Maria Kamvouris is by far the best person I've ever had to deal with at the Cleveland Clinic! She makes me feel like she genuinely cares about my health and well being. She always takes her time in explaining everything and she never takes any shortcuts. I've been dealing with the Cleveland Clinic since March of 2018 and I've had only "good" experiences with everyone who has helped me with my issues but, Maria takes it to another level to be completely honest. After meeting with her and I leave I never feel as if I have anything else I need to know because she always explains everything to the point of me having 100% of the information I need. I cannot say it enough, Maria is the exact reason why I know I made the right choice by going to the Cleveland Clinic every time! Hopefully she stays in her position for the foreseeable future because I couldn't fathom having to deal with anyone else. When it comes to healthcare she is the epitome of doing things "the right way"! In my humble opinion, she deserves a huge raise just because of how easy she has made it for me the past year since I've been dealing with her!! Normally I cannot stand going to a hospital and/or a doctors office but when I know I have to meet with her I don't worry about it at all because, like I said before, she makes me feel like a real person and that she only cares about me feeling the best that I possibly can! I cannot say it enough, Maria has helped me more than I can ever put into words to make me healthy and feeling better about any health issues I have. Please, don't let Maria go anywhere, haha!! Obviously with someone as good as her, she won't be there forever but she has helped me in the most astounding way and in ways I never thought a medical professional ever could considering my health issues. It's so darn easy to deal with my health issues when the Cleveland Clinic has employees like her! I've told my family and friends about how good she is and I think that alone may sway them to more than likely consider the Cleveland Clinic for any health related issues. This is long and drawn out but I cannot help it because this wonderful lady has helped me so much and made it much much easier to face and fix my health issues! Keep up the good work because The CC is obviously hiring the right people!!
