My family and I have been coming to this Labcorp location for more than six years, and for most of…read morethat time our experiences have been very positive. Unfortunately, my experience with the same front-desk employee on two separate occasions once in December and again today, more than six months apart has been very disappointing. Today, I accompanied my wife for routine lab work. While the front-desk employee was checking us in, I simply asked a polite question to confirm that all five tests ordered by her doctor had been included. The tests had been ordered a couple of months earlier to be completed now, so I wanted to make sure everything was correctly captured. Instead of simply answering the question, his response and demeanor were unnecessarily dismissive and disrespectful. When I asked why he was responding that way to a straightforward question, the interaction escalated. He spoke to me loudly and told me that we were not there for "action and reaction" and accused me of raising my voice, even though I had been speaking normally up to that point. I eventually responded firmly that he also needed to lower his voice and speak courteously. What makes this particularly disappointing is that I had a similar negative interaction with the same employee back in December. At that time, I chose to give him the benefit of the doubt and assumed he may simply have been having a bad day. Experiencing essentially the same type of behavior again more than six months later makes me concerned that this is not an isolated incident. Labcorp has otherwise been a place my family has trusted for years, which is why this experience stands out so much. Front-desk staff are often the first point of contact for patients, and basic courtesy, patience, and respectful communication should be a fundamental part of that role. I hope Labcorp management takes this feedback seriously and looks into the interactions and training of the front-desk staff at this location. It would be unfortunate for the behavior of one employee to undermine what has otherwise been a very good experience with this Labcorp location over many years.

I can't recommend Dr. Mielke highly enough. I've been her patient for over seven years, and…read morethroughout that time she has consistently provided exceptional care. She is incredibly knowledgeable, thoughtful, and truly takes the time to understand the whole person rather than simply treating symptoms. I have always felt heard, respected, and actively involved in every decision about my care. What truly sets Dr. Mielke apart is her dedication to staying at the forefront of medical research. She is always up to date with the latest scientific findings and evolving approaches to patient care, and she thoughtfully incorporates that knowledge into personalized treatment plans. It gives me tremendous confidence knowing that my care is both evidence-based and tailored to my individual needs. She explains complex medical topics clearly, never rushes appointments, and genuinely cares about helping her patients achieve the best possible health outcomes. The entire team at Optimal Spectrum is also professional, responsive, and welcoming, making every interaction a positive experience. After more than seven years under Dr. Mielke's care, I can confidently say she has exceeded my expectations in every way. If you're looking for a physician who is compassionate, exceptionally skilled, and committed to providing the highest standard of modern, evidence-based care, I wholeheartedly recommend Dr. Mielke.

She expertly put me on a regimen of non-toxic compounds that she adjusts every quarter based upon her indefatigable updating of the advanced science on which she relies. She is both caring and direct. I credit her with much understanding and support and, essentially, keeping me alive while I avoided toxic recommendations from my more traditional team. The complexity of Dr. Mielke's patients means that while she has a killer memory and excellent medical training plus nearly a quarter century of running her clinic, she simply cannot know everything that will ultimately be the key to a particular individual recovery.

If I could give them 5 stars and base this on the staff only, that's the way it would be. Now for the Quest part.....they need more employees there. They don't care if you have to sit for two hours after fasting in the morning, because they are too cheap to add more staff. Then, I recently noticed that they have a shrinking staff doing more work. Before they just completed forms by hand, whereas now they have to key everything into the system. This probably adds five to ten minutes per patient. Then they got rid of the receptionist they had. I overheard one of them telling another she was starving because sh had been working for seven hours and couldn't ever get just a second to eat. They didn't mean for me to hear this and felt horrible that it might sound like they were complaining. This wasn't the case at all. So ZERO stars for Quest the Company, and Five stars for the nice people that work there and work so hard with too few resources.
