I had one kid go to a highly rated local orthodontic practice. It was a braces “factory” with minimal doctor time and not at all what my second kid needed.  Since we came in with a more complex case, the difference was immediate. Dr Gum has always taken the time to discuss options and been very good talking with my kid.  I noticed quickly all the little extras she provided vs the other office.  When it became time for kid number 3, of course we are going with Dr Gum.  Her office is the one I recommend to friends.

Great orthodontist, amazing staff. Very accommodating. My daughter completed her treatment a couple of years ago and her teeth are beautiful. Now my son is going there.  Yes the office is small but I like it like that. They are pretty good with time management and we never have to wait long.  I do have to say again that everyone is so friendly and nice. We love going to Dr. Gum!

I took my child here to be checked out for braces, and I loved that the doctor did a quick estimate and told us there’s no hurry. She told us he can easily wait an year. In this day and age, where everyone’s out to make a quick buck, that was almost shocking. After having visited a few dentists already, her price was also the best. She may not have a very fancy office but her bedside manner and honesty has won us over already. We are definitely returning next year 🙂

I absolutely love Dr. Gum and her staff! I went to her father as a child for my first phase of braces, so when it came time for phase 2 (as an adult) she was my go to orthodontist. Dr. Gum is incredibly knowledgeable and makes you feel completely comfortable with the entire process, she also does an excellent job of explaining the braces process to you. I highly recommend Dr. Gum to anyone who is looking for an orthodontist! She will also be my children’s orthodontist, I wouldn’t trust anyone else with their teeth! 🙂

I can’t say enough good stuff about Dr Nancy and her fabulous team! They are all so welcoming and positive! I always feel like an old friend when I walk in there! Dr Nancy has been so patient with me; so thorough about explaining Invisalign and what I should expect as I wear them! I am thrilled that my own Dentist, Dr Rickey Fong recommended her for Invisalign!

I have been taking my children to Dr. Gum for the past 21 years (and still am).  My son was 6 when we first went for a front tooth that grew in complete sideways – after she took care of that, he went through braces and maintenance – somewhere in his maintenance stage I took my daughter in for braces who is also now in maintenance.  My youngest started seeing Dr. Gum for an under-bite issue (which was quite an under-bite) when she was four.  Dr. Gum worked with her through her growing phases and you cannot tell today that this was ever an issue – almost 8 years later, my daughter is now in braces.  We moved to Fremont from Campbell 15 years ago, and I have not changed orthodontists because I trust Dr. Gum like no other.  Her staff is friendly and personable.  I would recommend her to anyone.

This is hands down the best orthodontist office around. We checked out a few other orthodontists before deciding to go with Dr. Gum. Some of the other orthodontists may have fancier offices, but there was something about this office that we liked. It could be the calm, casual atmosphere. We appreciate Dr. Gums professionalism and she is also very friendly. Her staff is wonderful too, we especially like Caroline. I wouldnt trust anyone else with my sons smile- which by the way, looks amazing now! Thank you Dr. Gum!!

Dr. Gum has been the orthodontist for my daughters and I cannot say enough good things about her and her staff. First and foremost, I believe that she is very measured about deciding whether or not your child actually needs braces. I have a friend whose child was evaluated by another orthodontist for a very pricy regimen beginning at age 8 that would take many years to complete, and after they saw Dr. Gum, she told them that the child would only need the braces for cosmetic reasons, no jaw malocclusion was there, and it would take approx one year, “but not yet.” She did a free exam of one of my children when my daughter was being seen and concluded he would not need braces. We were already in for 2 kids, she could have easily told us he needed braces too and we would have never known. She has always been caring and attentive to my children. Also, she has a wonderful staff, from Caroline at the desk who is always patient with scheduling appts around school, to all of her assistants who are fabulous with kids. You cannot go wrong being treated by the people in this fine office.

I have two children being treated by Dr Gum. I appreciate that she throughly explains her treatment plans and options. She will take the time with the parents and children to ensure everyone understands the treatment she proposes. She is also is a highly skilled practitioner who is passionate about the care and experience people have with her practice. Her staff is clearly happy to be there and they welcome patients with genuine smiles. I would highly recommend Dr Gum!

I have seen a lot of dentists and orthodontists, jsut cause I wanted like, 2nd and third opinions on what I should do about my teeth situation, and Dr. Ferguson referred m to Dr. Gum. Dr. Gum’s office only has 3 chairs, but it made me feel casual and calm. She was very nice and very professional and answered all of my questions. I really like Dr. Gum and she will be the one who will be putting braces on my teeth.

When we came to Dr Gum, both me and my son were apprehensive. He had been a thumb sucker since infancy and was still struggling to stop. Dr Gum was amazing. She did not shame him in the least bit, unlike the two other orthodontist who likely did so unknowingly. She helped him identify what his triggers were and then how to break the habit. We had 2-3 follow up appointments on this issue before actually starting treatment. I will never forget and always appreciate her kindness and most important…her competence as an orthodontist. Also, noteworthy, her staff members are just as stellar as she is! I feel like we hit a home run finding this office. Highly recommend!

When I have a great experience, I am compelled to share!  The “teen braces” experience can be daunting for both the child and parent and after near completion of treatment of my two teens, I am relived and happy to share that our experience was a great one from both perspectives.  Both of my kids have raved about how Dr. Gum and her staff were caring, open and friendly!   From the parent’s perspective, every step was clearly planned and executed.  Dr. Gum was great at holding the kids accountable for keeping up their end of treatment which was so refreshing.  The kids and I are grateful for the great new smiles and the smooth and caring process to get there!  Thank you to Dr. Gum and your entire staff!!

Dr Gum has been amazing with my son from start to finish! She and her staff were always very welcoming and easy to schedule with around school commitments. My son understood what he needed to do to get his braces off on time and it was explained to him as his responsibility, not up to his mom to nag him about wearing his neck gear, etc. I used a different orthodontist for my older sons which really turned into an ordeal between scheduling around high school commitments and long delays in treatment. I only wish I had found Dr Gum sooner!

My rating for Dr. Gum may be relatively premature, since I haven’t actually received treatment from her yet. My first impression of Dr. Gum, however, was very positive, and I will be seeing her for treatment in the future. Dr. Gum is very friendly and professional. I brought in information from my old orthodontist, and she took some time to look over the pictures. She asked that I hold off on telling her his opinion though, until she had a chance to look for herself and form her own opinion. She was very understanding of all my concerns and honestly told me the extent of the treatment I need, as well as that she could not guarantee the treatment would be permanent. She provided me with all the information I needed and told me to think about it and let her know what i wanted to do I think this shows great professionalism and care. She didn’t push for treatment to get my money. She also sounded very thorough and careful- moreso than my previous orthodontist, and I feel much more comfortable pursuing treatment here even though it will be more expensive (would have gotten a second-treatment discount of $2000 from my other orthodontist).

I was originally going to go to another orthodontist in Saratoga to fix my younger daughters teeth. We did the x-rays, molds, consultation, etc. My older daughter wanted me to take her to see Dr. Gum because she went to school with her daughter. At that first appt with my older daughter, I was very impressed with Dr. Gum. She is very calm, professional and answered any question I had. After thinking about it, I decided both of my girls should see Dr. Gum. Dr Gum’s office is small (I believe she only has 3 chairs) and it’s not super fancy. However, that is exactly what I liked. I felt so comfortable there. The other orthodontist had marble floors, a latte maker, etc. While those are all nice, I also don’t really care to pay so much more ($1k for phase one, $2k-$3k for phase two) just so I can have coffee while I wait. So far, I am very pleased with making the change even though I have to get the records transferred, etc. If you are looking around for an orthodontist, be sure to get at least 3 opinions, and include Dr. Gum as one of those.
