Dr. Sebastian,

Everything is going great!!! I am always amazed at how good I feel after these surgeries!!! I contribute that to having a great Oral Surgeon and your assistant. I can’t remember her name, but she is so awesome!!! I have not really had any pain. When I came in this morning, the little problem I had was fixed and I was on my way, still without pain. Thank you so much for your great work and concern!!! I would recommend you to everyone!!!!

Dear Dr. Sebastian,

I almost can't believe I have a full set of teeth again. For over 11 years I have had one issue or another with my jaw. Until I started seeing you a few years back I had constant pain on the left side of my face. I was thrilled after my first visits with you. The absence of pain was an incredible relief, but to have a full set of teeth and no pain is more than I hoped for.

There's been a lot on the news lately regarding Oprah ending her show and so much talk about how she has changed people's lives. It got me thinking about how remarkable you and your staff are and how all of you have changed my life.

I lived with constant pain (literally for years) and constant dread of seeing another oral surgeon or specialist until I met you and Carrie, Becky, Stacy and Lisa. You taking over my care and your team assisting you changed my life from the very first appointment I had with you. I now have no pain, a healed jaw, a full set of teeth, and my smile back because of you and your wonderful staff.

I don't know how to thank all of you. I just hope you know how much I appreciate all you have done for me.

Thank you for doing a great job on my crown lengthening. You are excellent at what you do and very professional. Your staff is to be commended also for their gentle care with patients, relieving them of their concerns and making sure they are comfortable. Your whole team made a stressful and frightening procedure easy. I would gladly recommend your practice to my family and friends or anyone in need of a periodontist.

Thanks for your email, Mark. Yes, all seems to be doing well. Very minimal discomfort. Ibuprofen works well. I've been following instructions.

I really must commend you and your staff for the high degree of patient care, efficiency, attention to detail, friendliness, interest in patient comfort, and congeniality and more. It seems to be reflected throughout your office, both front and back. My overall experience rates an A+. Thanks, again.

Good Evening,

I would just like to say that it has been a pleasure coming to you for dental services. You and your staff are so warm, professional, and caring. You do wonderful work, and I am almost sad that my work is completed (not fond of the dentist, so almost). I shall refer you to anyone who needs this type of dental work completed. I appreciate the post call/emails to check on me, and how your staff go out of their way to accommodate patients and make them comfortable. Thank you for the beautiful flowers and hope everyone had a wonderful New Years!

P.S. My mouth is healing nicely, there are no complications.

Dr. Sebastian,

I have always been a "basket case" going to the dentist, but Five Stars to you and your staff for making my visits painless and reassuring. You actually made me laugh. The work was expertly and professionally done and the results were beautiful. Thank you again.

Dr. Sebastian, it is pleasure to be your patient and to visit your office. I feel lucky to have finally found you.

Dr. Sebastian,

I can’t thank you enough for the work you have done on my teeth and jaw so far. For six years I had daily pain in either my upper right or left jaw, often times both. I saw numerous endodontists, two oral surgeons, had three root canals in one tooth, and sinus surgery all to no avail. I have been pain free since my first procedure with you. I honestly didn't think pain-free was a possibility anymore. I know I have a few more treatments/procedures to go before I have a full set of teeth again but I am so hopeful and happy with the results. I am writing this note to make sure you know how grateful I am. I also want to take a moment to tell you how much I respect and like your entire staff. Not only are they helpful and kind they are over the top knowledgeable. Everyone has gone above and beyond to help me. Carrie has gotten me on the schedule when I thought it would be impossible. Lisa met me at the office so I could pick up paperwork when the office was closed. I've learned more from Becky since I met her than all my other dental related appointments combined and Stacy has a way of putting me at ease (which I guarantee is hard to do).

Dr. Sebastian, it is pleasure to be your patient and to visit your office. I feel lucky to have finally found you.

Dear Dr. Sebastian,

Over the years, I have been blessed with many wonderful healthcare professionals including you and your staff. You have provided me with excellent periodontal care in the past 13+ years and I wanted to let you know how much I appreciate it. You have always given me an honest opinion of my oral health care needs and have done an outstanding job on the surgeries and grafts I needed.

I would recommend you to any of my friends and co-workers in need of periodontal care. Many thanks again to you and your staff for this excellent care.

Dear Dr. Sebastian,

Let me start by saying, I rarely write letters for good services rendered, but I feel your service is exceptional and deserves notice.

Dr. P just completed the crown on the implant procedure you preformed last year. This letter is to thank you for the wonderful work you have provided me over the last 10 years.

I shop for dental care. Your prices are significantly below your competitors. I find it hard to believe the competition could be as competent as you. You are worth my travel from South Hill Puyallup to Federal Way.

I received several implants, and a sinus graft by Dr. Sebastian, necessitated by an accident and some prior extractions. The process was painless, I have had much more discomfort from a filling, and the final results truly exceeded my expectations.

I honestly cannot tell what teeth are implants and what are my original teeth. The appointments were all on time and the entire staff was extremely professional and very pleasant to contact with. I can and do highly recommend Dr. Sebastian and staff for your dental needs, they are great.

~RW
