Working with Dr. Delplanche and the Lake Oswego Orthodontics staff has been a pleasure. Dr. Delplanche took over the practice during my active treatment phase and I was unsure about this; however, I am glad that I remained a patient of the practice and now, that I have a great smile! The doctor and his assistants ensured that my case was progressive to the outcome. Dr. Delplanche is more than fair with billing practices, and the staff is good at accommodating unplanned appointments as needed. Thank you Dr. Vanessa Peterson and Dr. Delplanche for transforming my smile!

Excellence all around - Dr. John Delplanche and his staff could not be kinder or more professional. Marci is especially sweet and easy to talk with. Highly recommend this practice!

Dr. John Delplanche recently took over my care and this practice from Dr. Vanessa Peterson and her husband. I started with her, but my understanding is that she moved out of state on family matters.
I could not be more impressed with how committed Dr. Delplanche and his staff are with getting me the best results despite a prior poor Invisalign treatment from a dentist. This is what Dr. Peterson had started to fix and thankfully Dr. Delplanche will continue.
Lesson learned and shared: an orthodontist, not a dentist, should provide your orthodontist care for best results! There's additional education and training for this specialty dentists don't receive even if Invisalign allows them to take trainings, sometimes as little as over a weekend!
It's not the same high quality care in my experience nor in your best interests any more than those new mail in low cost clear aligner treatment trays competitors offer.
Your bite and your teeth need to last your lifetime. Don't just get your teeth straightened for cosmetics; make sure your bite is also being properly aligned too or you'll be sorry!
Transferring care has been seamless. He's a funny, gentle guy with a serious side, paying attention to detail and even going the extra mile for patients like me. He really takes the time to explain everything in very understandable detail. I've heard he's great with children too! He puts me at ease and I'm an adult, nervous about even going to the dentist!
Dr. Delplanche is also Board Certified just like Dr. Peterson. I highly recommend him!

Everyone was super fun and friendly. I was never left out of the loop and was always told what was being done.

Everyone at the clinic was very kind and professional. Office was clean, ran on-time with quick and thorough appointments. Best ortho experience ever!

We drive across town to your office because we’re so happy with your practice and don’t think we could find any better!

This place is excellent. The service is so friendly and inviting. I recommend them to all my friends!.

Had the best experience with this place! Very friendly and knowledgable staff!

I was very pleased with how welcoming the staff was and how clean and organized everything was. Definitely would recommend to anybody looking to have a relaxing and thorough dentist visit.

I'm absolutely thrilled with my experience at Lake Oswego Orthodontics. Sweet bedside manner, top rated service, all in all a professional but welcoming visit start to finish. Thank you so much for taking such good care of me!

I love to come here, the doctors take extra care to make me feel comfortable. The reception staff is wonderful, especially Joanna. She is such a bright presence in the clinic.

I love the staff, there so personable. They make going to the dentist not bad!

I cannot say enough good things about the staff and service. The floors were so clean even though it was a rainy day! I was very impressed and recommend this place to anyone that needs to get any serious work done to their teeth or mouth!

Oh so pleased!

I loved the location, and the staff were swift and friendly. I highly recommend them. Joanna was very kind and helped me when I arrived.

Had a consultation and everything was amazing. The staff and doctor was friendly and very accommodating.

Very welcoming and communicative about the services and procedures. The staff is very positive and makes sure everyone is smiling.

Dr. Vanessa & Andrew Peterson became the new owners towards the end of my treatment but they were so kind and efficient that I felt like keeping my braces on for longer! Dr. Vanessa Peterson is the sweetest person ever with excellent customer service and truly makes every patient feel cared about no matter how long their treatment has been. If you are looking for a nice orthodontist that also gets the job quickly done, you should most definitely go to Lake Oswego Orthodontics and Periodontics!

Dr. Peterson is amazing at what he does.  He has excellent doctor-patient manners and communicates with me to make sure that I am comfortable.  I wouldn't go anywhere else for my Periodontic needs.

We had the best possible initial consultation with Dr. Vanessa Peterson recently. My daughter is just 7 years old but has a lot of crowding and I was concerned about getting an early start on treatment. Dr. Peterson and her staff made sure my daughter was comfortable from the moment we came into the office- they are so warm and friendly! She examined her, gave me some helpful information about her current situation and possible first steps, and I left feeling confident that we have a plan. I would recommend Dr. Peterson to anyone- it's even worth the drive if you're not in Lake Oswego!

Such a wonderful experience. Relieved my anxiety right away and walked me through everything step by step. I felt very well taken care of. I highly recommend them.
