Services
Breast Augmentation
Breast augmentation enhances breast size and shape using implants or fat transfer. Ideal for patients seeking improved proportions or post-mastectomy reconstruction. Our board-certified surgeons prioritize natural results and patient safety.
Liposuction
Liposuction removes stubborn fat deposits to sculpt the body. Suitable for areas like the abdomen, thighs, and arms. We use advanced techniques to ensure smooth, lasting results with minimal downtime.
Facelift
Facelift surgery reduces visible aging signs by tightening skin and underlying tissues. Targeting the face and neck, this procedure restores a youthful contour for a refreshed appearance.
Botox Treatments
Botox injections temporarily smooth wrinkles and prevent new ones from forming. A quick, non-invasive option for achieving a smoother, more youthful complexion with no recovery time.
Tummy Tuck
Tummy tuck surgery flattens the abdomen by removing excess skin and fat while tightening muscles. Ideal for post-pregnancy recovery or post-weight-loss contouring with long-lasting results.

Bestttt experience of my life! Best doctor I could have found! Dr.D helped every step of the way! He was soooo professional, welcoming and I always felt more than comfortable in his office! His staff was so accommodating and all my questions got answered immediatley! I had a great referral and I am so glad I found the doctor for me b/c I didn't really know what I wanted and he helped me figure it out and in the end I am SO grateful for his expertise in this field! I wouldn't recommend any other doctor!!! Started out as a 32 A, small B and now I am a 32D and I LOVE it!!! Recovery has been smooth

I sincerely recommend going somewhere else in the island or waiting to be on mainland. He completed a breast reduction for me and like other review stated, I too waited a long time before submitting this. My breast, scars and areolas are different sizes, big, huge difference in size. Been to a few consultations now on mainland and they all agree it was a procedure done terribly, yet the whole time they made me feel like I was paranoid and things would heal evenly.

I would definitely recommend Dr Dieffenbach because him and his staff are amazing. Very affordable and convenient since I live in Ewa Beach. I did breast enhancements and my results came out amazing to where you can’t tell I got it done.

In 2001, I received breast augmentation from Dr. Dieffenbach. 2 children later, they look just as natural as when I first had them done if not better. Great experience and very natural results.

It been a few months since my surgery and not only am I happy with my results, but my medical condition has improved as well and I'm back to doing all my outdoor activities. Dr. Dieffenbach did a great job, and his staff is super cool too.
Update: it's been a year or so since my surgery. And I was able to successfully lactate for my new born post partum.
