I have some difficult health issues that she took seriously and dealt with effectively. She strikes me as a shy person, which may come across to some people as coldness.

Now I mostly telemed with her, but I go in once a year to see her in person. She always listens to you with an open mind. She spends as much time with you as you need. She never rushes you. If you need to talk to her, just make a telemed visit. It's the fastest way to talk with her. I value everything she tell me. Really excellent Dr!

I tried this practice twice, and it was incredibly disappointing. I set the appointment up through…read moreZocDoc, when I called to confirm they left me on hold for 30 mins and then acted like I was wasting their time. Later, they had miss written a doctors note for me, and when I called back to correct it, they never returned my call, and established care elsewhere instead. Then they sent me a bill 3 months later, and when I called to pay it they left me on hold for 10 mins, then hung up on me. When they finally did answer the next time, the receptionist gave me a whole riggamaroll about how that isn't her job. I have no idea what your division of labor is, and I don't care. Then when I asked if she could confirm the balance, she kept talking over me and telling me I was yelling. At that point, I just hung up and figured out how to navigate their archaic website. The doctors might be fine, I could barely tell because I only got 45 mins of actual visit out of this whole fiasco. But I would absolutely not waste your time here.

This review is purely based on me making a new patient appointment today to see Dr. Tiffini Lucas…read more I spoke with Betty, the receptionist and let me tell you just how RUDE she was in taking my information. She was very short with me, no please or thank-you and with much attitude. When I asked if she wanted my insurance info just to make sure this practice accepts it she responded with "Well, do you wanna give it to me? How will I know if you don't give it to me?" Seriously??? The ONLY reason why I went ahead and scheduled the appointment is because Dr. Lucas had great reviews both on Yelp and on the practices' professional website. But this Betty character should definitely be re-evaluated as being the spokesperson for the business. Just not a good look. If all goes well, I will make sure to amend my review here on Yelp...

They booked my elderly mother for an appointment tomorrow and called me after 4pm today to cancel it. The reason? You can't have two appointments in the same week! This was for a nerve conduction test she was told she had to have. Patients and their caregivers deserve to be treated better. Shame on you Monica. I can't tell you anything about Dr. Nikhar. I called and spoke with Monica months ago to schedule an appointment with Dr. Nikhar. Guess what? When we arrived for our appointment with Dr. Nikhar we had an appointment with an NP who was very good. She told us we NEVER had an appointment with him, we had an appointment with her. Watch out Maryland stay far away from this practice!!!!

I wouldn't recommend this doctor's office. The front desk staff aren't customer service oriented…read moreand I had a really bad experience with them. I gave them my new insurance card that has the same member ID as the old one but a different group number than my old card. After my appointment, I noticed that my bill was pretty high and saw I was charged $176 without my consent. This seemed really odd and I called my insurance. I found out they used my old insurance information from my older plan that is no longer active. That's why I owed the full amount. I called their billing department and gave them my new insurance information so they could resubmit with my new insurance information. They said this could take a month or two to process. We're getting close to two months and I have yet to get reimbursed the $176. I was recently told by one of the billing people that one of my claims is in appeal and may not get approved which means I may have to pay the full amount. I told them this was unacceptable given this wasn't my mistake but theirs. This whole thing is stressful and should have never happened. The front desk people need better training because this was a super careless mistake. I'm dealing with so many health issues I really don't need to worry about something else. I get the sense they're short staffed and need to hire more people. I switched to Capital Neurology and Sleep Medicine. My experience here has been a lot better. The front desk people have done ok and my new doctor explains things in detail, is kind and friendly.

But she was the most amazing doctor for my dad. She really stayed on top of what was going on and would answer texts and phone calls at all hours. She looked over his medication bottles every time to be sure he was taking the correct medications and doses. Having an echo machine in the office was fantastic to keep track of his heart. When he needed oxygen at home, she made it happen that same day. I don't think any other doctor could have done that! She really went above and beyond to take my father's wishes into account. My father died at home at 95 and I believe those last few years were due to Dr. Barold. If I lived in the area I would definitely want her as my own doctor.

I thought I had a Upper Resp Infection, but she said it sounded more like bronchitis! And boy, was she right because the meds she prescribed had those symptoms under control within two days! Other places I've gone to have missed the mark every time...they usually misdiagnose me and give me the wrong Rx!

I've never had to wait more than 5 minutes in the waiting room before being called back & she's very thorough in her exam (she doesn't try to rush you in & out like some medical cattle call). I was so pleasantly surprised by the fact that SHE actually returned my phone call, not a nurse or assistant - Dr. DiFresco herself (and she got back to me in 10 minutes!). No other physician has ever called me back themselves, let alone within minutes of calling. She's originally from the same neighborhood in Brooklyn that I'm from, so between her sweet, calming nature & her Brooklyn accent, I felt like I was right back home with my mom taking care of me again. I can't say enough positive things about Dr. DiFresco & I'm so grateful that I found her (for those interested, this is an all female practice).
