I started seeing Dr. Shackelton one year ago and she has helped me tremendously in addressing several health challenges. She truly cares about her patients and takes time to thoroughly answer all of my questions. All of the front office staff, nurses and NREMTs are warm and welcoming as well. I am very grateful for the care I have received at Holistica!

I cannot recommend Jessica Muniz at Holistica Integrative Medicine highly enough. I am a 42 year old woman who has an extensive life-long history of numerous mysterious health issues. I have been in the care of many Internists, Gynecologists, Specialty Gynecologists, Gastroenterologists, Rheumatologists, Allergists, Orthopedists, and the list goes on. Over the years, I have collected an impressive array of diagnoses--each of which associated with a different organ or body system, and each managed by a different medical specialty. There has never been effective communication between docs and a real cross-disciplinary examination of what the hell is going on in my body or why all of these issues are plaguing me. I initially sought help at Holistica with the same mindset I've always had--symptom management or elimination symptoms being the goal. Over the months as Jessica and I have worked together, I have gotten more than that--I have gained an understanding of some whole-body issues that likely explain many of my seemingly "unrelated issues" in my various bodily systems. Together, Jessica and I are chipping away at longstanding infections and other issues that have been foundational to perpetuating my constellation of symptoms. I am very interested in health and medicine and have done a lot of my own learning (ie Googled a lot). As we all know, this is highly irritating and triggering to most medical professionals. I find that when I bring up theories and ideas to most doctors, I get summarily dismissed. It makes me lose confidence in them--if they don't have curiosity to entertain new ideas and think outside of the box, they are not the practitioner for me (because their standard answers have never come close to solving my issues). Jessica is incredibly respectful of my questions and ideas, and collaborative in all ways. I find her depth and breadth of knowledge to be far superior to actual MDs I've seen, and when she doesn't know something, her reflexive response is to reach out to someone who knows more and learn. If you have medical issues that are mysterious to other providers, please give Jessica a try. You will not regret it!

Jessica and her team are stellar and persistent. I have a health issue they were not familiar with but worked to find research and connected with other doctors to help with my silicone detox. it has been a long journey but they have been right alongside me with empathy and excellent care. I highly recommend Jessica and her team.

Mary Shackelton and the Holistica Team have been an integral part of health and healing for me and my family for many years. The level of care and understanding is very supportive emotionally, mentally and physically. Mary creates a space that is open to asking questions which aides in understanding for everyone. Grateful for Holistica!

Dr. Shackelton is equal parts genius and heart and I am so grateful to her and Holistica. Diagnoses (especially those that are really difficult to identify), comprehensive medical treatment, support, and steps toward perfect health are all covered on *new levels* at this clinic. Wonderful in-clinic pharmacy, too. Highly recommend!

Dr. Shackelton and the entire team at Holistica has been fantastic to work with. Dr. Shackelton is very thorough and does an excellent job listening to concerns brought forward as well as offer insights on how different conditions can be related. The entire team has been very responsive, always responding quickly to my messages and have been willing to go to extra mile to make sure I'm comfortable with my course of treatment.

I chose to work with Dr. Mary because of her knowledge of Lyme Disease and approach of treating the whole human. My previous doctor's visits had been short and less than helpful... none had even tested for or mentioned the possibility Lyme and its co-infections. My first visit with Dr. Mary was almost 2 hours long. She looked me in the eyes, asked questions about my mental, physical, emotional health and listened. I have never felt so cared for by a medical professional. She's an incredible problem solver and looks at all aspects of my health, not just zeroing in on symptoms. I also felt like I was apart of the process because she explained things so well and I had choices in treatments. I am on a journey of healing from Lyme and its co-infections and learning so much more about how to live a healthy and happy lifestyle. I feel so lucky to have Dr. Mary in my corner.

Dr. Shackleton was by far the best doctor I’ve had in years. She actually sat down and LISTENED to everything that was going on in my body (which I’ve had multiple doctors and none ever did this). I left the same day with a prescription and in days my body felt the best it’s ever have. I’m 24 and haven’t felt normal since middle school so this was quite the experience for me. I gave up in doctors, but she definitely put the faith back in me. I finally have my life back now, thank you!
