5 out of 5 stars Laser Liposuction

Lips to Upper and Lower Abdomen,flanks, Inner and Outer Thighs, Chin and a Silicone Breast Enlargement - Aiea, HI

Dr Dieffenbach and his assistant Jenn are wonderful people they make you feel comfortable from the first phone call and office visit. Honestly I had 3 consultations set up with different drs but from the get go I told my husband that I think dr Dieffenbach would be the dr I choose cuz I jus had a good feeling about him but we would see after the consult. After my consult with him I canceled my other appointments. Dr D is in my opinion, a quiet guy. He and Jenn give you all the info you need and answer all and any questions you may have. They do not make you feel like you are just a payment in their pocket. They make you feel welcome and apart of their family. I had literally a list of questions when I went for my appt and I was apologizing for so many and dr D would reassure me that there is never a dumb question or to many questions and that he wanted me to feel comfortable with my decision and to be well informed. Not one time in any of my visits, phone calls or emails did I feel unimportant or like I was being rushed. I felt truely cared for and reassured. Another thing I appreciated about dr D was that he never tried to push anything else on me or suggest I get more surgery areas. He even mentioned that I could go saline to save money. He truely cares about his patients and listens thoroughly to our wants and desired outcomes. He will not sugar coat stuff to make you think it will be a walk in the park. He will tell you his opinion but still give you the final say as long as it won't be harmful to you. Even during the awkward part of getting nude in front of him when you discuss your desires and the outcome you wish for was not bad and Jenn is in there as well. From beginning to end it was a GREAT experience and I seriously, HIGHLY RECOMMEND Dr Dieffenbach and staff. He will keep your health and desires a priority. Very friendly staff. I can't say enough good things about my experience with them. If you are considering any type of service they provide I hope you will go for a consult with them.

26 Years Old, 1 Child, Was Always Unsatisfied with my Breast - Aiea, HI

Dr. D is absolutely the best. Of course I had so many doubts and questions not about him doing the surgery but me not knowing what to expect. He answered every question and doubt I had and really gave me a reassurance that everything would turn out perfect. Leaving everything (all my worries) in his hands was definitely worth it! He is absolutely one doctor who actually takes you into consideration and makes you feel special and not like you're on of many women doing the same old procedure. I would definitely recommend Dr. D to all my friends and family knowing that he can give them the best care as he did for me!

5 out of 5 stars Mini Tummy Tuck

Dr. D Mini Tummy Tuck - Oahu Island, HI

I can't say enough about Dr. Dieffenbach! The experience was so much better than I imagined it to be. I was completely at ease and the procedure and recovery discomfort was minor. I was referred by one of my employees who also had a fantastic experience and is extremely happy with the outcome of her breast implants. If you are considering a procedure I highly recommend going in for a consultation! There is no pressure to do anything more than you want to and the different options made it easy for me to decide what was right for me. Mahalo Dr. Dieffenbach!!

Breast Augmentation and Lipo - Aiea, HI

Dr. D and Jenn were both so kind and friendly. I was nervous to go in there and bare all my flaws to someone I do not know. From the first phone call Jenn has been so sweet and patient, she answered all my questions (phone, emails and in person) without making me feel like I was being a pest. I went in and filled out paperwork then watched videos in a private room. After videos were done I went to another private room and felt implants with my hubby while we waited for DrD. Dr. D was so gentle and kind, my husband even liked him. I didn't feel so bad baring it all in front of him as he was easy to talk to while he showed me things and made suggestions. He gave me options and never forced his opinions/ideas on me, only made suggestions. I felt a little weird cuz I did so much research and ended up bringing a big list of questions I had for him. Not once did he seem bothered and he even said many times "that's a great question". So far everything has been good. I would recommend Dr. Dieffenbach and staff.

50 Years Old, 2 Kids. Honolulu, HI

I loved my experience with Dr.Dieffenbach and his team. They are very well informed and welcoming. He answers all your questions even though he is the expert. I basically asked him "what do you think" and he would reply with his personal opinion but always kept my concern in mind. His two assistants made my experience comfortable and pleasant.

5 out of 5 stars Eyelid Surgery

67 Year Old Active Grandma Ready for a Remake. Aiea, HI

I recently had surgery done on my droopy eyelids and very bad puffiness under my eyes by Dr. D. Dr. D. did an awesome job. He walked me through this whole procedure from consultation to results. He is very trustworthy and takes so much consideration in his patients. Surgery was painless and healing was very comfortable. Thank you Dr. D. for making me feel so confident with myself again. Results were AWESOME. Staff were so helpful and wonderful; second to none.

5 out of 5 stars Breast Implants

breast augmentation - Aiea, HI

From my initial consultation to my 6 week post op visit dr. D and nurse jen were amazing! As many mothers do, I put the needs of my children and family first and waited until I turned "50" to begin my search for the "Just right" dr. To finally be facing this decision I knew everything had to be just right. From the first visit I felt very much at ease and was very confident in making my decision to go with dr. D and his team. He was extremely helpful in guiding me through the process and assisting me with all of my questions and concerns. At no time did I feel rushed or pressured to make any immediate decisions. With the knowledge and experience dr.D shared with me, I was able to make a decision that has made me feel confident and happy beyond my expectations.

46 Yr Old, Mother of Two, 475 Cc Silicone Under the Muscle

Dr. D really took his time explaining my options and what I should expect with the breast augmentation. He answered all my questions and was attentive to my concerns. I am athletic and a mom so I wanted to go as big as possible without looking ridiculous or interfering with my workouts! I absolutley love, love, love the results!

5 out of 5 stars Mommy Makeover

Dr D's Mommy Makeover Gave Me my Life Back - Aiea, HI

Dr D an Jenn both spent a lot of time answering all my 'stupid' questions before and after my surgery. They made me feel like family.

5 out of 5 stars Breast Augmentation

Satisfied Patient - Ewa Beach, HI

Dr D and his staff were so professional and treated me with respect, from day one. Dr D and his office staff made sure that I understood each and every step of the process. I had a pleasant experience with each appointment leading up to the procedure and continue to with my annual checkups. My choosing Dr D was from a colleague's referral and I am happy with the outcome.
