Middle Aged Healthcare Consumer – Sep 17, 2021
I absolutely would recommend anyone and everyone to Dr. Parker and his Team. Dr.Parker is my mom’s G.I. Doc and as a result of the phenomenal care she received when I was given the directive to get a colonoscopy from my PCP, Dr. Parker & Team was my first choice. Received a new patient package with information 2 weeks before my appointment. Ladies at the front desk were exceptionally welcoming. My nurses pre & post were super warm. The nurses ensured I was comfortable, kept me updated, and spoke to me about the process from beginning to end. Tonya Sloan (Anesthesia) PHENOMENAL! I was OUT and UP again. Dr. Parker SUPER nice…awesome bedside manners, had an info session before I was down for the count and saw him again to go over the procedure before I was discharged. Next day…his nurse called to check on me. Yes…Five Stars for Dr. Parker, Tonya Sloan, & Team!

Dr. Parker and his medical staff are wonderful! Dr. Parker takes the time to explain everything you need to know and answers any questions or concerns you have. For the first time I can honestly say that this whole office operates as a TEAM and does not a Clique environment! You’re greeted and treated with respect, not as a number in rotation. I have full confidence in my choice of care with Dr. Parker and the medical staff. I have recommended family, friends, even strangers to Dr. Parker for Gastrointestinal concerns and exams! You’ll be good hands!!

Man, this doctor is amazing. Dr. Parker really cares about his patients. But, he also doesn’t play any games or sugar coat anything either. He ordered a battery of tests for me but also game me instructions on how to help myself, and explained that he can only help me if I’m willing to take his advice and follow the rules provided. I really feel like this doctor cares about his job and his patients.

I'm a new patient of Dr Calvin Parker III. I needed to have a Colonoscopy soon, and Dr Parker had great ratings, so I chose him. Dr Parker and his staff lived up to those high ratings. He was calming and pleasant. and his staff was very nice and helpful . I was very anxious or you could say ( petrified) about the whole procedure. But I followed his advice on following all the instructions for prep so they could get a clear view of the colon to see if there were any problems. The day of the Colonoscopy I was shaking inside . I went to the EndocentreofBaltimore . 1838 Greene Tree Rd Ste 180. the nurse that called me back prepped me while calming me down some and then the Anesthesiologists smile calmed me down more as he wheeled me away , then I got a nice calming smile from Dr parker on our way to the room for the procedure. Then after I woke up Dr Parker said everything went well . I was so happy and relieved. Thankyou so much! Dr Parker . And everyone else that helped me.

Dr. Parker is the most caring medical doctor I have ever met. He takes the time to listen and address my medical needs. After having lab work, he followed up and called to give the results. I had previously seen a doctor at Johns Hopkins and was not happy with his lack of compassion and empathy for me. Hands down this is the best doctor and I recommend Dr. Parker to everyone who needs a GI specialist.
