I hate going to the dentist. Dr. Cassidy was very understanding and caring, his staff was wonderful. Katherine did my fillings as well as distracted me enough that I forgot I was in the dental chair! I’m so grateful I found such a wonderful office. Thank you all for the professionalism and Katherine, thank you for the compassion!!!

My experience with Dr. Cassidy and his staff over the last few decades have been effortless! Appointments are easy to make and the staff is very helpful. The EF, Kat, has made coming to the dentist a very enjoyable experience! And the views aren’t bad either. I highly recommend Dr Cassidy and his helpful and knowledgeable staff for yourself and your family.

Best dentist I have been to hands down. I've been going to Dr Cassidy for over a decade and recommend everyone to him. The entire office makes you feel welcomed and they are very caring. Dr Cassidy is very gentle and makes you feel calm during difficult procedures.
Other dentists previously had pushed for procedures that I didn't think I really needed and I wanted to get a second opinion. Dr Cassidy saved my teeth from major work that was unwarranted or needed and would have just been for profit. Dr. Cassidy is truly a gentleman and cares about you and is not out for profit.
Also I have to mention

Dental hygienist attempted to talk to me entire time(pet peeve of mine when people have there hands in your mouth) and was also very condescending to me on me not coming in more frequently. Was also trying to sell me on other services that were not requested. Overall not a pleasant experience.

So I hate to do this to any business but I need to not be silent. Check your bill!! My husband and I moved to Tahoe and both started going to this dental office. For almost two years. And although the cleanings were excellent, the billing was always inaccurate and misleading. We absolutely were taken for a ride and over charged by the friendly woman at the front desk. After multiple services and multiple mis-charges, we began to push back with questions. Our concerns were brushed under carpet and given the run around by the friendly front desk woman. Finally we had to insist on cost breakdowns

I have been spending several days in South Lake and broke a tooth, not returning home for several more days, I found this dentist and called them on. Friday at 8:30 AM. They took my info and said they could fit me in at 1:45 pm. Check in was easy, especially in this Covid world, everyone was friendly and helpful and they examined me and determined they may be able to do a repair if I was willing to wait 30 minutes or so. No problem, they got me in and several of the staff worked on my damaged tooth. I left at 3:45 PM! Professional, courteous, painless...I am grateful to these folks for resolving

I have to have my teeth cleaned every 3 months, and there is no better hygienist for my needs than Rhonda.
She is gentle(very important), informative and genuinely concerned for her patients.

I highly recommend this Dentist office.
I had a crown come off from work done while back at different dentist.
Katherine booked me to come in within a day.
Roberta replaced my crown and provided very professional service.

My experience was smooth and unstressful!

My husband and I recently moved into the area and chose Dr. Cassidy and his amazing team just based on his website. Are we ever glad we chose this office. They are friendly, professional, knowledgeable, but also very light and fun. We have been there twice now and never have waited more than a few minutes to be seen. We do not like to have too many x-rays taken and this rice works with us on our decision. In addition, I am very affected by novacaine and upon hearing this Dr. Cassidy thanked me for telling him and found another way to numb my mouth which worked amazingly well and I felt no pain

Ronda and Roberta are the best! They get a 10 from me!!! I came in without an appointment, and I am not a patient. It was Friday at 4:00, so most offices are probably not happy that somebody just walks in for help. I was in pretty bad shape, and they both made me feel so welcomed. They have the Tahoe spirit. I had a very sore infected tooth inside my crown that needed antibiotics immediately. They took an Xray, and offered to email the images to my Endodontist in the Bay Area. Dr. Cassidy had them prescribe me a heavy dose of Amoxicillin and off I went. When I asked how much, they said

I used to get so nervous going to the dentist until I started going to Dr. Cassidy. Everyone in the office is just truly amazing and welcoming! You truly feel so calm once you get into the dentist chair and the staff is so friendly. If you are looking for an outstanding dentist in Tahoe this is 100% the place to come!

I am new to South Lake Tahoe and needed to find a new dentist. I was very pleased with Dr. Cassidy and the office assistants. They spent a lot of time with me explaining everything and their office is in a beautiful location with a great view of the marina. I would highly recommend coming here if you need a dentist.

I may be a little biased because I work here however due to that fact I can review Dr Kevin Cassidy as a wonderful, professional & knowledgeable dentist who does care greatly for his patients. I know so because I work by his dude all day. I am his Registered Dental Assistant and I highly recommend anyone considering dental work to make an appointment by calling and talking to Roberta or Rosie both are wonderful front office staff extremely knowledgeable in their field. We all care greatly about our patients and continue to improve our skills. I have just moved to Gardnerville Nevada down the

Have been going to Dr Cassidy for as long as I can remember (20+ years), everything is great except DO NOT go there for Invisalign. I didn't know in the beginning but there is a tier offering called Unlimited - which means you're able to continue until you're satisfied. Had I known I was paying for this I probably wouldn't have paid extra, but after a complicated procedure that took more than a few years, I was glad I had it. I thought I was almost done with one slight correction left when I was told that my treatment had expired. I now have buttons left on my teeth and rude

Dentist is unheard of and a lovely office staff. I had a chipped front tooth and I went through several dentists, over and over and over, who would fix the chip and it would fall off again every six months, as it's a difficult tooth to fix. Dr. Cassidy worked my tooth, and permanently fixed it, I was very appreciative! I was also helped by Victoria who did great work, smoothing out my front tooth. Thank goodness for Dr. Cassidy, his employees, and office staff.

Dr Cassidy himself is a good dentist. My problem lies with the rest of the staff. I was told that my insurance would cover all of my daughters expenses which by the way were standard procedures nothing more. She's never had anything wrong with her teeth. Two years later I receive a bill for more than $600. They are not willing to work with me whatsoever. The mistake was made by the staff and now I am extremely enraged and would never step foot in this office again. She was only seen by Dr Cassidy once and had a cleaning twice with routine services. Our bill is over $600? Mind blowing!

"They call me yuck mouth, cuz I don't brush!" Ages of neglecting oral hygiene caught up with me but every member of the professional staff here has invested in my well being as much as I've invested in services rendered here! Cavities, chipped teeth, a crown, NO MORE FROWN! "Fix your teeth, change your life!" My experiences here are priceless but I was charged extremely reasonable prices for the tremendous amount of detail work done. I waited awhile to write this but there have been NO complications, everything healed greatly, & I AM super grateful to each thoughtful
