Delay in meeting with Dr Krishnasamy. He was courteous and explained the reason being extended times with previous patients

Dr was more attentive and open in his examine room demeanor than in prior meetings. However, I kept feeling that they were not really listening to my personal observations of my current health, while they were processing my historical data.

I have a repetitive 28 day cadence prescription for 5 mg oxycodone. My pharmacy constantly tells me they have staffing issues. Having scripts loaded into pharmacy for 3 months at a time has eliminated my pharmacy's excuse for poor staffing. This medication has tremendous impact on my quality of life due to a lumbar compression fracture and associated pain.

Dr Krishnasamy is an excellent clinician-very knowledgeable about best practices and about my particular health issues. He is warm and compassionate, yet professional and efficient in his interactions.

Dr.K is amazing! He is data driven, and takes copious notes for me to review in MyHealth. He motivates me to make change, and keep data pertaining to my health.

Physician is more interested in prescribing pharmaceuticals based on a single number in my lipids test, rather than discussing the complex results of the panel in detail to determine proper course of treatment, if any. The only thing that matters Is a statistical calculation of risk based on age and one number in the results. Not the interaction between the panel tests. Not nutrition. Not health history. Not the fact that my lipid results clearly show no need for statins. Also, we are always hurried in our appointments. For this annual physical, I had no more than 15 minutes with the physician. I intend to leave this practice.

Dr K is a thoughtful, personable, excellent physician, I feel lucky to have him as my PCP.

As always Dr Krishnasamy shows interest in my Health/Wellbeing.

Great Doc but appointment length is too short. And booked too far out.

  Jul 21, 2023
Everything was great. Dr. Krishnasamy is very easy to discuss things with, and thoroughly answered all my questions. I just started seeing him earlier this year and I am very happy with my decision to come here.

Makes my health goals easy to understand.

Clinic is located in a somewhat unsafe neighborhood.

  Jun 16, 2023
Dr. K seems like an outstanding primary care physician and Internist. He reviewed and understood my entire medical history and listened to all of my concerns. I feel lucky to have him as a PCP!

I am not convinced my response will remain confidential. Any electronic communication can be breached. I absolutely have some concerns with provider, but this concern is not related to his professionalism or expertise.

Less than 15 minutes for an annual physical seemed very rushed.
