are clean, bright and modern.

Mehdi S. from Carlsbad, CA (Source: Yelp)


My wife and I have been seeing Dr. William Neff for all our dental work since 2008. We are extremely satisfied with him as he is a highly experienced dentist. He is very professional as he pays attention to the details of his work. He also has a team dental hygienists and administrative staff who are truly professional. We recommend him highly to those who are looking for a great dentist. Mehdi and Nahid Sarram

Dr Neff and team are the best I’ve encountered. To wit, Dr. Neff was able to immediately tell me suspected cause of painful tongue issue. This was after two ENT Drs couldn’t diagnose. After I went back to ENT follwoing Dr. Neff 6 month visit ENT confirmed it was indeed what Dr. Neff suspected. Dr. Neff is the most mindful dentist I’ve been to in 45 years across San Diego county, Chicago, and Seattle. His positive attitutde, dental expertise, professionalism, and all that he does is a credit to his craft. Most recently I went in for cleaning with braces for first time. The hygenist was brilliant and fixed a problem with a wire sticking out. Her cleaning is always thorough and she has great insights. Many who have cleaned my teeth in the past leave a lot ot be desired. At Dr. Neff’s my cleanings have always been spot on.

Nichole C. from Oceanside, CA (Source: Yelp)


Dr. Neff is outstanding. I took my mother here based on the previous reviews and I was very glad that I did. My mother is here visiting from out of town and she got a severe tooth ache and was debating on whether on not to go. My mother has been afraid of the dentist and has had some pretty bad previous experiences. I explained all this to Dr. Neff and he was extremely kind, patient and understanding of her fears. He explained to her what needed to be done in a highly professional manner and even showed videos!!! I appreciated how he did not treat her like a child or talk down to her because her teeth were not picture perfect. She had multiple appointments and he even called her at home to check on her and reminded her of her up coming appointments. I am so grateful to have found someone so nice and caring as Dr. Neff. I’m just upset that they aren’t apart of the BCBS PPO. I hope they join soon! Overall GREAT place GREAT staff GREAT Dr.!

Gilda and her team do an amazing job. I am in and out quickly and every visit goes smoothly. Dr. Neff is the man you want for your dentist. Switch now and you will wonder why you took so long to upgrade.

Jessica Filpi (Source: Yelp)


Los Coches Dentistry is awesome! The staff is friendly and personable, the office is beautiful, and Dr. Neff (I haven’t met Dr. Mudgett but I’m sure he’s great too!) is very professional, friendly, and gentle. The office and equipment are state of the art. Best dentist I have been to.

Rosanna B. from Carlsbad, CA (Source: Yelp)


We have been going to Dr. Neff for more than a decade and have always been pleased with the results.  Besides being a great dentist, he is a sincere and honest human being.  He really makes you feel as comfortable as possible during the visit.  I would recommend him to anyone for sure!

Remarkable care from a remarkable team – thank you. Was on vacation and needed a crown replaced. They worked me in that day and provided great care and a superb outcome. The Doctor and his staff are friendly, engaging, and offer their time generously to allow you to feel comfortable and informed.

Paulette Rosarie Khoury (Source: Google)


Dr. Neff is great! Very meticulous and professional. Always makes sure I’m comfortable, asks a lot of questions and goes above and beyond. His office is nice and his team are delighful and friendly. Highly recommend.

Tanya A. from San Marcos, CA (Source: Yelp)


Dr. Neff has been my dentist for the past several years and I couldn’t be happier. We all know dentist appointments can come with anxiety and are not favorite thing to do. Dr. Neff and his team always make me feel welcomed and I receive great service. Every appointment has been fast and efficient… It’s a breath of fresh air to have a dentist that respects my time. I enjoy there are still dentists around that care about the integrity of your teeth and not try to recommend unnecessary procedures just to fatten their pockets. I love that they put there patients health first so if there is a procedure that may not be covered by your insurance, Dr. Neff offers discounts to fit your budget. If you are looking for a new dentist who is sharp, efficient and affordable make sure you go see Dr. Neff at Los Coches Dentistry… you will not be disappointed.
