Providence PatientMy experiences with Dr. Martyak have all been positive. I feel cared for and seen by the doctor. I leave her office feeling confident because she has provided thoughtful, wise and compassionate care for my condition and will continue to do so, regardless of where the diagnosis and discoveries lead.

Providence PatientDr Martyak is an excellent, sensitive, knowledgeable clinician. Her scribe takes the notes while she pays close attention to her patient. I am very pleased to be working with her. Because she has the reputation that she has, it was a little challenging to get an appointment- but it eventually worked out.
Providence PatientAll good. Just wait time for next appointments are long. She's popular!
Providence PatientMy provider is an excellent doctor. It's just difficult to get an appointment within a reasonable time.
Providence PatientI corresponded with Dr. Martyak thru the portal. I wrote I was "feeling alone" in the process of understanding my condition. The next morning I received a phone call from her office, immediately offering me an appt. Not only did Dr. Martyak "hear" me but she also had me come into the office to support me, continue to educate me about what I was going thru and she offered additional support from her PA. I could not have asked for me. I am so confident in Dr. Martyak and am grateful she's my doctor.
Providence PatientNo bad experience. Dr Martyak is just back up with appointments so one needs to book an appointment for her very far in advance.
Providence PatientDr Martyak is an excellent physician. She or some one else needs to train her staff to answer phones, schedule appointments, understand. Urgencies and be more patient focused and driven to address patient needs. Staff is the issue.

Providence PatientGOOD EXPERIENCE.
Providence PatientDr. Martyak squeezed me into her very busy schedule at the last minute. She thoroughly explained my issue & gave complete instructions for managing my condition.

Providence PatientAbsolutely no bad experiences. From front office staff to seeing Dr. Martyak they make my visit a pleasant one. Thank you to everyone.
Providence PatientDr.Martyak is an exceptional doctor. The wait for appointments is long. Providers other than the doctor attempted to answer questions on the patient portal when they clearly didn't know my medication dosages, history, or prior instructions from the doctor, and these people gave instructions that made no sense. Thankfully the doctor sent a message later with clear instructions.
Providence PatientWonderful and experienced, would return to this provider!

Providence PatientDr Martyak is terrific! Very smart, knowledgable and relateable. The only problem with seeing Dr Martak is you always wait a long time for your appointment to start. The wait is well worth it, but it has always been that way. Scheduling seems to be a persitent problem.

Providence PatientDr Martyak is one of the best and nicest doctors. Her office staff is great.
Providence PatientProfessional, respectful, and caring.
Providence PatientI was very impressed that the doctor had looked at my history before coming into the office. She was able to clearly explain the conditions that were a concern. I appreciated the fact that she had a scribe so she could address my concerns without having to also type. It was a great relief to have had a visit with a doctor who seemed to care about my Issues. (Recently, I had an unfortunate experience with a couple of doctors, other than St. John's, who stayed on the computer with their back to me during the whole visit.)
Providence PatientDr. Martyak is an excellent doctor but once I leave the office it is next to impossible to get in touch with her. If I have a question I have to use her portal which she only responds to once a week. This type of communication makes me very uneasy after having two surgeries in a year and a half.
Providence PatientDr. Martyak always comes up with new ideas of how to treat my digestive issues. She is thoughtful and inventive.
Providence PatientExtremely positive experience. The physician was knowledgeable and friendly, and a patient listener. She explained the outcome, and provided a plan for the future.
