Nurse, 6 Kids & Craved That Silhouette - Houston, TX

Loved him! Awesome guy, great bedside manner. I have recommended him to lots of friends. Go see him!

5 out of 5 stars Liposuction Revision


He was so nice!! He will do what you want but also lets you know what he recommends. He makes sure your comfortable. This is my 2nd round a lipo and he corrected what I didn't like for the dr I went to two years ago. I can't wait to get my thighs done!!!

Snatched Wishes (Doun•siz Houston)

I went to my consultation today. I'm hoping since there was no change in my body when I did SmartLipo, that this is a good doctor to change my mind. He was very friendly and informative about the areas he would work on. He is doing my upper and lower abdomen, flanks, and bra strap. I have a surgery date Feb 22nd for a BBL with Dr Sergio Alvarez. I see a lot of people doing round 2's. So I'm...

5 out of 5 stars Power-Assisted Liposuction (PAL)

Dr. Hennessy is a game changer!!!

First off, let me say that Dr. Hennessy is kind patient, and above all knowledgeable. I had a slew of questions during my free, yes I said FREE, consultation. And he answered every single one. I was told my a few other doctors that I would have to have a tummy tuck if I ever wanted to utilize surgery to achieve a flat stomach, due to my skin being a bit lax. Dr. Hennessy let me know that I...

5 out of 5 stars Liposuction

35 Yo,with 3 Kids Mommy - Houston, TX

I love my new body after my surgery. /liposuction to upper lower abdomen and flank/ Dr.Hennessy is hands down best surgeon in Houston. He does a great job and so honest. I am very pleased my results. Dr.Hennessy and all of his office staff are super kind and caring. You will regret going to anyone else. I highly recommend him.

5 out of 5 stars Liposuction

I had an amazing experience

Dr.Hennessy performed lipo on my abdomen and love handles. He was assisted by a very compassionate nurse, Tuya who held my hand when I needed it! I watched a movie during my lipo and I felt at ease throughout the procedure. I will continue to recommend Dr.Hennessy to all of my friends.

5 out of 5 stars Tumescent Liposuction

Tumescent Lipo Upper/Lower Abs and Flanks - San Antonio, TX

Caring and compassionate. Takes time to listen. Knows what he is doing.

28 Years Old, No Kids, Very Active. Lower, Upper, Flanks. San Antonio, TX

Im 28 years old, very active but could never achieve a flat stomach that ive dreamed for. Ive been on the fence about lip for awhile now. I probably have read every review out there and all the reviews vary. So either this was going to be the best money Ive ever spent or the worst. I'm almost afraid that since i have big hips that my shape would turn out weird. So i decided finally to take the...
