Dr. Joanna Lee

Just Laughs, Just Smiles, Just Kids!

Dr. Joanna Lee

DMD

Location: Downtown & Mission Hills

Hi, I’m Dr. Joanna Lee. I was born and raised in Castro Valley, California, and have always enjoyed working with children. I’ve had the opportunity to travel abroad to Mexico and Honduras on humanitarian trips, which deepened my passion for service. I completed my undergraduate studies at the University of California San Diego, then earned my dental degree from Roseman University of Health Sciences College of Dental Medicine.

I began my career in private practice in San Jose, where I discovered how fulfilling it is to make a meaningful impact on a child’s overall health by addressing oral health early and helping prevent future dental issues. That experience inspired me to pursue additional training through the NYU Langone Pediatric Dental Residency in Hawai’i, where I served communities across Oahu, Maui, Lanai, and Hawaii Island.

In my free time, I love hiking and am always thinking up new arts and crafts projects. I’m excited to bring my energy and experience to the office and look forward to providing personalized care that meets each child’s unique needs.

Abhishek S.
The staff was caring and excellent. My child felt completely comfortable, and the cleaning was done without a single tear.
Megan M.
We (parents) were expecting a full meltdown during our son’s visit but staff was so friendly and made him feel comfortable that he made it through without one tear. Got a fun dog balloon and all. Great experience!
Nidhi G.
Very cooperative and pleasant for kids. I am usually very critical but would definitely recommend this place for kids
steffie G.
Everyone at this dentistry was so friendly and welcomed us with open arms. The office felt like a daycare and dental clinic all in one. They have screens on the ceiling playing cartoons, so the kids can watch TV and feel comfortable during their visit. Instead of the regular adult sunglasses, they use fun kid-sized ones to block the light.

My child had a wonderful experience! They even made a balloon dog, just like at a party, and gave a toy at the end, along with a toothbrush and toothpaste. This office truly gives you an experience you won’t forget!

The staff works with the kids as if they’ve known them forever. The office is clean, well-sanitized, and the doctors are wonderful. I especially loved my assistant—she was sweet, attentive, and on top of everything. I can’t wait to go back! I only wish they saw adults too, because I would most definitely be a patient myself.
Response from the owner:Thank you for your wonderful review! We're thrilled to hear that your child had such a positive experience with us. Our team is dedicated to creating a fun and welcoming environment for all our young patients. We look forward to seeing you again!

Both my daughters went there and they were amazing. They let both my kids go in at the same time to help me manage them. Then made sure my kids felt comfortable. They also made my kids balloon animals and gave them a free shirt for their first visit!

Wonderful first experience at the dentist for my one year-old. Although he didn’t enjoy it lol The staff was friendly, sweet, and made the experience one I’ll remember.
Response from the owner:Thank you, Dani! We're thrilled to hear about your positive experience with us. Our team is dedicated to making dental visits enjoyable for little ones. We look forward to seeing you both again soon!
Nataliya K.
Very good doctors and assistants.
Only one annoying hiccup.
They charge $5 for credit card payment on any amount. I paid $135 plus $5 for credit card payment.
Even small grocery shops don’t charge if you pay more than $10 with credit card.
I hope someone listens
Response from the owner:Thank you for your kind words, Nataliya. We appreciate your feedback regarding the credit card fee and will take it into consideration. Your satisfaction is important to us, and we value your input.
Nikki L.
Both of my kids have went to different pediatric dentistry and I'm really glad that we've found Just Kids. The staff and dentist there are super nice and the waiting area has a lot of books and arcade machines to play with. There is a big TV on the ceiling so my kids would just look at that and not be bothered by the work performed on them. The staff would also give them a balloon and a coin for toys. Everything was clean and we were in and out within 30 minutes. Easy to make appointments. Highly recommended!
Response from the owner:Thank you for your wonderful review, Nikki! We're thrilled to hear that your kids had a positive experience at Just Kids. Our team is dedicated to creating a fun and comfortable environment for all our young patients.
Rishi S.
I am super pleased with Just Kids and their entire team.
I must say we are very blessed to have such a great Doctor. My two kids just love going there. Dr. Pooja Rattan and her assistant Alisha are just so wonderful to our kids. They always make sure the kids are comfortable before any procedure. Dr. Pooja always assures she preps them before proceeding with the procedure making awareness to the kids as what's to come. This really helps my kids feel at ease. Even during the procedures Dr. Pooja and Alisha are always talking to my kids making sure they aren't in pain. It's very comforting. I'm very happy with their service and level of professionalism.
God bless you all!!!!
Response from the owner:Thank you for your wonderful review! We're thrilled to hear that your kids enjoy their visits and feel comfortable with Dr. Pooja and Alisha. Your satisfaction means a lot to us!
