Serious Concern Regarding Unprofessional, Unsafe Blood Draw, poor technique and poor hygiene on…read more8/20/2026 by Kalinda Smith MA On Thursday, August 20, I visited Dr. Thomas Avella with my son for our annual physicals. My initial encounter with Medical Assistant Bryan was excellent -- he was friendly, professional, and thorough while obtaining our vitals and medical history. However, the blood draw performed afterward by Kalinda Smith, MA, was deeply concerning and did not meet basic standards of hygiene, professionalism, or safe phlebotomy technique. Smith entered the room without introducing herself. When I asked whether she was a nurse or phlebotomist, she stated she was a medical assistant. Immediately afterward, she stepped into the cabinet area and tied her shoelaces. She did not wash her hands before preparing the blood draw equipment and after she tied her shoelaces. As a medical professional myself, I found this extremely unhygienic and unacceptable. During the blood draw, she inserted the needle into my left arm but did not obtain blood. She repeatedly moved and manipulated the needle inside my vein, causing significant pain. When I told her she was hurting me, she argued and insisted I "did not drink enough water," despite the fact that I told her I did. Eventually the blood began flowing normally. Additionally, she left the tourniquet on for the entire duration of the blood draw, which increases the risk of hemolysis and is not appropriate technique. Her communication throughout the encounter was dismissive and unprofessional. When I asked her to confirm whether Dr. Avella had sent my prescription, she responded in an annoyed tone and rushed me to provide a urine sample. I only learned her name from the printed visit summary. After leaving the practice, my arm became swollen, painful, and later developed bruising, which I have documented in photos. In my entire life, I have never experienced swelling or bruising after a blood draw in any hospital or clinic. This was the worst blood‑draw experience I have ever had, caused by Kalinda Smith's poor technique and poor hygiene. She didn't even deserve one star for her unprofessional behavior. Crystal Run has always maintained high standards, which is why this experience was so disappointing. If Smith is not yet proficient in blood draws, patients should not be used as test subjects. She requires additional training in phlebotomy technique, hygiene, and patient communication to ensure safety and maintain the quality of care your practice is known for. For other patients: if you encounter Kalinda Smith, please be careful. Based on my experience, I strongly recommend not letting her draw your blood. I trust Crystal Run will take this matter seriously and address it promptly.

Now I see his daughter Dr Heidi who does more fun stuff like botox for me and now checks my skin (and found a melanoma on me!) I also like that their nurses remember the patients and make you feel comfortable. It is worth paying off my insurance to go to this office!

Even before looking at the affected area, he wanted to do a whole body check - to be thorough. He had a hunch of what the issue was, took a swab and came back 15 minutes later. I was a bit shocked and impressed when he said he looked at the sample under the microscope and had diagnosed me and was able to point to the evidence all while I waited! It turns out I have psoriasis and have had it for over 10 years. Previous doctors completely missed this and some even misdiagnosed me. I was delighted when he gave me information to read, sample medication and helpful tips on how to cope with the symptoms. I would highly recommend Dr. Rosen - he is everything you want in a Dr. and more!

You can't put a price on your medical care. Being able to find a doctor that I trusted and felt safe with has given me immeasurable peace of mind. I love Dr. Heidi Waldorf because she's truly brilliant and always interested in my total well being. Dr. Waldorf has been my dermatologist for over 5 years. She's knowledgeable and discusses and explains everything openly and honestly--I always have options. I'm not just in "good" hands. I'm in her skilled and magical hands that work wonders. I was so relieved that I could do fillers and avoid surgery to achieve the look that I wanted. With a combination of injectable filers (radiesse, belotero, restylane ) -and trusting in Dr. Waldorf to know exactly where to place the fillers, I was able to sculpt and lift. I looked just like me only younger and better. The best part is that I receive wonderful compliments. Everyone thinks I look terrific. They assume I had a nice long vacation- can't beat that!

I went to this spa for a medical issue requiring Botox. When I called in the receptionist…read moreexplained the doctor was not accepting new patients but that I could make an appointment with their nurse. I was hesitant, so she explained that she's been doing this for 17 years implying she really can do whatever a doctor can. To make a long story short... when I went in the nurse explained that any Botox around the eye causes drooping. I told her I didn't want it 'around' the eye, just near the eyebrows to deal with involuntary eyebrow movement and that I would defer to her where to put the Botox, as long as I get the results. Well, she put only a tiny amount near the 11 lines, which had absolutely no effect on the brows.... So I decided to check out some videos to see where the injections are normally placed. I went back a second time and told the nurse where I saw the injections need to be placed and she told me, that she could only place it higher up... after several questions and some confusion, she finally admitted that the procedure I needed (close to the eyebrow) can only be done by a doctor and that she was not qualified!! Why did she not tell me this in the first place? We had discussed some upper lip lines as well and the second time there she told me she could do those.... same story... she place the injections on the lip line proper... with no effect other than to turn my lip purple.... when I looked online to see videos the injections are normally placed much higher up on the lip. What is up with this place???? Extreme underhanded.

Only con was I was informed the service would cost me $50. When going up to the desk to pay I was charged $65. Not sure why it went up $15 dollars. Looks like next time I'll have to triple ask before getting into the room for a service.
