testimonials

  • Dr Alyssa was a God sent angel! I’ve been to so many doctors and natural healers to try and get to the root of my symptoms but still felt horrible and never got to the root of the issue. Once I met Dr Alyssa, she took the time to answer all my questions and educate me about where things were going wrong. I finally had answers that resonated with me. She was always super patient and kind during our sessions. Fast forward a few months and I feel so much better! My cystic acne is a thing of the passed, I got my period after years of an inconsistent cycle, and I feel good both physically and mentally. I went for my acne but she helped with so much more than that. I went from chronic headaches and discomfort and fatigue to feeling good and energized. I didn’t know it’s possible to feel this good. If you’re struggling, don’t think twice! Dr Alyssa is your answer! Would highly recommend to family and friends.

  • Dr. Alyssa DeSena has already helped me so much in only two visits. She takes the time to listen to what is going on and work with you to figure out where to start. She made me feel heard and I was so grateful to already receive results after just a few tests. Looking forward to continuing with Dr. DeSena and what the future holds.

  • It’s clear that Dr. Alyssa knows her stuff and is actually listening to my concerns. I’ve never had that happen to me before.

  • I always leave healthcare appointments feeling defeated, unheard and sometimes a little crazy. But not with you!! Thank you for helping me navigate these issues and work towards finding the root cause!

  • My visit with Dr. DeSena was amazing! She is super nice and is very caring. She is always looking ahead in terms of what to do next in my treatment, and always recommends the best supplements for my needs. I honestly don't know where I would be without her, health wise because I feel much better now! I cannot wait for the next few months!

  • Dr. Alyssa is so easy to talk with and very down to earth. I felt comfortable speaking with her right away.

  • Dr. Alyssa is so thorough and caring. I feel like she really listens to me and is making very helpful recommendations. I look forward to continuing to work with her.

  • Dr Alyssa is so sweet and thorough! She took the time to get to know me and address all my concerns. She’s really pleasant and easy to talk to. She also made herself available over messaging after visits for any questions that came up. Would definitely recommend!

Wondering what you can do this week for clear skin? Dealing with acne usually comes with some detoxification issues and supporting your liver can help get toxins moving along👉🏻 out of the body so they can stop wreaking havoc on your skin Swipe f
