Axillary/bra Roll Lipo
I had a great experience at Downsize Lipo. Dr. Hennessy and Ms. Maureen were extremely kind and accommodating. Throughout the consultation, surgery, and post-op care, they were consistently patient, professional, and communicative. Recovery was easy, and my results are excellent. I would 100% recommend them.

If I Had to Do It Again, I Would.
I have never had cosmetic surgery before in my life. This journey of finding a great team was very nerve-racking. During my consultation meeting, the staff at Dr. Hennessy has was by far beyond the most welcoming and warming individuals that I’ve ever met in this industry. The entire team make sure that they take care of you before a patient as a person. They’re on call 24 seven for whatever you may need. They explain to you thoroughly in detail of what you need what you make

Best Lipo doctor in Houston! Upper & lower back, flanks & axillary
One week out. Lipo on Upper and lower back, flanks, Axillary. Dr Hennessy and staff are wonderful I'm 68 years old and went to 2 different Dr's before choosing Downsize. Dr Hennessy knows how to sculpt your body. I have a one week checkup tomorrow and only concern I still see arm pit fat sticking out. I'm sure Dr. Hennessy will make sure I'm taken care of. I may need small lipo done on the front of my arm pit. I thought that was the Axillary area IDK. I'll keep you posted

I'd pick Lipo over a root canal any day
After hitting a roadblock in three different clinics, I was almost ready to throw in the towel on my Lipo dreams. Then, enter Dr. Hennessy—recommended by a friend of a friend, and boy, am I glad I made that call. Maureen, the office manager, was a rockstar—informative, professional, and as welcoming as a warm hug. Finally meeting Dr. Hennessy was a game-changer. He radiated confidence in the results, and guess what? He nailed it! Shoutout to David, the Surgery Tech, for being

I got the hourglass figure I wanted
I am beyond happy with my liposuction 360 results. I only wish I would have done it sooner. It was such an easy surgery. Not a lot of pain, just a little discomfort. I got the hour class figure I wanted. Dr Hennessy and his team are Great!! They make you feel so comfortable. They really took care of me. It was also affordable right here in the United States. Stop thinking about it. Go to Downsize Lipo Center of Houston today and get SEXY!!!
