Dr. Sisselman was very distant, abrupt and at times accusatory. As I came to Dr. Sisselman with longstanding asthma and inquired about.what appeared to be a fat deposit on my back, something I had recently noticed ... I was told "don'ttell me you've just noticed this", also when asked about the dosage of my medication, I mistakenly said 125mg instead of 100mg.... I was snapped at and informed the medication is not available in that dosage. In conclusion, I left the office without completing the visit ... however my insurance was charged the full rate. If you want to be yelled at talked down to ... schedule your appointment today.

Dr. Sisselman runs a very efficient operation with an on-time accuracy that sets it apart from other practices. He and his staff are knowledgeable, engaging, and thorough. Results of blood tests are available quickly, and you can schedule appointments and access information easily through his portal online.

I see the doctor one a year for a physical and that's pretty much it so I look for things like convenience, ease of scheduling and wait time. Dr. Sisselman and his office hit the mark on all of these. Friendly, no wait time, nice office and thorough.

As a trained DO, I expected him to do some Osteopathic Manipulation on me, but that never happened. Instead he referred me to a Physical therapist, whom I called several times, with no response and no call back.

Horrible! He doesn't listen to what a patients needs and has no clue how the pharmacy works! Can't distinguish generic and non-generic plans the price makes a big difference to what patience can afford . It's a fighting battle! When theyrefer to doctors don't have right area codes and no addresses... The nurse wraps up old gauge and not professionally done.. Nothing routine. U have to look out for yourself... Three days to wait for my meds.. Between him and the pharmacy still waiting.. Didn't fax to begin with... Nothing but aggravation since day one.. Why would u prescribe same medication when patient brings them in and shows him and still prescribes ! There is something wrong!!! never bothers to delete old medications...

I have never waited longer than 5 minutes to be called out of the waiting room. The front office staff are always polite and professional. The back clinical staff are always pleasant, helpful and efficient. I just met Dr.Sisselman for thefirst time today who had a great bedside manner and had easily caught up on my previous issues last visit. My family and I usually see Amy Roberts their physician assistant who is punctual, professional, awesome bedside manner and extremely thorough! We are very fortunate to have found Dr.Sisselmans office!

Dr. Sisselman has the best bedside manner. He listens and takes his time when you are with him. I never feel rushed or like a stranger with my own doctor. I have recommended him to several friends and family members, andthey echo my feelings. I have also been treated by Mrs. Dr. Sisselman and she is just as wonderful.

Dr. Sisselman is, hands down, the best PCP I've ever had. In addition to being very knowledgable, he has a laid back demeanor that puts you at ease while still maintaining the utmost professionalism. As a young patient, it's sometimes easierto be dishonest with doctors than deal with with the judgement and condescension that many tend to dole out after you've chosen to be upfront about your personal choices. If you can't be honest with your doctor, you have the wrong doctor. Bonus - the wait has never been more than 20 minutes. Double bonus - the front desk receptionists and medical assistants are incredibly competent AND nice (shockingly enough, this has become a rarity since mean ex-sorority girls with no direction have chosen this employment setting on the sole fact that they can "wear totally cute scrubs" on a daily basis). Dr. Sisselman and his entire office staff are highly recommended! I hope I don't move anytime soon.
