Dr Weitzen was such an amazing surgeon. He has the best bedside manner, does a great job of explaining the procedure, recovery and equipping you with all the necessary information. During my interactions with him I was always treated with kindness, compassion and respect.

I recently had the pleasure of being treated by Dr. Weitzen for a cyst removal procedure. From the moment I met him, I was impressed by his approachability and professionalism. Dr. Weitzen explained the entire process clearly and addressed all my concerns with patience and understanding. The procedure itself was handled with exceptional care and precision, resulting in a swift and successful removal. His friendly demeanor made the entire experience much more comfortable than I anticipated. I highly recommend Dr. Weitzen to anyone seeking a skilled and compassionate surgeon.

Dr. Marks was friendly, professional, and courteous throughout my hernia evaluation. She had an excellent bedside manner, answered all of my (many!) questions, and clearly explained the next steps. I would highly recommend her.

April 7, 2025Richard D.Verified patient

Dr. Yael Marks exemplifies exceptional care and empathy as a General Surgery Specialist. During my appointment, she provided thorough explanations and presented treatment options, showcasing genuine concern for my well-being. The efficiency of having both procedures on the same day was remarkable, made even more seamless by Dr. Marks' attention to ensuring minimal discomfort. I highly recommend Dr. Marks to anyone in need of general surgery; her dedication and compassionate approach truly stand out.

Professional and extremely patient and understanding.

May 29, 2024Mimi B.Verified patient

Absolutely wonderful doctor and very knowledgeable. So happy I found her and highly recommend! Even if you live far she is beyond worth the drive. Smoothest experience I’ve ever had in a doctors office and I came in with a very vulnerable and painful issue.

June 22, 2026Cali R.Verified patient

I was very fortunate to be seen by Dr. Aronova and to be squeezed in that same week for surgery. She was my second opinion, and after sitting down and listening to her, I felt very comfortable with having surgery. I went in for a cholecystectomy and appendectomy and was worried about my scars. She assured me that she would do her best to hide the incisions and she was right. I have no regrets. She worked magic, and pain was minimal. I would highly recommend her.

May 17, 2026Angela L.Verified patient

She is great! She was on time, took the time to explain everything and answer all my questions. Super informative and patient. Would highly recommend and her office was great and ran on time

January 28, 2026Allison T.Verified patient

Listened well, calmed my panic about the issue at hand and set an appt for next steps immediately on her calendar while in the exam room still.

November 27, 2024Initials hidden

Dr Aronova spent quite a bit of time with me. More time than any doctor has spent with me in years. She explained the tests that she was ordering and how she would do the surgery once the information came back to her. She had a great bedside manner and seemed more than competent in her field. No one looks forward to surgery, but she made me feel like I was in good hands.

January 25, 2024Karina H.Verified patient

Staff are super friendly and made my visit as easy as possible

April 5, 2023Ariel M.Verified patient

The doctor was just not as engaging. There would be moments of silence inbetween questions. Didn’t make me feel reassured at all. Seemed to have no interpersonal skills. Very disappointing.
